āwī.7 Each physician used the medical knowledge he acquired from his teachers and the medical literature of his time; however, many of the books had been written centuries earlier, often in other parts of the world, and were later translated and copied many times in different geographical locations.8 Other books were written by court physicians, commissioned by the local ruler, especially in the Ayyubid period.9 Authors of such theoretical books were never limited in choosing the materia medica: for example, Maimonides counselled the sultan al-Afal (d. 1225) to supply the court pharmacy with the best substances possible.10 In contrast, practitioners who had to treat people from the lower socio-economic strata had to prescribe formulas based on the substances they knew and could rely on, and which were available in the vicinity and were stocked by pharmacists. Even then, the availability of the substances was not guaranteed, and sometimes practitioners had to prescribe a substitute formula based on the less expensive and tried and trusted substances at hand.11 In reality, the practical inventory of materia medica was thus smaller than the theoretical inventory, which was based upon the books that physicians had in their possession. It was only logical that some medicines and medicinal substances were used more often than others, according to price, availability, practitioners’ choices, and even local medical trends.
The main goal of this study was to learn about the practical medicinal uses of various substances by the members of the Jewish community of Cairo as a reflection of the Mediterranean Arab world as a whole. We were able to do this thanks to the Cairo Jewish community’s unique habit, based on religious law, of gathering all written documents and keeping them in the attic of their synagogue. These are the Genizah collections, whose survival is also linked to the dry climate of Old Cairo, which contributed much to the preservation of the fragments for more than a thousand years.
The Genizah collections, especially the Taylor-Schechter Collection at Cambridge University Library, which include, inter alia, various medical documents, provide a golden opportunity to assess the quantities of both the practical and theoretical inventories of the Genizah people, and to display the gap between the two. Moreover, we would like to probe the commercial cycle of physicians, patients, herbalists, pharmacists, merchants, local markets, and international trade in the areas under Islamic rule and cultural/scientific influence.
This being our objective, what can we learn about the practical uses of materia medica? How can we discover the main diseases that afflicted people in the communities under study? And finally, what were the most frequently prescribed medicines and medicinal substances in eastern medieval society?
The Genizah and Research on Medical Issues The Genizah’s many manuscripts have been studied ever since they were discovered in the late nineteenth century.12 Individual fragments have been published, catalogues written,13 and much research focusing on a wide variety of matters has yielded a wealth of articles and books. Among the main fields of study have been religious and biblical subjects, Jewish law, education, poetry, social life, trade, communal organization, and so on. The importance of the Genizah for research on medieval Mediterranean communities, supplying as it does information on almost every aspect of life, has been demonstrated by Shlomo Goitein, Moshe Gil, Menahem Ben-Sasson and others.14 Medical issues in the Genizah have, however, tended to be researched only as part of other subjects—such as the different professional classes of the Jewish community in Old Cairo. Nevertheless, a number of scholars have dealt with medical matters, including Goitein, Colin Baker, Paul Fenton, Albert Dietrich, Mark Cohen, Esti Dvorjetski, and, especially, Haskell Isaacs.15 The current study focuses on the works of Isaacs, Goitein, and others on medicine in the Genizah through a re-examination of the fragments they mention, and many dozens of new fragments identified as medical since Isaacs and Baker’s catalogue was published.16 Obviously, poring over the fragments for new interdisciplinary research will result in different outcomes from the cataloguing process conducted by Isaacs and Baker.17 Our findings reveal that not all medical fragments can be treated as a single group; they fall into different categories according to their literary style and especially their uses. Isaacs and Baker do differentiate between various kinds of fragments—letters, lists and prescriptions18—although they frequently do not classify the manuscripts correctly, for example, they describe a medical formula found in part of a book as a prescription.19 Most of the data published in their catalogue proves to be based in the theoretical medical literature, that is, medical writings copied from the well-known books of earlier medical authorities, classical (for example, Hippocrates, Galen) as well as Arab (for example, Ibn Sīnā, Ibn al-Bayār), which were copied in many different versions. The process of study and analysis of the medical fragments of the Cairo Genizah led us to devise a method of differentiating the types of information found in them.20 For example, we can now distinguish theoretical professional medical writings, written in a standard, firm and clear hand (on sheets of the same size and quality, the same number of lines per page, and margins of fixed size) from practical prescriptions, usually scrawled in a vulgar style, no longer than one or two pages, a varying number of lines, margins of various sizes, one side blank, verso inverted in relation to recto or written between the lines or in the margins of books, Bibles, on official documents, on private letters, and even on receipts.21 |
