![]() Nocturnal And Sundial The back of the instrument bears a quadrant, divided into 90?, and the hour lines for a sundial. The nocturnal allows the time to be calculated during the night by using the polar star as a reference point. This dial, dated, signed and calibrated for a latitude of 43? 44', corresponding to Florence, is very similar to another, which originates from the Medici collections. |
