{"product_id":"astrolabe-dismounted-reverse-e5556-3","title":"Astrolabe: dismounted reverse","description":"\u003cp\u003eThis small astrolabe is the only complete, preserved example from this maker. There is also a solitary mater by him in the Institute du Monde Arabe, Paris (IC no. 3534) and another mater with accompanying plates in the Rahni KoÔòá├▒ Museum, Istanbul (IC no. 4101).The throne consists of pierced motifs delineated by silver inlay, identical on the front and back. The stem is rather tall and the suspension ring relatively small: both may not be original. The mater is devoid of markings and its surface is damaged in the lower right quadrant. The rete is cut for 23 dagger- and sickle-shaped star pointers, two of which together look like a pair of facing tiger's claws symmetrical to the vertical diameter. There are three plates covering latitudes 30├òÔòØ\/40├òÔòØ, 33├òÔòØ\/36├òÔòØ and 38├òÔòØ. On the back of the instrument, the signature of the maker is engraved along the rim of the lower-left quadrant: 'Made by Mahmud ibn Shawka al-Baghdadi in the year AH 694' (AH 694 approximates to 1294-95 AD). The alidade is a rather crude replacement, although old, but the peg, wedge and ring are probably original.Mahmud ibn Shawka al-Baghdadi\u003c\/p\u003e","brand":"prodigi","offers":[{"title":"Fine art poster \/ XS: 30 x 30cm \/ none","offer_id":57166271283582,"sku":"GLOBAL-FAP-12X12","price":22.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ S: 40 x 40cm \/ none","offer_id":57166271316350,"sku":"GLOBAL-FAP-16X16","price":28.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ M: 50 x 50cm \/ none","offer_id":57166271349118,"sku":"GLOBAL-FAP-20X20","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ L: 70 x 70cm \/ none","offer_id":57166271381886,"sku":"GLOBAL-FAP-28X28","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XL: 80 x 80cm \/ none","offer_id":57166271414654,"sku":"GLOBAL-FAP-32X32","price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XXL: 100 x 100cm \/ none","offer_id":57166271447422,"sku":"GLOBAL-FAP-40X40","price":82.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XS: 30 x 30cm \/ none","offer_id":57166271480190,"sku":"MUS-CFPM-12X12","price":59.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ S: 40 x 40cm \/ none","offer_id":57166271512958,"sku":"MUS-CFPM-16X16","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ M: 50 x 50cm \/ none","offer_id":57166271545726,"sku":"MUS-CFPM-20X20","price":119.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ L: 70 x 70cm \/ none","offer_id":57166271578494,"sku":"MUS-CFPM-28X28","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XL: 90 x 90cm \/ none","offer_id":57166271611262,"sku":"MUS-CFPM-36X36","price":204.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ Single","offer_id":57166271644030,"sku":"GLOBAL-POST-MOH-6X4","price":1.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 10-pack","offer_id":57166271676798,"sku":"GLOBAL-POST-MOH-6X4-10","price":14.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 20-pack","offer_id":57166271709566,"sku":"GLOBAL-POST-MOH-6X4-20","price":24.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ Single","offer_id":57166271742334,"sku":"GLOBAL-POST-MOH-7X5","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 10-pack","offer_id":57166271775102,"sku":"GLOBAL-POST-MOH-7X5-10","price":19.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 20-pack","offer_id":57166271807870,"sku":"GLOBAL-POST-MOH-7X5-20","price":29.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ Single","offer_id":57166271840638,"sku":"GLOBAL-GRE-MOH-6X4-BLA","price":2.5,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ 10-pack","offer_id":57166271873406,"sku":"GLOBAL-GRE-MOH-6X4-BLA-10","price":15.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Standard: 6 x 4in \/ 20-pack","offer_id":57166271906174,"sku":"GLOBAL-GRE-MOH-6X4-BLA-20","price":26.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ Single","offer_id":57166271938942,"sku":"GLOBAL-GRE-MOH-7X5-BLA","price":3.5,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ 10-pack","offer_id":57166271971710,"sku":"GLOBAL-GRE-MOH-7X5-BLA-10","price":19.95,"currency_code":"GBP","in_stock":true},{"title":"Greetings card \/ Large: 7 x 5in \/ 20-pack","offer_id":57166272004478,"sku":"GLOBAL-GRE-MOH-7X5-BLA-20","price":33.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2785\/2654\/files\/e5556-3.jpg?v=1774463355","url":"https:\/\/prints.rmg.co.uk\/products\/astrolabe-dismounted-reverse-e5556-3","provider":"Royal Museums Greenwich prints","version":"1.0","type":"link"}
