What Were Some of the Advances in Technology Education Literature and the Arts

Ottoman Contributions to Science and Technology

The Ottoman contribution to science and engineering science during their vi hundred yr rule is across measure. This article is a brief outline of just some of the Ottoman scientific activities and related institutions that brought almost the revival of culture, science, and learning in culture throughout the Islamic world and beyond. To instantiate the Ottoman scientific contributions, the writer focuses on two meaning examples from astronomy and geography in the 16th century: the foundation of Istanbul Observatory and Taqi Al-Din's achievements therein, map making and mapmakers such as the famous sailors Piri Reis, Saydi Ali Reis and Macar Ali Reis.

1. Setting the stage

In its history and evolution, the innovative features of Ottoman scientific discipline are obvious and various. Whilst the older Islamic centres of science and civilisation influenced initially Ottoman scientific tradition, information technology quickly reached a point where it could itself influence these former centres and serve as an instance to them.

The great changes in the scientific and educational life of the Ottomans were achieved over an extensive period of time. Consequently, information technology is hard to connect the radical changes in Ottoman history to specific events or to starting time from a certain appointment. In general, "erstwhile and new" existed side past side. To substantiate such a merits, focus will be laid in this section on the germination and evolution of the classical Ottoman scientific tradition that was based on the Islamic classical scientific tradition, including the heritage of the Seljuks and other Muslim and Turkish states [1].

The Ottoman Empire was established as a small principality at the turn of the 14^th century and gradually expanded into the Byzantine Empire and other Muslim and non-Muslim states. Its authorization reached its highest point in the sixteen^th century, and it became the well-nigh powerful state of the world. The Empire extended from Cardinal Europe to the Indian Ocean and lasted for many centuries by keeping the residual of power with modern Europe [2].

Scientific activities in the Ottoman state emerged and developed in Anatolian cities from the scientific legacy and institutions of the pre-Ottoman Seljuk menstruation and benefited from the activities of scholars who came from Egypt, Syrian arab republic, Islamic republic of iran, and Turkestan—that is, from the substantial scientific and cultural centres of the time. Alongside the old centres of Islamic civilization, new centres, such as Bursa, Edirne, Istanbul, Amasya, Skopje, and Sarajevo flourished during to Ottoman period. The developments of this period form the heritage that constitutes the cultural identity and scientific legacy of present-day Turkey, likewise as an of import part of the intellectual history of several Middle Eastern, Due north African, and Balkan countries. The Ottomans too benefited greatly from their non-Muslim subjects and European neighbours, and provided very favourable working conditions for scientists from many different fields, including medicine, astronomy, and mathematics, by inviting them to conduct their studies at the important centres of science and culture in the Islamic world [3]. Engaging the services of scientists and artists from either the w or the eastward every bit needed, without regard to religion or nationality, was an established and advantageous practice in the Ottoman Empire [iv].

During the classical menses, Ottoman scientists and scholars showed remarkable success in developing scientific discipline and were able to produce many works in various branches. This paper provides an overview, with examples, of the formation and development of Ottoman science and scientific activities in the fields of geography and astronomy.

From as far back equally the time of the Prophet, nosotros know that Muslims had needed astronomy for the determination of times, an of import factor in religious duties, and geography to find the direction of the Ka'ba. The precise calculation of the prayer times, as well every bit of the offset and the end of the daily fast in the month of Ramadan, fell naturally within the domain of the astronomer. It is true that for the times of regular prayers, for example, Muslims were given judge directions and were allowed some latitude; simple rules apropos these matters could be institute in the Traditions. From the very beginning of Islam, Muslim scholars had to work on these ii subjects under very strict rules. Due to closeness of the fields, most of the Muslim scholars had a deep knowledge of both sciences and they produced a considerable number of books.

ii. Astronomy

Astronomical studies in the Islamic culture started in the very early on days. Observations of the sun and the moon and the calculation of the prayer times required precision. The observatory was one of the most highly developed institutions of science and learning in Islam and one of the high-water marks of the Muslim culture. There is no dubiousness that the observatory, as a specialized scientific establishment, owes a swell deal to Islam. It may very reasonably be claimed that it was in Islam that the observatory, as a specialized institution with an official and legal status and with a fixed location where observation and other work on stellar bodies was systematically carried out through the cooperation of several scientists, first came into beingness.

