T-S 12.392 recto and verso
At the end of 1103, a Jewish trader from North Africa wrote a letter as he waited to embark on a voyage to the western coast of India. He filled his letter with literary flourishes and detailed complaints about his travels before sending it to his relative back home in Tripoli, present-day Libya. It is unclear whether the letter ever reached its destination; we do know that it eventually arrived in Fusṭāṭ, entered a Geniza, and is today in the Taylor-Schechter Collection of the Cambridge University Library. While the merchant’s name and fate are unknown to us, his letter provides us with exceptional detail about the mercantile networks that linked Egypt to India in the early twelfth century.
Of the more than seven hundred documents from the Geniza attesting to the role Jewish merchants played in the medieval Indian Ocean trade, this document represents a rare instance in which a merchant provided dates for different legs of his journey to India.2 It is therefore of critical value to our understanding of Indian Ocean travel logistics and the personal considerations that shaped merchants’ travel decisions. The letter is on a sheet of paper measuring 9.00 × 18.00 cm, with twenty-four lines on the recto and seventeen on the verso, plus the angled writing in the right-hand margin that is typical of Geniza letters. Most of the writing is clear, except for a tear in the upper right-hand corner and a few places where the ink has faded. It is in Judeo-Arabic with some biblical references in Hebrew. Alan Elbaum and Marina Rustow edited and translated it on the Princeton Geniza Project site, and we thank the India Book project team for giving us their permission to use their draft commentary for this project.3
Our interest in this letter grew out of our participation in a graduate seminar taught by Elizabeth Lambourn and Marina Rustow at Princeton University in the Fall of 2025 on the material culture of the medieval Indian Ocean world. The precise dating of this letter and the pathos of its author each caught our attention for different reasons. This was the expression of a man eager to succeed in the India trade while remaining committed to the obligations of Jewish ritual life. He expressed the despair he felt at the difficulty of his voyage through both humorous allusions to the Hebrew Bible and Arabic toponymic puns, a testament to his position in the overlapping mercantile and religious networks of the medieval Middle East.
Reflective of our different research interests, our discussion here focuses on three elements of the letter: seasonality and travel logistics, the constraints of religious obligation during travel, and the writer’s rhetoric. We open with a discussion of the logistical considerations that informed our merchant’s journey, including his awareness of seasonal variables such as the Nile flood and the Indian Ocean’s monsoon patterns. This leads us to discuss the coincidence of his travel with Rosh Hashanah and other important Jewish dates, wherein we suggest that he may have preferred to observe these holidays on land before embarking to India. We conclude our discussion with a close reading of his aforementioned wordplay, considering it as evidence of his immersion in both Arabic and Hebrew literary traditions.
This discussion is grounded in our reconstruction of this trader’s itinerary, which we developed by corroborating the letter’s internal chronology with evidence from contemporary travel accounts (Table 1) and considering the Jewish and Muslim holidays that marked his travel (Table 2). This multifaceted approach convinced us of the importance of this letter, among other Geniza documents, in illuminating the pragmatic, religious, and literary fabric of medieval lives.
Navigating the Nile
Our writer’s journey took him across several waterways — the Mediterranean, the Nile, and the Red Sea — before he reached the shores of the western Indian Ocean. At the moment when he penned this letter, he was anxiously awaiting his journey across the Indian Ocean, writing to his relative: “I’m about to cross the great Sea—no mere sea of Tripoli, this!”4 He would, he writes, much prefer to wait until “the seas even out,” but he appeared to have no choice in the matter.5
The Nile, Red Sea, and Indian Ocean are all highly seasonal waterways, and that seasonality affected this trader’s itinerary and experience. To appreciate these seasonal travel patterns, we have reconstructed the chronology between each of his stops along the Nile and Red Sea using the explicit dates he mentions in tandem with other travelers’ accounts (Table 1). After bringing together these types of evidence to understand how traders navigated seasonal waterways, we explored the coincidence of his travels with Jewish and Muslim holidays (Table 2).
