{"product_id":"astrolabe-plate-with-rojas-projection-e5581-2","title":"Astrolabe: plate with rojas projection","description":"This is a rare example of an astrolabe that has been printed on paper, cut out, and mounted on a board. Other surviving examples are mostly French or German and are from the 16th century. This instrument is a 'complete' astrolabe, incorporating all the different types of astrolabes. As such, it forms an interesting teaching device that can demonstrate the history and development of the astrolabe. The fact that it was brightly coloured would certainly have enhanced its instructive nature. Bion wrote one of the most important books on scientific instruments: 'TraitÔòáde la Construction et Principaux Usages des Instruments de MathÔòá┬«matique' (Paris, 1709), (The construction and principal uses of mathematical instruments), in which he described this style of astrolabe. The book was translated into English in 1723 and the Museum recently acquired one of these editions. \u003cbr\u003eNicolas Bion","brand":"prodigi","offers":[{"title":"Fine art poster \/ XS: 30 x 30cm \/ none","offer_id":57007344746878,"sku":"GLOBAL-FAP-12X12","price":22.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ S: 40 x 40cm \/ none","offer_id":57007344779646,"sku":"GLOBAL-FAP-16X16","price":28.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ M: 50 x 50cm \/ none","offer_id":57007344812414,"sku":"GLOBAL-FAP-20X20","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ L: 70 x 70cm \/ none","offer_id":57007344845182,"sku":"GLOBAL-FAP-28X28","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XL: 80 x 80cm \/ none","offer_id":57007344877950,"sku":"GLOBAL-FAP-32X32","price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XXL: 100 x 100cm \/ none","offer_id":57007344910718,"sku":"GLOBAL-FAP-40X40","price":82.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XS: 30 x 30cm \/ none","offer_id":57007344943486,"sku":"MUS-CFPM-12X12","price":59.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ S: 40 x 40cm \/ none","offer_id":57007344976254,"sku":"MUS-CFPM-16X16","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ M: 50 x 50cm \/ none","offer_id":57007345009022,"sku":"MUS-CFPM-20X20","price":119.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ L: 70 x 70cm \/ none","offer_id":57007345041790,"sku":"MUS-CFPM-28X28","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XL: 90 x 90cm \/ none","offer_id":57007345074558,"sku":"MUS-CFPM-36X36","price":204.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ Single","offer_id":57007345107326,"sku":"GLOBAL-POST-MOH-6X4","price":1.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 10-pack","offer_id":57007345140094,"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":57007345172862,"sku":"GLOBAL-POST-MOH-6X4-20","price":24.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ Single","offer_id":57007345205630,"sku":"GLOBAL-POST-MOH-7X5","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 10-pack","offer_id":57007345238398,"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":57007345271166,"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":57007345303934,"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":57007345336702,"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":57007345369470,"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":57007345402238,"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":57007345435006,"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":57007345467774,"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\/products\/e5581-2_9fa7b027-8a19-40ce-b166-bbc38208b21b.jpg?v=1527598066","url":"https:\/\/prints.rmg.co.uk\/products\/astrolabe-plate-with-rojas-projection-e5581-2","provider":"Royal Museums Greenwich prints","version":"1.0","type":"link"}