Already early in the 9^th century, the Caliph Al-Ma'mun initiated the tradition of founding observatories in Islam, past founding ii major simply very short-lived observatories, the Shammasiya in Baghdad and Qasiyun in Damascus. There are eight other examples of the building of total-fledged and elaborate official land observatories in the Islamic realm up to the 17^th century.

The Maragha Observatory, founded in 1259 under the patronage of Hulagu, was one of the near elaborate institutions of its kind and the scene of important work. Prince Ulugh Bey built another gigantic observatory in Samarqand in 1420, and finally the Tophane Observatory in Istanbul was founded by Murad III in 1577.

2.1. Istanbul Observatory

In the Ottoman civilization, scientific institutions, in the field of astronomy, included the main astronomer's part (munajjimbashi), the muvaqqithānedue south and the Istanbul Observatory. Though one can find original and translated works in the fields of astronomy and astrology from the early on catamenia, the first calendrical works but began during the time of Sultan Murad Two (1421-1451). These calendars were prepared as palace almanacs and we have no idea about the authors [5]. They continued the classical Islamic astronomical tradition in this field, and combined the traditions of both the Samarkand and Maragha astronomy schools of astronomy in their works. Ulug Bey's Zīj, which was prepared in the Samarkand observatory, became a very significant manual for Ottoman astronomers and astrologers [6].

The Ottomans had well organized astronomical institutions such every bit the mail of Chief-astronomer (munajjimbashilik) and fourth dimension keeping houses (muwaqqithānas). In the Ottoman palace administration, the person in charge of directing the astronomers was chosen munajjimbashi, that is Chief Astronomer. The position of Chief Astronomer was established sometime between the late 15^th and early 16^th centuries. The Chief Astronomer's most important duty was the preparation of annual calendars. They were responsible for determining the beginning of fasting times (imsāqiya) before the month of Ramadan and preparing horoscopes (zāyija) and astronomical tables (zījs) for the palace people and prominent officials.

The timekeeper's offices (muvaqqithānes) were public buildings located in the courtyards of mosques or masjids in nigh every boondocks. They were widely built by the Ottomans particularly later the conquest of Istanbul. They were administered by the foundation (waqf) of the complex (külliye) and the people who worked in the muvaqqithānes were named muvaqqit, meaning the person who kept the time, peculiarly for the times of prayer.

In improver to other science related institutions, the observatory founded in Istanbul was administered by the chief astronomer Taqī al-Dīn al-Rasid (d. 1585). The starting time Ottoman observatory was also the last big observatory of the Islamic Culture. With the support of Sultan Murad 3, he started the construction of the Istanbul observatory. As well as using the existing instruments of ascertainment, Taqī al-Dīn invented new ones in order to determine the equinoxes. He also developed and used gravity and spring driven mechanical clocks and invented a vi-cylinder pump (engine) for raising water in a continuous manner [7]. In add-on, he wrote more than thirty books in mathematics, astronomy, mechanics, and medicine.

Taqi al-Din, who was born in Damascus in 1526, worked for a fourth dimension every bit a qadīi and a teacher after completing his education in Damascus and Egypt. During his time in Egypt and Damascus, he produced some important works in the fields of astronomy and mathematics. In 1570, he came to Istanbul from Cairo, and one twelvemonth later (1571-2) was appointed Chief Astronomer (Munajjimbashi) on the death of the Main Astronomer Mustafa b. Ali al-Muwaqqit. Taqi al-Din maintained close relationships with many of import members of the ulemā (scholars) and statesmen, primary among whom was Hoca Sādeddin, and was presented to Sultan Murad by the M Vizier Sokullu Mehmed Pasha [8].