Findings We discerned five main groups of medical fragments. Firstly, medical books were copied by professional copyists from works written by physicians and pharmacists. These were classics, of Christian, Muslim, as well as Jewish origin. So far 1360 fragments of medical books have been identified in the Taylor-Schechter Collection. The books are in Arabic (740), Judaeo-Arabic (470), and Hebrew (150). Isaacs and Baker identified 35 titles. Since then about 15 more titles have been identified by Efraim Lev and Leigh Chipman, and the work is still in progress.22 Of the books already identified, roughly one-third were written by pagan classical authorities, including Galen and Hippocrates. Another third were written by Muslim writers, including Sābūr Ibn Sahl,23 Ibn Sīnā, al-Rāzī, Ibn al-Bayār, and ‘Alī Ibn ‘Īsā.24 The remainder are by Jewish physicians, members of the Cairo Jewish community, such as al-Kūhīn al-‘Aar, Daud Ibn Abī al-Bayān,25 and Maimonides. Maimonides wrote abridged versions of Galen’s works De temperamentis and De alimentorum facultatibus.26 These texts are preserved only thanks to the Genizah.27 Other sources for the reconstruction of the “Genizah medical library” are lists of books owned by private individuals and sold after their deaths.28 Al-Kūhīn al-‘Aar’s Minhāj al-dukkān was considered in the past—and by scholars today—to be one of the most popular and useful pharmacopoeias of medieval medicine.29 Despite its practical character, the book contains much theoretical material (see Figure 1). | Figure 1A page from Abū al-Munā al-Kūhīn al-‘Aar’s Minhāj al-dukkān fī al-adwiya al-nāfi‘a lil-insān (The Shop Guide, or, How to run the (more ...) |
Secondly, come the personal notebooks of medical practitioners. Fifty such notebooks have been identified. They contain medical theories, descriptions of methods of healing, and selected prescriptions which were chosen and then copied for their own use by medical students or practitioners from books and famous physicians whom they worked with or under.30 From our research into these notebooks, we concluded that most concentrate on one area of medicine, such as ophthalmology, gynaecology, or dentistry (see Figure 2), and only a minority contain recipes for treatment of a variety of complaints.31 These notebooks give us a preliminary idea of the most prevalent diseases, and of the medical interests shared by practitioners, patients and other members of the community. It should be mentioned here that diseases are known today as (at least partly) social constructs. Contemporary concerns regarding health and diseases played a role in shaping the medical corpus, including practical prescription. | Figure 2 A fragment of a notebook on dentistry (T-S. Or.1080.7.17). |
Thirdly, the letters of medical practitioners and patients, and those sent to medical authorities or institutions provide additional information. Several letters from Maimonides were revealed, in which he gives medical advice and mentions medicinal substances among other issues.32 We consider these particular letters as types of prescription, and so contributory evidence on the practical use of these substances. Another example is a letter from Maimonides in which he recommends drinking two cups of milk a day as a treatment, although, unfortunately, he does not specify the complaint.33 Fourthly, there are prescriptions written by physicians after seeing a patient; the recipe (formula) would be made up by a pharmacist. A total of 141 unique original prescriptions were found in the Taylor-Schechter Genizah Collection; of these, 40 were more or less complete.34 A few more were discovered in other collections. In most cases these are written in Arabic script (92) and Arabic written in Hebrew script (Judaeo-Arabic) (47), the most widely used languages and dialects in the daily life of medieval Cairo. Very rarely Hebrew (1) or Judaeo-Persian (1) is found. In a few cases the prescription is written in Judaeo-Arabic but the benedictions that open and close it are written in Arabic script (see Figure 3).35 In one case, the same formula is written in Judaeo-Arabic on one side of the sheet and in Arabic on the other.36 In another, two similar versions of the same formula, written in Arabic and headed ma’jūn hibat allāh, are found on the same side of a fragment.37 The handwriting is usually sloppy and unclear. A few prescriptions were copied identically, others with changes, from famous books such as Minhāj al-dukkān or Dustūr al-Bīmāristanī. 38 Most of these prescriptions were written on one page, usually on one side of a sheet of paper and very rarely on vellum. They were often written on reused paper; at times in the margin or between the lines of other documents or even books.39 | Figure 3 Prescription for a recipe written in Judaeo-Arabic, opening and closing with benedictions in Arabic (T-S Ar.30.305). |