Table 1 (Timeline)
This table shows the main stops in our writer’s itinerary (column 1). He provides dates according to the anno mundi calendar (column 2). We have converted these dates into the Julian calendar (column 3) and indicated our source for these dates (column 4). Dates in italics are based on contextual analysis, dates in roman rely on an approximate time supplied by the letter-writer, and dates in bold are explicitly mentioned by the author.

Table 2 (Jewish and Muslim holidays)
The festival calendar was a critical force in shaping everyday lives in the medieval Middle East. This force was particularly felt by our writer, whose journey coincided with many important holidays on the Jewish and Islamic calendars. This table shows the writer’s location relative to the dates of these holidays.

Our merchant’s journey began in the Mediterranean as he sailed from his home in present-day Libya to Alexandria. He writes nothing about his journey from Tripoli to Egypt; based on other Geniza letters, we can infer that he might have arrived in Alexandria in late August, since we know from contemporary Geniza letters that a Maghribī merchant might spend the winter at home in the Maghrib before sailing eastward, and that ships heading east often arrived in Alexandria in late August.6 This would have positioned our merchant to travel up the Nile to Fusṭāṭ when the Nile was high, since the inundation happened in August and September. A canal linking Alexandria to the Nile likewise depended on high water levels, often opening in September and remaining navigable for a few months.7 The ideal timings for travel from the Maghrib to Alexandria and from there to Fusṭāṭ were thus well-aligned, suggesting that this leg of his trip would have been relatively straightforward. Given our writer’s tendency to wax verbose about the ordeals he faced and the novelties he encountered on his journey, his silence on this initial trip bears out our assumption that it was smooth and familiar.
Our writer does not mention when he arrived in Fusṭāṭ. We can infer from Geniza evidence and environmental constraints that he could have arrived as early as September 1102. The next point of temporal orientation he provides is the end of Iyyar 4863 AM, equivalent to early May 1103, when he set out from Fusṭāṭ.8 If he had arrived in the Fall, this means he would have stayed in Fusṭāṭ for approximately nine months, likely socializing with the city’s many Jewish merchants. It was there that he met Makhlūf b. Moshe, a prolific Indian Ocean trader known as “Happy Eyes,” who enticed him with talk of a far-off land, India, and its countryside settlements (rustāq).9 To reach it, our aspiring trader would have needed to travel upstream on the Nile, head down the Red Sea, and then sail with the southwest monsoon winds to India.
The Nile flooded annually. Near Aswan, the inundation began in July and peaked in mid-September. The water levels began to fall by October and by the winter, the Nile was shallow and would remain so until the next inundation.10 A shallow Nile made travel much more difficult. Nile navigators relied on the wind to go upstream and used the current to go downstream toward the Mediterranean. Heading upstream to Qūṣ, a hub for medieval trade, our merchant would have desired strong northerly winds at his back and a deep Nile to carry the boat. The optimal time for him to set out, according to John P. Cooper, would have been between August and October.11 Our writer chose to set out in May.
A May departure from Fusṭāṭ would have made his journey upstream significantly longer and more arduous. The river would have been shallow and narrow, making it difficult to navigate. What made it feasible, albeit difficult, for travelers to sail upstream on a shallow Nile? They would have needed a smaller boat, with a shallow hull and minimal onboard weight, to ensure a low draft so that the boat would not become grounded in low waters. Cooper shows that in Upper Egypt, a vessel with less than a one-meter draft could sail the whole year, while a vessel with a 1.5-meter draft could navigate only between mid-June and mid-March.12 Yet even with a smaller boat, the journey could be troublesome.13 When the Nile was low, a boat risked grounding itself in the sand banks which dotted the river’s course.14 Sailing upstream from Fusṭāṭ to Qūṣ, our writer relied on northerly winds. These northerly winds were year-round in Upper Egypt though they increased in frequency and force with the Nile’s yearly inundation. As the waters rose, the winds grew stronger. This meant that in May, the traveler’s boat faced twin challenges: increased risk of grounding and decreased velocity.15 Often, boats traveling during the low Nile season required laborious towing to advance upstream due to weak winds.16 Not to mention, carrying cargo would require higher water levels to accommodate the increase in draft. If our traveler sailed up the Nile in May, he would have had to forgo cargo and sail in a shallow-depth passenger craft, but the journey would still be difficult.17 In spite of the low winds and water, he left Fusṭāṭ in early May and traveled upstream.