Taqi al-Din informed Sultan Murad, who had an interest in astronomy and astrology, that the Ulug Beg's Astronomical Tables contained certain observational errors, resulting in errors in the calculations based on those tables. Taqi al-Din indicated that these errors could exist corrected if new observations were made and proposed that an observatory be built in Istanbul for that purpose. Sultan Murad was very pleased to exist the patron of the start observatory in Istanbul and asked that construction begin immediately. He also provided all the financial assistance required for the project. In the meantime, Taqi al-Din pursued his studies at the Galata Belfry, and connected them in 1577, at the partially completed new observatory chosen Dār al-Rasad al-Jadīd (the New Observatory).

The observatory, consisting of two separate buildings, i big and ane small, was constructed at a location in the higher office of Tophane in Istanbul. Taqi al-Din had the instruments used in the old Islamic observatories reproduced with smashing care. In add-on, he invented some new instruments, which were used for observational purposes for the starting time time. The observatory had a staff of xvi people: eight "observers" (rāsid), iv clerks, and four assistants [9].

The observatory was designed to provide for the needs of the astronomers and included a library largely consisting of books on astronomy and mathematics. This establishment was conceived every bit ane of the largest observatories in the Islamic world and was completed in 1579. It was comparable to Tycho Brahe's (1546-1601) Uranienborg observatory built in 1576 [10]. In addition, at that place is a striking similarity between the instruments of Tycho Brahe and those of Taqi al-Din merely those of Taqi al-Din were of superior quality [11]. When compared with those of his contemporary Danish astronomer, Taqi al-Din's observations are more precise.

In Taqi al-Din's astronomical tables, called the Sidratu Muntaha'l-Afkār fī Malakut al-Falak al-Davvār (Lotus of Culmination of Thoughts in the Kingdom of Rotating Spheres), Taqi al-Din states that he started astronomical activities in Istanbul with 15 assistants in 1573 [12]. The observatory continued to role until 22 January 1580, the date of its devastation. Religious arguments were put along to justify this action, but information technology was really rooted in certain internal political struggles [thirteen].

ii.2. New observational instruments of Taqi al-Din

Taqi al-Din invented new observational instruments that were added to those already in employ for observation in the Islamic world. Among the instruments invented by Taqi al-Din in the observatory were the following:

• The Sextant (mushabbaha bi-'l manātiq): used to measure the distances between the stars. Taqi al-Din'southward mushabbaha bi'fifty manātiq and Tycho Brahe's sextant should exist considered amongst the great achievements of the 16^th century astronomy. A mushabbaha bi-50 manātiq is equanimous of 3 rulers. Ii of them are attached as the rulers of the triquetrum. An arc is attached to the terminate of one of the rulers. Taqi al-Din made this instrument to notice the radius of Venus that was mentioned in the X^th book of the Almagest [14].

• The instrument with cords (Dhāt al-awtar): designates the spring and autumn equinoxes. Some astronomers set upward a ring, which was not divided, parallel to the equator to designate this. The instrument was equanimous of a base in the grade of a rectangle and iv columns. The two columns were assail this base so that a string was stretched between them. One of them was equal to the cosine of the latitude of the country and the other to the sine. A hole was made on each of these parts according to this proportion. A rope was hung from these holes with a plumb [15].

• The astronomical clock: Taqi al-Din used a mechanical clock, which he made himself for his observations, and a wooden wall dial, which he set up in the observatory. He wrote in The Astronomical Instruments for the Emperor'southward Table: "The ninth instrument is an astronomical clock. The post-obit argument is recorded from Ptolemy: 'I would have been able to establish a great regularity in method if I was able to measure the time precisely.' Now Taqi al-Din planned, with the assist of God, the astronomical clock by the command of the Sultan, God perpetuates his ruling days. Thus, he was able to practice what Ptolemy had failed to do." Taqi al-Din says in Sidrat al-muntahā: "we built a mechanical clock with a punch showing the hours, minutes and seconds and we divided every minute into five seconds." This is a more precise clock than clocks used previously and is, equally a result, considered to be one of the most of import sixteen^th century developments in practical astronomy [16].

