With the application of trigonometry on a higher level and more accurate than ever before, Muslim astronomers developed new devices and techniques. One of these first-of-its-kind devices is the astrolabe quadrant, which is a simpler and easier-to-use version of the astrolabe. This instrument, albeit less accurate than the large-scale ones, is quite practical since it has all the markings of an astrolabe's front and rete, only inside a quarter of a circle. This small and portable device can be used by anyone who has a basic knowledge of astronomy and a simple user manual. It became popular specifically among those astronomers who worked on timekeeping. Although it is a very popular instrument, manuals for making it are quite rare. Muhammad ibn Kātib Sīnān al-Qunawī al-Muwaqqit (d. c. 1524), one of the most important Otto-man astronomers in this regard, wrote two treatises on how to make an astrolabe quadrant: Hadiyyat al-Mulūk and Risala fī ma'rifat wad' al-rub' al-dāirat al-mawdu' 'ala al-muqantarāt. Both of these treatises are the earliest manuals in Turkish for making this instrument. This article aims to introduce manuals for instrument-making via the example of Qunawī's detailed explanatory remarks in his Hadiyyat al-Mulūk. It follows his instructions step by step and uses his tables. At the end of the article is an astrolabe quadrant drawn according to his instructions. For more comprehensive studies, the transliteration of the treatise is attached in the appendix.

Since the Ottomans had no intention of reinventing the wheel, they began accumulating this already advanced knowledge via copying manuscripts, providing safe haven for scholars fleeing political instability in the East, establishing madrasas, and other methods. Most of the mathematical sciences such as algebra, arithmetic, and ʿilm al-hayʾa, were transmitted from the successive schools of Maragha, Tabriz, and Samarqand. The science of timekeeping, however, had a unique source: the Mamluks. During the thirteenth fifteenth centuries, Mamluk astronomers worked exclusively on timekeeping and produced arguably the best treatises in this discipline. It was, therefore, no surprise that the Ottoman reception of timekeeping was based on these works. This paper will discuss the exact starting point of this transmission and introduce ʿUmar al-Dimashqī, a Mamluk astronomer from Damascus who lived in Istanbul and Edirne, as the responsible party. The texts in his timekeeping compendium, the Hamidiye 1453, will be examined in detail and its role as a bridge between Mamluk, Samarqand, and Istanbul knowledge traditions will be discussed.

Osmanlıların tekerleği yeniden icat etmek gibi bir kaygıları olmadığından, bu tekemmül etmiş bilgi birikimini çeşitli yollarla edinmeyi tercih ettikleri görülür. Yazma eserleri kopyalama, doğudaki siyasi karmaşadan kaçan ulemaya güvenilir yaşam imkânları sunma, medreseler inşa etme bu yollardan bazılarıdır. Cebir, aritmetik, heyet ilmi gibi matematiksel bilimlerin çoğu birbirini takip eden Merâga, Tebriz ve Semerkant okullarından aktarılmıştır. Fakat mîkât ilmi, özgün bir kaynağa sahiptir. On üçüncü ve on beşinci yüzyıllar arasında Memlük astronomları özel olarak mîkât ilmiyle uğraşmış ve bu alanda bilinen en kapsamlı ve yetkin eserleri meydana getirmişlerdir. Doğal olarak Osmanlıların mîkât ilmini benimseyişi de onların çalışmaları üzerinden olur. Bu makale, bu benimseyiş sürecinin tam olarak ne zaman başladığını tartışır ve on beşinci asırda Edirne ve İstanbul’da yaşamış Şam kökenli bir Memlük astronomu olan Ömer ed-Dımaşkî’yi bu sürecin tetikleyicisi olarak tanıtır. Onun hazırladığı mîkât ilmi mecmuası, Hamidiye 1453, ayrıntılı biçimde incelenir ve eserde bulunan deliller üzerinden bu mecmuanın Memlük-Semerkant-İstanbul üçgeninde nasıl bir köprü vazifesi gördüğü ele alınır.