During the high Nile season, Cooper estimates that traveling from Cairo to Qūṣ would have required between fourteen and twenty-two days.18 That wasn’t the case when the Nile was low. Our writer reports that “we reached Qūṣ in two months.”19 In May, sailing conditions were difficult since the Nile waters were still extremely low, so his travel took two months instead of two weeks. If he had waited a few more months, his Nile journey would have been much easier. Why did he set out when the waters were low?
Part of the answer is that it was impossible for travelers to align the seasonalities of these three waterways. If our writer had waited until the Nile was high, he would have missed the Indian Ocean sailing season. At best, he could try to align two of them by sailing during the low Nile, and then benefitting from the outbound Red Sea season, which coincided with the summer and the end of the southwest monsoon in the Indian Ocean.
This traveler was a novice at the Indian Ocean trade, so we can’t take his decisions as representative of all travelers. But he was not the only one to leave Fusṭāṭ for Qūṣ in May. A more famous traveler, Nāṣir-i Khusraw, the eleventh-century author of a Persian travelogue, also left Fusṭāṭ for Qūṣ in early May.20 Geniza documents confirm that others traveled between Fusṭāṭ and Qūṣ when the Nile was low. One thirteenth-century writer explains that it had taken a letter fifty days to reach Qūṣ from Fusṭāṭ.21 Another mentions that a group had taken forty-five days to travel on the Nile from Fusṭāṭ to Qūṣ.22 While our writer’s two-month journey was longer than the ideal of two weeks, clearly not all travelers set off during the ideal season.
Sailing on a low Nile was difficult, but it might have seemed a more attractive option than a challenging Red Sea season. The Red Sea is split into two wind regimes. Northerly winds dominate year-round in the northern half of the Red Sea, an aspect of the same climate pattern in the Nile Valley that slowly propelled our writer’s boat upstream from Fusṭāṭ. Starting just south of ʿAydhāb and Jidda, the wind regime is related to seasonal monsoons. In the southern half of the Red Sea the winds blow towards the south during the summer monsoon, while during the winter monsoon they blow north. Between June and September, a traveler heading outbound from ʿAydhāb would enjoy northerly winds at his back during the entire journey. By October, navigating the southern Red Sea would be more complex.23 Thus our writer needed to set sail during the summer monsoon—the same monsoon which could greatly accelerate his journey across the Indian Ocean.
The best times for travel on the Mediterranean, Nile, Red Sea, and Indian Ocean and the time required for each leg of the journey did not, then, perfectly align. Travelers were forced to travel in less than ideal conditions on at least one of these major waterways. An early May departure meant a low Nile, but this was the latest departure which would allow travel south on the Red Sea and eastward to India during the ideal seasons for those legs of the journey. While our merchant was new to the India trade, his decision to depart from Fusṭāṭ during a low Nile was not a mark of his inexperience.
The challenging trip on the low Nile paid off: he reached the Red Sea in time to catch the best sailing season. After disembarking the Nile at Qūṣ, he traveled across the Eastern Desert to ʿAydhāb, a Red Sea port. He does not specify how long it took him to cross the desert, but based on contemporary accounts we estimate that it took around three weeks.24 He thus set out from Fusṭāṭ on the Nile in early May, disembarked, and arrived in Qūṣ in early July. He then traveled overland, reaching ʿAydhāb later that month.