When we compare the instruments which Taqi al-Din used in his observatory with those used past Tycho Brahe, they are more often than not similar, but some of Taqi al-Din's are larger and more precise. Both, for example, used a landscape quadrant (Libna) for the observations of the declinations of the lord's day and the stars. It is said that Taqi al-Din preferred the mural quadrant to the Fakhri sextant (Suds-i Fakhrī) and ii rings used past previous astronomers. Taqi al-Din'due south quadrant was composed of two contumely quadrants with a radius of vi meters; it was placed on a wall and erected on the height. Tycho Brahe'due south similar musical instrument was merely two meters in diameter [17].

In his piece of work, Taqi al-Din integrated ii traditions of astronomy, those of Damascus and Samarkand. His first task at the observatory was to correct the Zīj book (Astronomical Table) of Ulugh Beg. He also undertook diverse observations of eclipses of the sun and the moon. The comet that was present in the skies of Istanbul for ane calendar month during September 1578 was observed mean solar day and night and the results of the observations were presented to the sultan. As a result of the new methods he developed and the equipment he invented, Taqi al-Din was able to approach his observations in an innovative style and produce novel solutions to astronomical problems. He too substituted the use of a decimally based organization for a sexagesimal ane and prepared trigonometric tables based on decimal fractions. He determined the ecliptic degree as 23° 28′ forty″, which is very shut to the current value of 23° 27′. He used a new method in calculating solar parameters. He determined that the magnitude of the almanac motion of the sun's apogee was 63 seconds. Because that the value known today is 61 seconds, the method he used appears to have been more than precise than that of Copernicus (24 seconds) and Tycho Brahe (45 seconds). Taqi al-Din besides wrote the showtime Ottoman volume on automatic machines, titled el-Turuq al-Saniyya fi'l-ālāt al-rūhāniyya [18].

The observatory was witness to a peachy deal of activeness inside a short menstruation of fourth dimension. Observations undertaken there were nerveless in the above mentioned treatise Sidratu Muntahā'l-Afkār fī Malakūt al-Falak al-Davvār.

2.3. Mustafa bin Ali Al-Muwaqqit

Mustafa b. Ali al-Muwaqqit al-Salīmī was another essential Ottoman polymath scholar [19]. He was well-known in the 2nd half of the 16^th century as an astronomer, mathematician, geographer, clock-maker (sa'atji) and muwaqqit (timekeeper). He made valuable contributions in the fields of astronomy and geography, producing many books of which those on making and using astronomical instruments are particularly important. These books were used as textbooks in madrasas, and some of them were copied until the middle of the nineteen^thursday century.

Figure 4: The figure of astronomical clock. Source: Ālāt al-rasadiya li-zīj al-shāhinshāhiyya (T), Library of the Topkapi Palace Museum, Hazine 452, fol. 16a.

He was initially timekeeper at the Yavuz Selim Mosque in Istanbul and later became the Main Astronomer (munajjimbashi) for ten years. He took astronomy courses and became muwaqqit at the Sultan Selim Mosque Muwaqqithana. He wrote most of his works while property this post. He invented a new instrument for astronomical ascertainment called the "rub-i āfākī" (horizontal quadrant).

There are 24 works which are definitely known to take been written past him; three in Arabic, the rest is in Turkish. By writing in the Turkish language nearly astronomical matters, he was aiming to make astronomical works accessible in this language who was condign the scientific language of the Ottoman Empire. He also produced new and original solutions to astronomical problems. Therefore, his ideas became widely diffused amid astronomers, muwaqqits and other educated people. In particular, his volume explaining astronomical instruments was very popular amid those interested in astronomy. In improver to astronomy, he also wrote three treatises of geography: Hallu Dā'irati Mu'addil al-Nahār, I'lam al-'Ibād fī A'lām al-Bilād I'lām al-'Ibād fī A'lām al-Bilād and Kifayāt al-Wakt li Ma'rifat al-Dā'ir wa Fazlihī wa al-Samt [20].

