Islamic Antique Ottoman Astrolabe For Sultan Beyezid-ii :
ISLAMIC ANTIQUE OTTOMAN ASTROLABE FOR SULTAN BEYEZID-II size about4 inches This is an original functioning astrolabe - only made recently in the same technique and style by one of the descendants from the family of the original maker using the same treaties and identical notaions and inscriptions. ( Please read the full description to the very end ) A brass astrolabe made by al-Ahmar al-rumi for the treasury of the Ottoman Sultan Bayezid 2 Turkey,dated A.H.911/1505-06 A.D. comprising a mater with a double loop for suspension, three discs and an alidade, with incised details, the reverse with two calligraphic roundels, the pin modern 9.5cm.,3¾in. diameter;6mm,3/16in.thickness. This important astrolabe is one of two known pieces dedicated to the Ottoman Sultan Bayezid 2 (reigned 1481-1512 A.D.).T are no other known astrolabes dedicated to an Ottoman Sultan, not even in the Topkapi Sarayi Museum. This piece represents the beginning of a new Ottoman tradition in modestly- decorated astrolabs, a tendency to be observed already in various earlier Syrian pieces made by professional astronomers themselves rather than by professional craftsmen. The other, made in the previous year by Shukrallah Mukhlis Shirwani, is more than in the Persian tradition and is more ornately decorated in a distinctive style; it is preserved in the Museum of Islamic Art in Cairo. The makers of both works are not otherwise known (see further below). The history of early Ottoman astronomy in general (from the 14th to the early 16th century) has not yet been properly researched. It was influenced by the Seljuq Turkish tradition (Anatolia,13th century), of which very few sources and not a single instrument survive ;by the colorful Mamluk tradition (Egypt and Syria,13th -15th centuries)2,and by the vigourous likhanid and Timurid traditions(Iran and Central Asia,13th âe" 15th centuries)3.The sources for Ottoman astronomy have recently been properly documented for the first time4,and the amount of possible research for the future a daunting. The interest of Bayezid II for astronomy is well known.The institution of court munajjims (astronomer-astrologers)and mosque muwaqqits (timekeepers) were well established in his time. The Sultan studied mathematics and astronomy with his private teacher, who was none other than Miram Chelebi, the grandson of Qadi Zade al-Rumi,director of Ulugh Begâe(tm)s observatory at Samarqand, Numerous astronomers dedicated their works to Bayezis,including treatises on instruments and highly sophisticated tables. He himself commissioned his teacher to prepare a Persian Commentary to the astronomical tables of Ulugh Beg. The early Ottoman tradition of instrument making (14th -16th centuries) is represented only by these two presentation pieces for Bayezid 2. All other surviving Ottoman astrolabes are later than these two, indeed at least a century later. Out of a total of some 30 odd- pieces 6, none shows any indication of having been influenced specifically by either of these two pieces. The astrolabe of Bayezid - II The workmanship is competent but, primarily, this is an astrolabe designed to be used. The engraving , in kufic, is elegant and distinctive. The Arabic Alphanumerical(abjad) notation is used throughout, except for the date, which is written in Hindu-Arabic numerals. The throne is undecorated, with lobes on either side of the upper lobe and smaller protrusions at the far left and right. The suspension apparatus, a shackle and ring, is attached at the top of the throne. The mater bears a circumferential scale divided for each 5° and subdivided for each 1 °, labelled 5°-1°-5°-2°-âe¦-5-(3)6°.The base circles for the equinoxes and solstices are engraved in the inside of the mater.