The most important and interesting information is undoubtedly to be found in the prescriptions. They reflect the medical reality that existed in Cairo, which at times corresponds with that found in books. A unique aspect of the information that emerges from the prescriptions is their originality. Unlike the information derived from books, which are usually copied from classical or contemporary medical sources, the prescriptions are clear-cut primary evidence of the medicinal substances used, and of the medical conditions that afflicted the members of the community, and the ways they were treated. There are 242 medicinal substances mentioned in the prescriptions, of which 194 are of plant origin (80.1 per cent), 20 are of animal origin (8.3 per cent), and the remaining 28 are inorganic (11.6 per cent). We consider the prescriptions clear-cut evidence of the use of these substances for medicinal purposes and an important element of medical knowledge in its practical form.40 Prescriptions can teach us about the prevailing diseases and symptoms that members of the community suffered from, although in most cases neither the symptoms nor the patient’s name appear on the prescription. Very few prescriptions have been published so far. Goitein discusses one on how to become stout; and publishes the translation of another; it is not clear for what condition it was prescribed.41 Still, analysis of the prescriptions and some of the notebooks with the help of contemporary pharmacopoeias shows eye diseases to have been the most prevalent ailments. Many dozen fragments concerned with ophthalmology deriving from many medical books dealing with eye diseases (especially ‘Alī Ibn ‘Īsā’s Tadhkirat al-kaālīn) are further evidence of this.42 Other ailments include skin diseases, headaches, fevers, internal diseases (liver), intestinal problems, and haemorrhoids, as well as urinary trouble, ulcers, swellings, cough, and gynaecological illnesses. A few of the formulas were copied from theoretical medical literary sources. These are mainly works such as al-Kūhīn al-‘Aār’s Minhāj al-dukkān or Ibn Abī al-Bayān’s Dustūr al-bīmāristānī.43 Finally, there are the lists of materia medica. These may be of various origins: inventories of pharmacies compiled for establishing or dissolving partnerships, for commercial orders, or for tax purposes; pharmacists’ invoices and order forms for substances, especially those of wholesalers sent to retailers, or of pharmacists sent to wholesalers. These are among the best sources for the study of practical materia medica and the reconstruction of the community’s inventory of practical materia medica. Goitein, for example, draws attention to one invoice for two consignments, one of 54 items, another of 34. The drugs listed are known from other sources, but in this case all were carried at the same time by one retailer; the fragments mention weights and prices as well (see Figure 4).44 Invoices to individuals are common, and they teach us about transactions, payments, and medicinal substances used at that time. Some invoices note quantities and prices, others show only the prices.45 | Figure 4 List of simples and their quantities, written in Judaeo-Arabic, including weights or prices in Coptic numerals (T-S Ar.30.274). |
In general, the 71 original materia medica lists found in the Genizah lack any headings that might explain their uses. However, since they are different from merchants’ letters dealing with trade in materia medica and give no instructions for the use or preparation of formulas (as is usually found in prescriptions), they were identified as materia medica lists. Some of these lists are written in Judaeo-Arabic (26), but the vast majority are in Arabic (45), none is in Hebrew. In some cases they appear as rows with written quantities, in others they are written as long columns, sometimes on very narrow and long or large sheets of paper.46 Occasionally the quantities are in Arabic words, at other times in Hebrew script, in a few cases in Coptic numerals.47 These lists were apparently used by pharmacists for professional and business purposes as inventories of materia medica, records, orders, or even receipts. Orders to the sharābī (sellers of potions) were also found and studied.48 The lists point directly to the existing trade in these substances and the place they occupied on the shelves of the pharmacies found in the lanes and alleys of the Jewish quarter of Cairo. However, they vary considerably in size. The average number of substances on the short lists (up to 10 substances) is 6, and on the long ones (more than 10 substances) it is 26. The longest list contains 63 identified substances. Two hundred and six medicinal substances are mentioned in all the lists, of which 167 (81 per cent) are of plant