3. Geography

Equally in the field of astronomy, the Ottomans continued the classical tradition in the field of geography. The Ottomans needed geographical cognition in order to decide the borders of their continuously expanding territory and to institute command over military and commercial activities. They fabricated employ of both the geographical works of previous Muslim geographers and works of European origin. By calculation their ain observations, Ottoman geographers also produced original cloth [21]. The Samarkand school of geography and astronomy provided the primary sources for the Ottoman's noesis of geography, map-making and related fields. From the 16^thursday century onwards, Pīrī Reis, Matrakci Nasuh, Saydī Ali Celebi and other scholars produced noteworthy geographical works.

3.1. Pīrī Reīs

The almost prominent Ottoman geographer is Muhiddin Pīrī Reīs (d. 962 A.H./1554 C.E.) who besides produced original works in the fields of marine geography and navigation at the courtroom of Selim I and Suleyman the Magnificent. He was interested in the scientific discipline of cartography and completed a map of the world in 1513 C.E. This map is office of the large scale world map prepared in two parts on a gazelle hide, of which only the western part is preserved. Information technology was fatigued based on both his rich and detailed drafts and European maps, including Columbus' map of America. This was the first Ottoman map which included preliminary information about the New Globe depicts southwestern Europe, northwestern Africa, southeastern and Key America. The map has the shape of a "portland" type of map which does not incorporate latitudinal and longitudinal lines, but includes coastlines and islands and serves to familiarize one with the various regions of the world.

Pīrī Reīs also drew a 2d globe map in 1528 C.Eastward. which he presented to Süleyman the Magnificent. But the portion depicting the western hemisphere survives. Information technology is in colour and has ornamental figures on the margins with explanatory notes. The extant portion shows the northern part of the Atlantic Ocean and the newly discovered regions of Due north and Central America. Information technology shows iv current of air roses and the Tropic of Cancer, which was non shown in his first map of the globe, appears on this map. The scales used in the second map are larger than the outset. The drawing of the coastlines shows a great improvement in technique and also bears a shut resemblance to the modern conception of these areas. The stony and rocky sections are given special care.

Pīrī Reis also wrote a book on marine geography entitled Kitāb-i Bahriye (Book of the Sea, 1521). In this work, he presents drawings and maps of the cities on the Mediterranean and Aegean coasts, and gives extensive information about navigation and nautical astronomy. The volume contains 209 capacity with 215 maps, charts and pictures to give verbal account of the coasts and islands of the Mediterranean and the Black Sea, along with a description of the seas. Basically the volume is a kind of guide to navigation and is based on his personal observations. He gathered together all previous data on the subject field simply added to it other applied cognition necessary for sailors on the most important littoral routes, and drew large maps for every chapter. In this way, the book became not only a elementary guide book, simply also the greatest Ottoman contemporary portolano with the most advanced cartography techniques.

3.2. Seydī Ali Reis

Another outstanding personality was the Ottoman admiral, geographer, astronomer and poet Seydī 'Ali Reis (also as known Kātibī or Kātib-i Rûmī) (d. 1562), who was an good on marine geography [22]. He wrote books on geography, mathematics and astronomy which testify his scientific and navigational experience and knowledge. His works, written in Turkish, are chiefly translations from Western farsi or Standard arabic and deal with mathematics, astronomy and navigation in the Indian Ocean. Some of his works accept been translated into many languages. In addition to geography, he likewise wrote books on mathematics and astronomy. He wrote a very valuable work in Turkish, entitled Kitāb al-Muhīt fī 'ilm al-aflāk wa al-Abhur well-known as al-Muhīt (The Ocean) containing the astronomical and geographical information required for long bounding main voyages as well as his own observations nearly the Indian Ocean. Afterward his travelogue, this is Saydī 'Ali's most famous work, and is based on Standard arabic works dealing with navigation in the Indian Ocean. The al-Muhīt consists of 10 sections and of Portuguese voyages of discovery, including Magellan's circumnavigation of the globe [23]. Saydī 'Ali's account enhances the reputation of the Ottoman sultan among his co-religionists everywhere he travelled, and demonstrates the universality of the Turkish element and the effectiveness of Ottoman Turkish soldiers, who were in demand at every courtroom.

