Aimant Clock in the Duomo by Paolo Uccello

Clock in the Duomo (1443), Florence, Italy by Paolo Uccello (1397-1475) is a vintage Renaissance fine art fresco painting. A clock face with Roman numerals which is painted in an Italian cathedral church in Florence, Italy. It's a huge 24-hour clock with a single hand and was painted with four frescoes of Prophets in the corners. It is a liturgical clock, which calculates the 24 hours from Sunset the previous day. This is one of the few clocks still in existence and in working order from that time, and one of the very few liturgical clocks.