origin, 16 are of animal origin (7.8 per cent), and the remaining 23 are inorganic (11.2 per cent).49 In addition to the lists, merchants’ letters contain excellent information on other aspects of this trade: they mention drugs’ names and their origin, and we can learn about routes and other aspects of the drug trade of that era, for example, between Cairo and Alexandria.50 Also, there is information on imports of drugs to port cities, for example to the Rif and Cairo.51 One such fragment describing the trade in medicinal substances between India and other countries in the Far East and Egypt is discussed by Dietrich.52 A large number of the substances mentioned in merchants’ letters were also used by members of this medieval society as foodstuffs, spices, and condiments, and in industries such as tanning, dyeing, etc. However, these documents were not used as main sources for our research since they do not have a direct relevance for medicinal uses. |
Discussion This section of the paper has assessed the information contained in the Genizah collections in relation to the medicine practised in the Mediterranean Arab world in the medieval period, and the contribution of the Arabs to medicine and pharmacy, mainly as regards medicinal substances.53 We also consider the theoretical inventory of materia medica, which is based on medieval medical books found in the Genizah. The presentation, analysis, and comparison of these two types of knowledge are the core of this article, although other related subjects are addressed too. As we have seen, the advantages of the prescriptions and personal letters lie in bringing together authentic information which reflects the reality of practice; in particular the names of common diseases and drugs in the medieval period. On the other hand, it is possible and even necessary to confront and verify our conclusions with the theoretical medical literature written in the same period regarding specific diseases. We can presume that most of these theoretical books were written to address contemporary Egyptian health needs. The books cover medical issues such as eye diseases, haemorrhoids, sexual diseases, asthma, etc. In this sense, Maimonides’s texts reflect a representative model; according to his testimony, he wrote these books for the Ayyubid rulers (1187–1250), sometimes for the needs of the public, as in the case of his book on poisons,54 or for the personal requirements of the ruler. In both cases, these books reflect medical issues among the influential upper socio-economic strata. In the case of the prescriptions, we can presume that they partly reflect the experiences of the lower strata as well. These texts, therefore, open a new window for modern scholars, through which they can widen their knowledge regarding the diseases from which the Egyptian medieval population suffered and the drugs they used to heal themselves. Inventory of Theoretical Materia Medica of the Medieval Genizah People In addition to the four types of practical text discussed above, the Cairo Genizah collections contain extensive theoretical medical writings. The nature of these writings clearly distinguishes them from the practice-based texts. Thus the sampled inventory of theoretical materia medica mentioned in fragments of medical books found in the Cairo Genizah consists of 414 substances. 55 Of these, 310 are of plant origin (74.8 per cent), 35 are of animal origin (8.5 per cent), and 69 are of inorganic origin (16.7 per cent). The number of substances of animal origin is proportionately much the same as in the prescriptions, but some are exotic and would be very hard to obtain, for example, elephant bile, wolf gall, hyena bile, crow’s gall, bear bile, lion bile, medical skink, and rhinoceros fat. For the sake of comparison and context, several other theoretical inventories of materia medica have been reconstructed, studied, and analysed on the basis of books written by classical as well as medieval medical authorities. The sources for these are: TG—Theoretical Genizah (based on medical literature found in Cairo Genizah);56 ML—medieval Levant (based on both medieval medical literature and commercial sources); 57 MG—Maimonides (thirteenth century AD; based on his translated book);58 AK—al-Kindī (tenth century AD; based on his translated book);59 DI—Dioscorides (first century AD; based on his translated book);60 and HP—Hippocrates (fourth century BC; based on Riddle’s analysis).61 It is clear from these sources (see Table 1) that theoretical inventories consisted of a fairly large number of substances, between 250 and 864. The theoretical inventory of the Genizah people, consisting of 414 substances, lies more or less in the middle. | Table 1 Division by substance origin of historical theoretical medicinal inventories |