In addition to this geographical piece of work, he also wrote treatises on astronomy. The outset of which is Mir'āt-i kāināt (Mirror of the Universe), a treatise on astronomical measurements and instruments, chiefly applicable to the art of navigation by celestial observation. This has been translated into many languages. His 2d book on astronomy is Hulāsat al-hay'a (Essence of Astronomy), a treatise on geometry and mathematics containing a translation of 'Ali Qushji'south al-Fathiyya fī al-Hay'a, enriched with excerpts from Chaghmīnī and Kadizade-i Rumī. His other books on astronomy are: Risala-i Dhāt al-Qursī a treatise about astronomy and some astronomical instruments; Risala-i mir'at-i kā'inat min alāt-i irtifa' which is called the Mirror of the Universe according to instruments for measuring altitude. His other works are: Risala-yi hay'at (Treatise on Astronomy); Sayahat-nāma-yi asturlab rub' mujayyab 'amal bi'l-jayb muqantarāt da'ira al-mu'addal dhāt al-kursī (Book of travel on the astrolabe, sine Quadrant, Equatorial Circumvolve, and the Instrument with a Throne); Risala-i Da'irat al-Mu'addil [24];Risala-i Asturlab and Risala-i Rub'i Mujayyab.

Another meaning Ottoman polymath scholar was Matrakci Nasûh b. Karagöz al-Bosnawī al-Silahī [25]. He was renowned in the xvi^thursday century every bit a mathematician, historian, geographer, cartographer, topographer, musketeer, and was an outstanding soldier, calligrapher and engineer. He made contributions in the fields of geography, mathematics, history, military art and calligraphy and produced important books. He also invented a military lawn game called "Matrak". Matrakçi Nasuh was an important figure in the field of descriptive geography. His first important book Bayān-i Manāzil-i Safar Iraqayn (Explanation of encamping places of 2 expeditions of Iraq) was in Turkish [26]. His miniatures showing the roads connecting Istanbul, Tabriz and Baghdad are like maps. His history of the 1534-36 campaign to Iran and Iraq [27] includes a double page depicting Istanbul with all the gimmicky structures of the city shown in remarkable item [28]. The Gilt Horn runs vertically in the eye, separating the Galata section with its famous tower (on the left) from the urban center proper (on the right), which includes such major structures as the Topkapi Palace, Hagia Sophia, At Meydani (Hippodrome), Grand Bazaar, One-time Palace, and the complex (kulliya) of Mehmed 2. A major document for the report of Istanbul in the 1530's, the illustration is an example of the topographic genre of painting initiated by Nasuh that continued for centuries.

Matrakçi's land maps are considered equal with Pīrī Reis' portland maritime maps to be constitute in his Kitāb-i Bahriye [29]. Two other works of Matrakçi containing miniatures are important from a geographical perspective. In one called Ta'rikh-i Fath-i Shiklos wa Estergon wa Istolnibelgrad, Matrakçi drew the inns between Istanbul and Budapest equally well as the cities of Nice, Toulon and Marseilles during Barbaros' visits and the Ottoman fleet with which he came [xxx].

As a fellow member of the administration, Nasuh accompanied Suleyman the Magnificent on various campaigns and carefully recorded the events and illustrated the cities and ports conquered by the Ottomans. He participated in the Mohaç campaign (1526) and the two Baghdad expeditions of Suleyman. He painted the picture of every city where the ground forces was billeted or passed past [31].

