A quadrant is a navigational or an astronomical instrument featuring a graduated arc measuring angles up to 90\u00b0. This one has engraved numbers in increments of ten from 0 to 90 and marking every five degrees. A fixed iron strut at the 45 degree mark is engraved with a design of flowers and leaves. At the top of the arc is a figurine of a brass unicorn; at the bottom of the arc is a tiny brass cherub holding a fish. A rotating brass pointer is attached to the opposite bottom corner with a brass key that allows it to pivot and point to the numbers on the arc. At the top of the pointer is a decorative brass finial with a pinhole opening and facing it at the bottom, a similarly pierced brass tube, presumably for sighting or alignment as part of its use as a measurement device. The bottom of the quadrant is attached to a metal sphere which sits inside a floral setting so it can be rotated on the stand. Tightening a brass key holds it in place. The quadrant is stamped &#8220;Made in Italy,&#8221; and was likely produced for export or for sale to foreign visitors.<\/p>\n<p>Product description continues below.<\/p>\n","protected":false},"featured_media":19255,"template":"","meta":{"wds_primary_product_brand":0,"wds_primary_product_cat":0,"footnotes":""},"product_brand":[],"product_cat":[5975,4227,6840,4191,5349,6813,6797,944],"product_tag":[7169,808,1023,2266,203,7359,120,1145,6853,7355,7107,7790],"class_list":{"0":"post-19251","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-astronomy-outer-space-exploration","7":"product_cat-corporate-gifts-decor","8":"product_cat-fathers-day","9":"product_cat-gentlemans-man-cave","10":"product_cat-graduation-gifts","11":"product_cat-maritime-history","12":"product_cat-prop-rentals","13":"product_cat-scientific-instruments","14":"product_tag-antiques","15":"product_tag-astronomical","16":"product_tag-brass","17":"product_tag-iron","18":"product_tag-italian","19":"product_tag-maritime-antiques","20":"product_tag-navigation","21":"product_tag-octant","22":"product_tag-prop-rental","23":"product_tag-quadrant","24":"product_tag-scientific-instrument","25":"product_tag-sextant","26":"post","27":"post-with-thumbnail","28":"post-with-thumbnail-large","30":"first","31":"instock","32":"shipping-taxable","33":"purchasable","34":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product\/19251","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":1,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product\/19251\/revisions"}],"predecessor-version":[{"id":19260,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product\/19251\/revisions\/19260"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/media\/19255"}],"wp:attachment":[{"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/media?parent=19251"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product_brand?post=19251"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product_cat?post=19251"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.georgeglazer.com\/wpmain\/wp-json\/wp\/v2\/product_tag?post=19251"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