Reaching the Red Sea port of ʿAydhāb in late July was ideal: he could catch the northerly winds that run down the Red Sea in the summer.25 By arriving in late July, he had more than enough time to reach an Indian Ocean port before the end of the sailing season in late September.26 We can trace his journey southward on the Red Sea, since after ʿAydhāb he stopped (and punned) at three more ports on the western coast of the Red Sea: Sawākin, Bāḍiʿ, and Dahlak.
We do not know how long it took our writer to travel from ʿAydhāb to Dahlak, and then to the Indian Ocean port where he penned this letter. In the Roman period, a similar journey would have taken about 30 days.27 Our writer’s choice to navigate the Nile during the low season positioned him for the optimal Red Sea and Indian Ocean sailing seasons. By September, he could have reached an Indian Ocean port. But once autumn arrived, there was another season our merchant needed to contend with — that of the Jewish High Holidays.
Ritual Obligation at Sea
Drawing on the chronology established in the previous section, the present discussion suggests that the timing of the Jewish month of Tishri (roughly equivalent to September), with its concentration of holidays, may have compelled our merchant to stop and observe the High Holidays on land before embarking to India. To understand the influence of religious obligation, this section will explain the halakhic issues involved in Jewish observance at sea and their relevance to our letter.
Although our traveler does not discuss the Jewish holidays, his repeated citation of biblical passages suggests that he was a religiously observant individual bound to the rhythms of the Jewish calendar and other aspects of ritual life. Alongside the many physical challenges he faced, then, maritime life raised religious questions as well. How could a Jew maintain Shabbat observance aboard a ship? How could he properly celebrate the High Holidays far from any synagogue? What provisions did he need to maintain kashrut at sea?
These questions have led some scholars, S. D. Goitein among them, to assume that increasing religious stringency discouraged Jews from owning merchant ships between the eleventh and thirteenth centuries.28 Conversely, Sarah Arenson remarks that “on board a ship, a Jew could observe the Sabbath and holidays and prepare Kosher provisions for the whole trip in advance.”29 Striking a balance between these two positions, the letter betrays a critical distinction between daily or weekly observances like Shabbat and kashrut, which could be integrated seamlessly into sea travel, and holidays, which required planning and strategic scheduling.
Medieval maritime trade could easily accommodate several aspects of Jewish religious life. Maimonides and other authorities of the period affirm that Jews could travel on ships during Shabbat, provided that the river or sea was deep enough not to run aground and they were not personally operating the vessel.30 Other documents suggest that sea travel on Shabbat was commonplace: the trader Peraḥya ben Yosef (nephew of the well-known trader Avraham ibn Yijū) describes boarding a boat on Friday evening and later commissioning a separate vessel to avoid disembarking on Shabbat, suggesting that it was preferable to observe Shabbat at sea than in an unfamiliar port city.31 Our merchant likewise makes no mention of stopping to disembark for Shabbat during his journey. As for dietary law, it was perhaps even easier to observe at sea than during land-based travel. Merchants packed kosher provisions before departure, and they could be replenished at port stops.32 Fish, provided it was a kosher species, made for an ideal maritime protein source given its lack of associated ritual slaughter regulations.33
The observance of festivals required more involved planning. A reconstruction of our merchant’s itinerary implies that the author may have arranged to observe the High Holidays on land, thus benefitting from a quorum of coreligionists and other conveniences on shore (see Table 2). We estimate that he arrived in ʿAydhāb in mid-Av 4863 (late July 1103; see Table 1). Put in terms of the Julian calendar, arriving in ʿAydhāb in late July provided our merchant with more than a month to ensure that he would arrive at a port before Rosh Hashanah on September 5. He then spent the entire High Holiday season either in Dahlak or an Indian Ocean port city, likely Aden, where he celebrated Rosh Hashanah, Yom Kippur, and Sukkot. Only in October, after fulfilling his festival obligations in ports with established (if itinerant) Jewish communities, did he then prepare to cross “the great Sea” toward India—his situation when he composed the letter on October 28, over a month after Sukkot.