Another piece of work of the 16^thursday century in the field of geography, which contains data about the geographical discoveries and the New World (America), is the volume entitled Tārih-i Hind-i Garbī (History of the Due west Indies) (probably written by Muhammad b. Amir al-Suûdī al-Niksarī (d. 1591) in the 16^thursday century) [32]. This work, based on Castilian and Italian geographical sources, was presented to Sultan Murād 3 in 1573. It is important in showing that the Ottomans knew about the geographical discoveries of the West. The work has three parts; but the existent weight, consisting of two-thirds of the volume, is in the third department where Columbus' discovery of America and the European conquests over the period of sixty years between 1492 and 1552 are related. Tarih-i Hind-i Garbī tells the amazing stories of the explorations and conquests of Columbus, Cortes, Pizarro, and others, and it too endeavours to comprise the new geographic information into the body of Islamic cognition. It presents a major endeavor past an Ottoman Muslim scholar, almost unique in the 16^thursday century; firstly, to transmit through translation information from one culture (European Christendom) to another (Ottoman Islam), and secondly, to right and expand Islamic geography and cartography [33].

In the Topkapi Palace Museum Library (Hazine 644), Istanbul, there is an Atlas entitled "Ali Macar Reis Atlas". The atlas consists of six portolan charts and one mappamundi, all on double pages, i.eastward., there are fourteen pages [34]. They are drawn on parchment leaves and bound in leather, forming an appealing small book [35]. Equally a work of art, this atlas certainly ranks among the most successful. The artist-cartographer who drew these charts must have been professionally connected to those who drew other similar maps in Christian Europe; and the artistic perfection of this atlas strongly argues against information technology being the isolated work of a helm who would simply have been imitating such models; the author must have been a craftsman with nifty experience of this type of work.

Cartography seems to take been organized as a profession in the Ottoman Empire; for example, in the 17^th century, fifteen individuals were occupied with the art of surveying, in eight locations in Istanbul and nearby areas.

Ottoman geographers were able to obtain data about both West and East at a time when in that location were no maps of the East bachelor in Europe. This indicates that the Ottomans were more advanced in this area than had previously been thought.

Ottoman contributions to geography including cartography are very meaning, vast, in content and accept a definite place in the history of geography. Information technology is too true that while the Arabs mostly influenced the Turks they did not follow them slavishly. Ottoman geographers especially cartographers fabricated some very pregnant contributions and they may be said to have formed a bridge between medieval Islamic and modern cartography [36].

4. Decision

Ottoman contributions to Science and Engineering during a six hundred year rule over a huge domain are beyond measure. The in a higher place is only a cursory outline of some of the Ottoman scientific activities and related institutions that brought about the revival of culture, science, and learning in civilizations throughout the world. Many excellent works exist that can guide future researchers interested in this subject. Opportunities for further report grow, as the examples presented in this paper could certainly be extended to cover a larger per centum of the vast contributions the Ottomans made over six hundred years. The classical scientific tradition that produced its finest works in the about magnificent period of the Empire was set up forth in the scientific and educational institutions that have been briefly mentioned, in the scholarly circles established, and developed around these institutions. Still, the Ottoman classical tradition was preserved during this second phase of Ottoman scientific discipline, when many more translations and transfers were fabricated from European languages, and survived with some of its bones elements until the second one-half of the xix^th century.

[34] On the folio 4b in that location is i notation about the author. It is a short judgement in Standard arabic forth the right hard margin of the folio, in the area of the Atlantic along the western declension of Spain; the judge translation: 'The Apprehensive Ali Macar wrote it with the assistance of the Lord of Conclusion (i.e., God) in the month of Safar, year 975′, i.e., between August vii and September 4, 1567. No other nautical chart or atlas made past him is known. The commencement impression thus might be that an Ottoman seaman made this atlas on the basis of his maritime experience. And despite the date given of 1567, in that location is minor yet significant evidence that he drew this atlas before 1542; for on 6a, Scotland is separated from England by a channel which disappeared from Italian charts after that year.