The 15th century emergence of the Ottoman scientific endeavours occurred at a fortunate time when scientific knowledge in the Islamic world was already advanced. Since the Ottomans never had an intention to reinvent the wheel, instead, they began accumulating this already advanced knowledge via several methods of transmission. Copying the manuscripts, providing safe haven for scholars who run from the political instability in the East, establishing madrasas are some among these methods. Most of the transmission of mathematical sciences such as algebra, arithmetic, ʿilm al-hayʾa etc. were from successive schools of Maragha, Tabriz, and Samarkand. The science of timekeeping, however, had a unique source: the Mamluks. The 13th-15th centuries Mamluk astronomers worked exclusively on timekeeping and produced arguably the most sufficient treatises in the area. Without a surprise, the Ottoman reception of timekeeping was based on their works. This paper will discuss the exact starting point of this transmission and introduce ʿUmar al-Dimashqī, a Mamluk astronomer from Damascus who lived in Edirne and Istanbul, as the responsible party. The texts in his timekeeping corpus, Hamidiye 1453, will be investigated in detail and this corpus will be examined for the role it played as a bridge between Mamluk, Samarqand, and Istanbul.
Keywords: ʿUmar al-Dimashqī, Mamluk astronomy, Ottoman astronomy, timekeeping, astronomical instruments, Hamidiye 1453.

A timekeeper would be responsible for finding important dates and times for the religious practices such as the beginning of the fasting month Ramadan and the five daily prayers. Although the concept of timekeeper did emerge in Baghdad in the 9th century, the official post was created for the first time by Mamluks who ruled Egypt, Palestine, and Syria between the mid-13th and early 16th centuries. This practice was later adapted by Ottomans in the late 15th century only to be continued until 1952 in modern Turkey. House of timekeeper, dār al-muwaqqit in Arabic and muwaqqitkhāna in Ottoman Turkish, would usually be built in the mosque annexes. Standard instruments (i.e. astrolabes, quadrants…) for observation and calculation and a library, which ideally would contain numerous treatises on mathematical sciences, would be stored in these buildings. The textual evidences suggest that the Mamluk astronomers were not satisfied with using only standard instruments and worked on perfecting and simplifying instruments for accuracy and user friendliness. The works of two astronomers explicitly attest to this claim: ʿAlāʾ al-Dīn ʿAlī ibn Ibrāhīm (d. circa 1375), known as Ibn al-Shāṭir, and Shihāb al-Dīn Aḥmad ibn Abī Bakr (fl. 14th century), known as Ibn al-Sarrāj, were actively involved with instrument making as they designed and invented several sophisticated artefacts for observation and calculation. Type of projections, reference points for sets of markings and methods of their use were almost unique in the instruments such as hidden sine graph (jayb al-ghāʿib) or complete quadrant (rubʿ al-tāmm). Unfortunately, aiming for the stars did not make their instruments popular. This paper will briefly introduce the standard instruments at the house of timekeeper and discuss why the sophisticated ones never turned into standard assets.

He was famous for his voluminous work Jāmiʿ al-mabādī wa alghāyāt fī ʿilm al-mīqāt (An Encyclopaedia of Timekeeping: From A to Z) which deals with the construction and use of dozens of instruments ranging from universal plates to sundials. Although many of the instruments were already known before Marrākushī, some are of his own design. He introduced a celestial globe with a quadrant and two rings. The quadrant was a unique addition to the traditional globe; its main purpose was to achieve high accuracy in calculations. Unfortunately, no globes of this type are extant; indeed, there is no mention of a celestial globe with a quadrant in any of the relevant sources. This seems contradictory since Marrākushī was extremely influential in instrumentation and his work was widely used around the Islamic world. This paper argues for the utility of Marrākushī's model and questions the lack of its influence on globe-making traditions in the Islamic world from the thirteenth to the nineteenth centuries.

He continued the timekeeping tradition established by the Mamluk astronomers in between 13 th-15 th centuries. He started the Turcifica tio n movement on timekeeping by translating into and compiling in Turkish for the first time. His works influenced Ottoman astronomers greatly over centuries. His main goal was to improve the practicality on timekeeping and his most extensive work, Mīzān al-Kawākib, is a great example of this. Mīzān al-Kawākib consists of tables for timekeeping not by the Sun as usual but by the stars and contains more than 240000 numerical values. It is the only extensive work of its kind in the timekeeping literature. As he revealed in the introduction Muḥammad ibn Katib Sīnān compiled these tables with the intention of eliminating the necessity of using instruments to determine the time at night. The book comprises of an introductory about how to use the main tables, a star catalogue for some 500 stars and the tables for timekeeping for four functions. Since these kind of tables require knowledge for calculations from zījes and furthermore using them is impractical during the daytime, his approach on this work, albeit is a progressive one, did not make a lasting impact on Ottoman timekeeping while preparing the traditional tables for timekeeping by the Sun prevailed over centuries. The aim of this presentation is to express Muḥammad ibn Katib Sīnān's progressive idea and discuss the efficiency of his method of observation.
