{"product_id":"astrolabe-dismounted-reverse-e5541-2","title":"Astrolabe: dismounted reverse","description":"The mater and three of the five plates are late Ottoman and datable to circa 1800 whereas the rete is of a much higher quality and is Iranian, possibly dating from the late-18th or early-19th century. The other two plates are probably by the same maker as the rete, since they are also Iranian and of a better quality than the rest of the instrument. It could be that the maker of the mater had acquired the rete and two plates and then decided to construct a complete astrolabe using them.\u003cbr\u003e\u003cbr\u003eThe throne is plain, with lateral lobes and a square base. The mater has 'spiralling' lines and concentric circles, presumably for a gazetteer which has not been engraved. The plates cover latitudes between 30├òÔòØ-40├òÔòØ. The back of the instrument bears a zodiacal\/calendrical scale with Seleucid month-names, from which the Ottoman identification is gained. The alidade is a non-functional replacement, the mater being twice as large as it is, and the wedge is also a replacement, dated 1970.","brand":"prodigi","offers":[{"title":"Fine art poster \/ XS: 25 x 20cm \/ none","offer_id":57022694424958,"sku":"GLOBAL-FAP-8X10","price":22.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ S: 30 x 25cm \/ none","offer_id":57022694457726,"sku":"GLOBAL-FAP-10X12","price":28.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ M: 50 x 40cm \/ none","offer_id":1863135035436,"sku":"GLOBAL-FAP-16X20","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ L: 75 x 60cm \/ none","offer_id":57022694490494,"sku":"GLOBAL-FAP-24X30","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XL: 100 x 80cm \/ none","offer_id":57022694523262,"sku":"GLOBAL-FAP-32X40","price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XXL: 127 x 100cm \/ none","offer_id":57022694556030,"sku":"GLOBAL-FAP-40X50","price":82.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ S: 36 x 28cm \/ none","offer_id":57022694588798,"sku":"MUS-CFPM-11X14","price":59.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ M: 50 x 40cm \/ none","offer_id":1863135264812,"sku":"MUS-CFPM-16X20","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ L: 80 x 60cm \/ none","offer_id":57022694621566,"sku":"MUS-CFPM-24X32","price":119.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XL: 100 x 75cm \/ none","offer_id":57022694654334,"sku":"MUS-CFPM-30X40","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ Single","offer_id":57022694687102,"sku":"GLOBAL-POST-MOH-6X4","price":1.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 10-pack","offer_id":57022694719870,"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":57022694752638,"sku":"GLOBAL-POST-MOH-6X4-20","price":24.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ Single","offer_id":57022694785406,"sku":"GLOBAL-POST-MOH-7X5","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 10-pack","offer_id":57022694818174,"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":57022694850942,"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":57022694883710,"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":57022694916478,"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":57022694949246,"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":57022694982014,"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":57022695014782,"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":57022695047550,"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\/e5541-2.jpg?v=1772677265","url":"https:\/\/prints.rmg.co.uk\/products\/astrolabe-dismounted-reverse-e5541-2","provider":"Royal Museums Greenwich prints","version":"1.0","type":"link"}