Inventory of Practical Materia Medica of the Medieval Genizah People As noted, the reconstructed inventory of practical materia medica is based on medicinal substances that feature in prescriptions and letters written by medical practitioners of the Jewish community of Cairo, and recorded in materia medica lists compiled by pharmacists, drug sellers, and drug traders. These medicinal substances were identified, studied, arranged in a database and analysed. The inventory comprises 278 substances, of which 223 (80.2 per cent), the great majority, are of plant origin; 31 substances (11.2 per cent) are of inorganic origin, and 24 (8.6 per cent) are of animal origin. A further concern was to evaluate and analyse the data and subdivisions of the reconstructed inventory of the Genizah people by comparison with present-day traditional practical inventories of various ethnic groups, as well as traditional societies with a similar social background and of the same geographical area, namely the Middle East and North Africa. These data (see Table 2) were taken from surveys of markets in Egypt, Israel, Jordan and Syria, and from inventories resulting from studies of medicinal substances used by Jewish and Muslim ethnic groups:62 inventory of practical medieval usage as evidenced by the Genizah (PG);63 Cairo markets, nineteenth to twentieth century (EG);64 survey of markets in Israel (MIS);65 survey of markets in Syria (SY);66 survey of markets in Jordan (JO);67 survey of markets in Morocco (MO);68 Yemeni Jews in Israel (YJ);69 Iraqi Jews in Israel (IJ);70 and Bedouins in southern Israel (Negev) (NB).71 Table 2 clearly shows that the size of the Genizah’s practical materia medica inventory (278 substances) is close to the average size (285) of the other inventories that appear in the table. The division of the contents of traditional inventories of present-day Middle Eastern societies and ethnic groups by substance origin is also similar, in absolute figures and percentages. | Table 2 Division by origin of traditional medicinal substance inventories of some countries and Jewish and Muslim ethnic groups |

Conclusions Three main conclusions emerge from our findings and analysis, and we present them here separately according to their logical sequence. Diagram A attempts graphically to present the complex medieval web of medicinal substances. It displays various factors, their relationships, and their effect on the theoretical and practical inventory of materia medica in the Jewish community of Cairo as an example of medieval society. The continuous lines represent the transfer of materia medica or knowledge from one factor to the other. The broken lines represent the control of the hisba (market inspection). Actual demand is depicted in the centre and was generated by the market, firstly through the customers (for example, patients) and affected mainly the practical inventory of materia medica. On the other hand, at the top of the diagram, the theoretical inventory lies within the category of textual medical and pharmacological knowledge. | Diagram A Influential factors on the inventory of the practical medieval materia medica of Mediterranean society. |
The Gap between the Theoretical and Practical Materia Medica Inventories of the Medieval Genizah People In the introduction we presented several questions and hypotheses that were before us while we conducted our research. The first research question was, is there a gap between theoretical and practical medicinal substances, and the second was, what is the ratio of the two groups, and what is the size of the gap? The hypothesis was that the Cairo Genizah documents would help us detect such a gap and even measure it. It appears very clear that the theoretical inventory of the Genizah people was much larger than the practical one. Therefore, regarding the first question we can definitely answer that a gap of 136 substances exists, of which 87 are of plant origin (64 per cent), 38 of animal origin (27.9 per cent) and 11 are of inorganic origin (8.1 per cent). This gap separates the theoretical list (mentioned in books), consisting of 414 substances, from the practical one (mentioned in prescriptions, letters, and lists of materia medica) consisting of 278 substances.72 This gap is especially conspicuous considering that a few of the substances mentioned in the practical literature are mentioned frequently in the medieval theoretical medical literature on the one hand,73 and are used intensively in contemporary traditional medicine on the other. These particular substances can be found in Middle Eastern and North African markets to the present day, for example, Jew’s stone, nightshade, lupin, and sweet lime. Lupin and sweet lime were grown and used as foods in Egypt itself. Regarding the second question, the ratio between the two groups is not easily determined. The numerical answer is that the gap consists of more than one-third (33.8 per cent) of the total number of materia medica mentioned in books, prescriptions, and materia medica lists. However, this picture is very complex and contingent on many factors that sustain each other in a delicate and interesting web. The different inducing factors are the patients, their families, local healers, learned physicians, pharmacists, drug sellers, herbalists, market supervisors, traders, wholesalers, and professional medical literature. Remnants of such a web, on a smaller scale, can be found and studied in the traditional medicine system that still exists in some Arab countries. We discovered this phenomenon when