Windsor Ontario Canada Vertical Dial 874
A vertical stone sundial made of white quartzite approximately in a 6 x 4 feet rectangle. The dial face includes engraved hour lines from 7am to 6pm in Arabic hour numerals for Eastern Daylight Time and an elegant engraved outline of St. Dimitrije based on a partially preserved 14th century fresco of the Saint in St.Mary's Church, Donja Kamenica, Serbia. Rather than summer and winter solstice lines, a single hyperbola indicates the route of the gnomon shadow's tip on 8 November - the day of St.Demetrius (St. Dimitrije). In fact, the gnomon is represented at St. Demetrius' sword (or more appropriately, his spear). A small bell is engraved at 10am indicating the time of morning liturgy. At about 11:15 if you look closely, you can see the subnode point (polos montaza) of the gnomon tip used for alignment during construction.
