However, few people know that it also houses valuable scientific instruments, such as the great gnomon designed by the mathematician Paolo Dal PozzoToscanelli. Constructed in the fifteenth century and installed at a height of 90 metres at the summit of Brunelleschi's cupola, it is the one of the tallest gnomons known to exist. It projects the image of the Sun onto the pavement beneath at the time of transit through the local meridian on the days around the summer solstice. This book tells the story of this extraordinary astronomical instrument which was used for scientific purposes for over three hundred years, offering fascinating insights into both the history of astronomy and that of the Cathedral itself.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Stefano Barbolini,Giovanni Garofalo\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 8859616360\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9788859616368\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Edizioni Polistampa\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/03\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 112\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback","brand":"Stefano Barbolini","offers":[{"title":"Paperback","offer_id":48450158035199,"sku":"9788859616368","price":19.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_7a23150a-86f7-4a25-9fd7-ae6631936b5d.jpg?v=1777266458","url":"https:\/\/www.whiterainbookhouse.com\/products\/lo-gnomone-di-santa-maria-stefano-barbolini-9788859616368","provider":"WR Book House","version":"1.0","type":"link"}