T-S 12.392 thus provides evidence for how Jewish participation in Indian Ocean trade was shaped by religious life. Although Shabbat and kashrut could be accommodated at sea with relative ease, the festival cycle of Tishri required merchants to integrate the demands of the Jewish calendar into their commercial schedules. Yet the seasonality of the Indian Ocean was at odds with the seasons of Jewish ritual life. Heading to India in September was ideal: the end of the summer monsoon accelerated the journey, and the upcoming winter monsoon was favorable for their return. But if these Jewish merchants preferred to celebrate the High Holidays on land they would not embark until October, when the transition between the two monsoons would have made for a more arduous journey to India.
Our merchant chose to celebrate these holidays on land even though it made an already difficult journey all the more complex. As he closes the letter he alludes to his anxiety about the journey ahead: “Man! If I could pay two hundred dinars to stop the ship until the sea evens out, I would!”34 This remark is only the last in a series of complaints; earlier in the letter our merchant draws on Arabic and Hebrew literary traditions to describe the misery of the Red Sea port towns through a series of derisive puns. In closing, we reflect on the rhetoric of these complaints in finer detail.
Punning through Port Cities
We have argued that this writer’s travel logistics reflect broader patterns of travel in medieval Egypt, and that the timeline of his journey suggests he observed Jewish ritual obligations during his travels. We see both these vectors at play in his rhetoric. The trader’s literary style is characteristic of both medieval Arabic literary works and biblical and rabbinic compositions, demonstrating how the two traditions could connect under the reed pen of an Arabic-speaking Jewish trader anxiously anticipating his journey across the Indian Ocean.
While wordplay is a common literary device, it appears to particular effect in Arabic literature, rabbinic texts, and the Hebrew Bible.35 Wordplay allowed a writer to flaunt his command of the Arabic language through puns that relied on polysemic words and celebrated their obscurity. Our writer frequently employs what medieval rhetoricians term jinās nāqiṣ, a form of wordplay in which words resemble one another in some letters or sounds while diverging in meaning.36 He also rhymes the final syllable of the names of many places with his (often disparaging) descriptions of them.37 This novice trader might not have been an Arabic belle-lettrist, but his rhetoric shows that he was familiar with literature, or even aspired to write it.38 Through his rhyme and puns, he demonstrates that he is at home in a literary Arabic milieu.
The puns he chooses attest to more than an individual literary flourish: other medieval Arabic works use similar place-name puns. Upon reaching ʿAydhāb, the first of these Red Sea towns, he remarks that it is a town of ʿadhāb (tribulation). The writer omits the letter yāʾ, calling attention to the phonetic similarity of the town’s name and the Arabic word for pain or torment. This ʿAydhāb/ʿadhāb pun is found in other contemporary Arabic sources, suggesting a trope shared among travelers and literati alike.39 The Geniza letters of two prominent traders spell the town’s name according to the same pun: ʿAdhāb.40 Likewise, the twelfth-century Maghribī belle-lettrist al-Wahrānī refers to the tribulations (ʿadhāb) of ʿAydhāb.41 This pun shows our trader was familiar with an Arabic pun about ʿAydhāb which was current in mercantile networks.
