The central ring consisted of two semicircles, bearing 2 pairs of engravings of 7 grooves defining the months (zodiacs) for 4 different latitudes-towns). The inner ring bore a hole on its periphery, while around it there were engravings dividing it into 12 equal parts which defined the 12 hours. During the clock operation, the semicircle with the data of the area was turned by 90º and the inner ring was placed on the current month; thus a bright spot indicated the hour on the opposite side. The clock could also be used at midday of the equinoxes in order to find the latitude of a place, the azimuth and the star height.

It consisted of graduated in degrees quadrant which had an aiming device at one edge and from its centre hung a plumb bob. The latitude of each place could be found directly by aiming the Pole Star (it was equivalent to the complement angle of the angle that was shaped by the aiming line with the thread) and indirectly by the measurement of the zenith of some other celestial body (e.g. the Sun). Later on straight lined scales were engraved on the surface of the instrument for the conversion of the terrestrial angles in the proportions of lengths but also monthly arcs with curved hour lines for one or more latitudes. A moving button was also added which slid at length of the thread and was regulated depending on the month which was indicated by the zodiac at the other edge of the instrument. The instrument could be used as a position locator at any given hour of the day, while with any given latitude as a sundial. The level astrolabes constitute its evolution.\u003c\/p\u003e","brand":"kotsanasmuseumshop","offers":[{"title":"Default Title","offer_id":53638487441699,"sku":"","price":50.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0918\/6063\/1843\/files\/DSC8792.jpg?v=1747071683"}],"url":"https:\/\/kotsanasmuseumshop.com\/en-gr\/collections\/highlights-from-ancient-innovation.oembed","provider":"kotsanasmuseumshop","version":"1.0","type":"link"}
