{"product_id":"string-gnomon-dial-f2474","title":"String-gnomon dial","description":"\u003cp\u003eThis dial comprises an octagonal-shaped dial plate on which is an hour scale set around a compass. The cardinal points on the compass are marked by Latin initials and an arrow is drawn west of North to indicate magnetic variation. A glass plate covers all. Hinged to the dial-plate is a shaped gnomon support which folds flat when not in use. It is pierced at its lower end for a plumb line and bob (both missing). Fixed to the top end of the support is a green string gnomon which is attached to the dial plate by means of a strut set across the compass glass. The dial is supported by three levelling screws. It has an eight-sided fishskin covered case with a red seal impression on its outside. The dial was reputedly given by Admiral Nelson to Captain (later Vice-Admiral) Sir Thomas Boulden Thompson (circa 1766-1828) on the morning of the Battle of the Nile (1798).\u003c\/p\u003e","brand":"prodigi","offers":[{"title":"Fine art poster \/ XS: 30 x 30cm \/ none","offer_id":57010807079294,"sku":"GLOBAL-FAP-12X12","price":22.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ S: 40 x 40cm \/ none","offer_id":57010807112062,"sku":"GLOBAL-FAP-16X16","price":28.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ M: 50 x 50cm \/ none","offer_id":57010807144830,"sku":"GLOBAL-FAP-20X20","price":38.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ L: 70 x 70cm \/ none","offer_id":57010807177598,"sku":"GLOBAL-FAP-28X28","price":54.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XL: 80 x 80cm \/ none","offer_id":57010807210366,"sku":"GLOBAL-FAP-32X32","price":69.95,"currency_code":"GBP","in_stock":true},{"title":"Fine art poster \/ XXL: 100 x 100cm \/ none","offer_id":57010807243134,"sku":"GLOBAL-FAP-40X40","price":82.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XS: 30 x 30cm \/ none","offer_id":57010807275902,"sku":"MUS-CFPM-12X12","price":59.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ S: 40 x 40cm \/ none","offer_id":57010807308670,"sku":"MUS-CFPM-16X16","price":79.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ M: 50 x 50cm \/ none","offer_id":57010807341438,"sku":"MUS-CFPM-20X20","price":119.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ L: 70 x 70cm \/ none","offer_id":57010807374206,"sku":"MUS-CFPM-28X28","price":159.95,"currency_code":"GBP","in_stock":true},{"title":"Framed picture \/ XL: 90 x 90cm \/ none","offer_id":57010807406974,"sku":"MUS-CFPM-36X36","price":204.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ Single","offer_id":57010807439742,"sku":"GLOBAL-POST-MOH-6X4","price":1.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Standard: 6 x 4in \/ 10-pack","offer_id":57010807472510,"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":57010807505278,"sku":"GLOBAL-POST-MOH-6X4-20","price":24.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ Single","offer_id":57010807538046,"sku":"GLOBAL-POST-MOH-7X5","price":2.95,"currency_code":"GBP","in_stock":true},{"title":"Postcard \/ Large: 7 x 5in \/ 10-pack","offer_id":57010807570814,"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":57010807603582,"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":57010807636350,"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":57010807669118,"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":57010807701886,"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":57010807734654,"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":57010807767422,"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":57010807800190,"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\/f2474_c3a5b275-5c8b-4bf4-9132-d59ba817ae60.jpg?v=1527709061","url":"https:\/\/prints.rmg.co.uk\/products\/string-gnomon-dial-f2474","provider":"Royal Museums Greenwich prints","version":"1.0","type":"link"}