Our trader’s next stop was the port of Sawākin, down the eastern coast of the Red Sea. He reports that Sawākin is “akhaṣṣ mawākin,” a description that requires some interpretation in order to translate it owing to the ambiguities of both Judeo-Arabic and Arabic. Since some characters in Judeo-Arabic represent two Arabic characters, there are a few possible interpretations of אכץ depending on whether one reads the final tsade as a ḍāḍ or a ṣād. Friedman read it as a ṣād, thus akhaṣṣ and translates akhaṣṣ mawākin as the “most exceptional (metsuyenet) of residences.”42 Yet the rest of his puns are complaints. Should we understand his description of Sawākin as exceptional (akhaṣṣ) as ironic? Alternatively, Roxani Margariti read אכץ as akhaḍḍ, the elative of khaḍīḍ, formed from the root kh-ḍ-ḍ, meaning to be agitated, shaken (often of a liquid), or frightful; the ultimate meaning of the pun remains ambiguous, but Ashur, Elbaum, Gopalakrishnan, and Rustow translate it as “the most frightful of places.”43 Compounding the ambiguity, the writer bends the rules for the standard plural form of makān (place, plural amākin) to rhyme with the town’s name, Sawākin, both in the middle and final syllables, hence mawākin, not amākin. There is another ambiguity suggested by the India Book project team: mawākin is also the plural of mawkin, a highly obscure word for nest.44 This playful rhetoric continues with the next port towns, which he rhymes with their derisive descriptions. Our trader’s next stop, Baḍiʿ, “is just as the name says, the most bitter, akhaṣṣ/akhaḍḍ (exceptional or frightful) and miserable of mawāḍiʿ (places).” The following, Dahlak, is a balad muhlik — “a ruinous land.”45 These toponymic rhymes show our writer’s familiarity with an Arabic literary milieu which valorized end rhyme.
Our writer is well-versed in both the Hebrew Bible and Arabic literature and employs biblical citations with the trademark cleverness of a belle-lettrist. When describing Bāḍiʿ, the writer switches to Hebrew for a few words — ki ki-shemah ken hi — “it is just as its name says.” Why switch languages? As Goitein and Friedman pointed out, the allusion is to the story of David, Abigail, and Nabal recorded in 1 Samuel.46 Annoyed by Nabal’s response to his servants, David orders his men to gird their swords and take revenge on Nabal. Nabal’s wife, Abigail, catches wind of the plot and attempts to assuage David by explaining that her husband is just as his name says (ki ki-shemo ken hu): a fool.47 It is an incisive turn of phrase for this weary traveler: the town’s name, Bāḍi, is formed from the root ‘to cut.’ This biblical citation demonstrates our trader’s ability to rhetorically wield his Jewish education for comedic effect. In the same vein, he uses another biblical citation to describe the occasion when in Fusṭāṭ he heard the trader “Happy Eyes” talk about India. He jokes that he had not yet heard Proverbs 17:24: “The eyes of a fool are on the ends of the earth.”48 Looking back on the increasing difficulty of his journey and conscious of the perils still to come, our merchant cannot help but wonder about the foolishness of one whose eyes look to distant horizons.
The currents that brought him to the shores of the Indian Ocean were multiple: a Jewish merchant mentioned India, and our writer’s eyes turned towards the ends of the earth; he then navigated the seasonal waterways of the Nile and Red Sea and modified his itinerary to celebrate the Jewish holidays while weaving his Arabic literary milieu and Jewish education into a unified rhetoric through puns, rhymes, and biblical citations as he detailed key stages in the passage from the Nile to the Indian Ocean. He expressed this convergence of currents with detail, humor, and anxiety in a letter sent home to Tripoli, providing testament to the complex emotions and logistical questions which Indian Ocean traders faced.