we studied the inventory of substances of traditional medicine in Israel.74 It became clearer through another ethno-pharmacological survey conducted in the kingdom of Jordan, as a result of which we tried to explain diagramatically the geographical relations of dealers in Jordan, other Arab countries, and Israel.75 A written illustration of the power of one of these factors emerges from the citation from Maimonides’ book (given in the introduction). He fervently recommends to the Muslim ruler al-Afal that the court pharmacy be supplied with the best substances possible, thereby enlarging the practical inventory of materia medica of the medieval Egyptian court according to the medical literature (theoretical inventory).76 The theoretical medical knowledge derived from the medical books was undoubtedly the firmest textual foundation for the practical treatment applications of contemporary practitioners, but clearly they used only a fraction of it. The twenty most frequently mentioned, hence used, substances are presented in Table 3. This list can teach us about market demands, trade, economy, and practical medical trends. All these substances are of plant origin, apart from salt and honey. A few may have been of local provenance, such as gum arabic and sugar, while others were brought from the Levant (almonds, rose, endive). Many others were obviously imported into Egypt from south-east Asia (pepper, myrobalan, camphor, spikenard) and others from the western Mediterranean (saffron, lentisk). | Table 3 The twenty medicinal substances most frequently used by members of the Jewish community of old Cairo according to the Genizah fragments |
The reconstructed inventory of practical materia medica points directly to the existing trade in these substances and the place they occupied on the shelves of the pharmacies located in the Jewish quarter of Cairo.77 Egypt was one of the production centres of substances such as alum, cassia, flax, gum arabic, purging cassia, and sugar, but these are a minority in the inventory. Here, however, we have chosen to set out the broad spectrum of medicinal substances traded and used in Egypt. Some were imported from India and south-east Asia, for example, cubeb, cinnamon, clove, galingale, indigo, pepper, myrobalan, camphor, and spikenard.78 Others came from Yemen (alum, mineral mummy, screw pine), Arabia (frankincense, balm of Gilead, sweet-flag), North Africa (coral, saffron, olive oil, soap, honey and wax), Sicily (alum, coral, lead, sulphur, silk, cheese), Crete (cheese, dodder of thyme), Europe (cheese, coral, honey, saffron, lentisk, silk, copper, iron, lead, mercury, earth, silver), and the Levant (asphalt, almonds, rose, dried fruits, endive, gull nuts, scammony, olive oil, soap, sumac, wax). Yet other substances were exported from Egypt to south-east Asia (dodder of thyme, saffron), North Africa (flax, different spices), Sicily (flax, indigo, pepper, cinnamon, clove, sal ammoniac), Europe (alum, pepper, cinnamon, clove, sugar), and the Levant (safflower, meadow saffron, henna, purging cassia, mummy, salep, aniseed). A study of similar issues in the medieval Levant showed that out of the 268 medicinal substances recorded as being used medicinally, 99 were traded. Twenty-two substances, mainly spices from Asia, were transhipped through the Levant (to Europe), 16 others were imported only, and 61 were exported, mainly to Egypt (33) and Europe (25). Among the exports to Egypt were almonds, bean trefoil, berberry, bugloss, common wormwood, dog rose, fig, grape vine, honey, hyssop, Jew’s stone, mung bean, oak gall, olive oil, pear, peony, pistachio nuts, pistacio resin, quince, saffron, stone pine, styrax, sumac, tragacanth, wax, and white melilot.79 The widespread commerce in medicinal substances among the different trading centres in the medieval period will be discussed in detail elsewhere.80 But the first signs of such activities may be seen in a book attributed to al-Jāhiz (tenth century),81 and in the story of the Radhanite merchants, who originated in the north-eastern part of Baghdad. Their commercial activity is mentioned by Arab geographers such as Ibn al-Faqīh, and according to these historical sources the Radhanites had four main trading routes: two maritime and two overland. In fact, this was an international network of Jewish merchants with trading ties all across the Islamic empire. Its agents were sent everywhere, from al-Andalus in the extreme west to China in the farthermost east.82 A remarkable conclusion that emerges from perusal of the complete Levantine list is that at least some substances (cloves, cassia, purging cassia, sugar, rhubarb, mace, musk) were introduced to the Middle East, and later to Europe, by the Muslims.83 This may be considered as significant evidence of the contribution of the Muslims to pharmacy and medicine in general, and to the enrichment of the classical inventory of materia medica in particular.84 It is interesting, though, that trade in several of the above-mentioned substances was in the hands of members of the Jewish community of medieval Cairo, who traded with India, Sicily, Syria, North Africa, and other ports and cities.85 |
