Paolo Uccello’s Clock in the Florence Cathedral
The clock of the Duomo in Florence is one of the oldest functional mechanical clocks. The dial is a fresco painted by one of the greatest artists of the Renaissance, Paolo Uccello. The clock is one of only a few examples in the world that marks the Italic hour, measuring time from sunset to sunset. Thus, “Paolo Uccello’s clock” is both a timepiece and a work of art.