9 It is entirely possible that Fusṭāṭ was our traveler’s final destination until “Happy Eyes” suggested that he travel to India. Goitein referred to him as “the man with gladdening eyes,” עינין שרה (with a left-hand dot to distinguish sin from shin, thus sarra, not sharra). Ashur, Elbaum, Goapalakrishnan, and Rustow translate sarra as “Happy” instead of Goitein’s “gladdening,” which would require a spelling of sārra. Rustāq is a geographical term of Persian origin that refers to rural settlements, from Pahlavi rōstāg; see D. N. MacKenzie, A Concise Pahlavi Dictionary (Oxford University Press, 1971), 72, which defines rōstāg as “river-bed; district, province.” Cf. New Persian rostā: see F. Steingass, A Comprehensive Persian-English Dictionary (1892; repr. Librairie du Liban, 1972), 594: “a market-town, village … cultivated country with towns and villages.” For a discussion of the term rustāq in medieval geography, see Roy P. Mottahedeh, “Medieval Lexicography on Arabic and Persian Terms for City and Countryside,” Eurasian Studies 16, nos. 1–2 (2018): 475. Mottahedeh relies on Yāqūt al-Ḥamawī’s definition, which states that the rustāq was a larger area of cultivated land that could encompass several villages, in contrast to an urban area. The same distinction between rustāq and urban land appears in Judeo-Arabic in T-S Ar.6.1, l. 2: fī l-balad wa-fī l-rustāq. For its use in Judeo-Arabic, see also Mordechai Akiva Friedman, A Dictionary of Medieval Judeo-Arabic in the India Book Letters from the Geniza and in Other Texts (Ben Zvi Institute, 2016) [Hebrew], 864.

17 The Mamluk chronicler Ibn Taghrī Birdī provides data on the Nile levels for each year which does not suggest anything exceptional about the Nile levels in 496 AH (1103).The minimum level of the Nile (measured in late June, which was not actually its true minimum) would have been seven cubits and eight fingers, and its flood level in 496/1103 was seventeen cubits and one finger. These levels were relatively typical for the period and confirm that our merchant’s journey fits into broader patterns of Nile travel. Abū al-Maḥāsin Yūsuf Ibn Taghrī Birdī, al-Nujūm al-Zāhira fī mulūk Miṣr wa-l-Qāhira, 12 vols., (al-Muʾasasa al-miṣriyya al-ʻāmma li-l-taʾlīf wa-l-ṭabāʿa wa-l-nashr, 1963–71), 5:187.

24 Cooper, Medieval Nile, 161. He says he departed Fusṭāṭ at the end of Iyyar 4863, equivalent to early May 1103. He reports two months from Fusṭāṭ to Qūṣ, so we estimate that he arrived in Qūṣ in early July. “Some days” in the desert is not very specific, but it can be corroborated by Cooper’s estimate that this journey took between 19 and 23 days.

Constable and William Facey (Arabian Publishing, 2012), 75-77; Daniel Martin Varisco, Medieval Agriculture and Islamic Science: The Almanac of a Yemeni Sultan (University of Washington Press, 1994), 38 [English]; 58 [Arabic]; G. R. Tibbetts, Arab Navigation in the Indian Ocean before the Coming of the Portugese, being a translation of Kitāb al-fawāʾid fī uṣūl al-baḥr wa-ʾl-qawāʾid of Aḥmad b. Mājid al-Najdī (Royal Asiatic Society of Great Britain and Ireland), 372; Sulaymān al-Mahrī, al-ʿUmdat al-Mahrīya fī ẓabṭ al-ʿulūm al-baḥrīya (Majmaʿ al-lughat al-ʿarabīyya, 1970), 115-116. The annual variability of the monsoon and our own challenge in reconstructing this history means that we have a general sense of the pattern, rather than a fixed deadline for the end of the sailing season. Our calculations of the sailing seasons of the medieval Indian Ocean rely on medieval almanacs, not historical meteorology. Sailing seasons for the Indian Ocean were reported in the era of Yazdagird, an Iranian calendar. The first day of the new year was known as Nayrūz and sailing seasons would be recorded as occurring a certain number of days after Nayrūz (generally in intervals of ten). Since this calendar did not use leap days, Nayrūz receded one day for every four years of the Julian calendar: Nayrūz fell on November 15, 1488 (10 Dhū al-Ḥijja 893) according to a contemporary chronicle; while a thirteenth century chronicle records Nayrūz fell on January 8, 1271 (Lunde, 77). There is a similar discrepancy between the start of the sailing season. The damānī sailing season at the end of the southwest monsoon began 280 days after Nayrūz according to a chronicle from 1511 (al-Mahrī, 115); while according to the chronicle from 1271, this season started 230 days after Nayrūz (Varisco, 38 [English], 58 [Arabic]). This discrepancy for the start of the dāmānī season can be explained by the retrogression of the Nayrūz date: as Nayrūz receded, the beginning of the sailing season occurred more days after Nayrūz. Using these dates, we can expect the damānī season began in late August and concluded by early October. Nonetheless, these calendar issues and interannual variability present methodological challenges for determining the exact sailing season of a given year. We cannot provide a specific ‘deadline’ for the end of the sailing season from Aden to India but we expect it ended before this letter’s composition. It is possible that since the dāmānī season overlapped with the High Holidays which our Jewish writer would have preferred to celebrate on land, he attempted to set sail during the transitional season between the summer and winter monsoons (rīḥ al-qilaʿayn). During this period (roughly October and November) it was possible to sail northwest and southeast (Lunde, 77; Tibbetts, 369). Nonetheless, we do not know enough about historical monsoons or how sailors managed these calendar calculations to give an exact time frame for these seasons. The exact timing of the sailing season in 1103 was important to this novice trader’s ambitions but remains unknown to us. What we do know about his conditions comes from his own writing: he is about to cross the Indian Ocean and he is anxious about the uneven seas.

30 Maimonides echoes the ruling that if the ship touches the seafloor or riverbed it should be considered a form of land travel, which is forbidden on Shabbat. This is not a concern for Maimonides if the river or sea is at least ten handbreadths deep. Joshua Blau, ed., Teshuvot ha-Rambam, vol. 4 (Mekitze Nirdarim, 1986), 4:12–14, as cited in Herbert Davidson, “Maimonides and Samuel Ben Ali,” in Resianne Fontaine et al., eds., Studies in the History of Culture and Science: A Tribute to Gad Freudenthal (Brill, 2011), 184. Raymond Scheindlin notes in a comment on the correspondence of Judah ha-Levi that “though it was prohibited to embark or disembark on the Sabbath or a festival, a person who was already on the ship before the holy day might sail with an easy conscience.” Scheindlin, Song of the Distant Dove: Judah Halevi’s Pilgrimage (Oxford University Press, 2008), 149.

38 Our assumption that he was familiar with Arabic literary style is supported by Konrad Hirschler’s argument that this period saw an increasing popularization and textualization in urban Egypt and Syria see Konrad Hirschler, The Written Word in the Medieval Arabic Lands: A Social and Cultural History of Reading Practices (Edinburgh University Press, 2012). Kristina Richardson has also emphasized the street-level popularity of hyper-eloquent itinerant figures across the medieval Islamic world: Kristina Richardson, Roma in the Medieval Islamic World: Literacy, Culture, and Migration (London: I. B. Tauris, 2021), 97–98. This letter dates to roughly the same period as the composition of al-Ḥarīrī’s Maqāmāt which also shows a close association between punning, itinerant traders, eloquent beggars.
39 The trader’s punning in 1103 appears to be among the earliest instances of this wordplay, which is later also attested in a letter by Abraham ben Yijū. See India Traders of the Middle Ages, 710, 722.
40 T-S 8J21.10 (Goitein and Friedman, India Book, III, doc. 39), ll. 6, 9. See Goitein and Friedman, India Traders, 719–21 for a discussion of this letter. Ibid, 719n1 identifies the same pun in a work by al-Wahrānī. In another letter from Avraham ibn Yijū, T-S 12.458 (Goitein and Friedman, India Traders, III, doc. 40a, l. 5), the town’s name is also spelled as ʿadhāb. The India Book project team (see note 3) has provided us with their draft commentary where they identify this pun in two additional documents: VI, 31v (ENA 4020.25), l. 3; and VI, 32 (L-G Misc. 13), l. 9. These two letters were written by Yiṣḥaq b. Aharon Sijilmāsī to Ḥalfon b. Netanel around 1140 CE.
