Sundial in Follonica (Grosseto)
Latitude 42° 55' 24" N - Longitude 10° 45' 03" E
This analemmatic horizontal sundial spreads over a circle with a diameter of 6 meters in a wonderful position on the promenade of Viale Italia at Follonica. A large Sun characterizes this sundial; the seventeen hour points, from four to twenty, are arranged on an imaginary elliptical line and are drawn by the long Sun rays; in the central part, the scale of the dates placed on the meridian South/North line indicates the first day of each month. The time is read from the dial by noting where the shadow cast by a person placed with the feet together on the scale of dates and preferably rigidly raising a hand, crosses hour points. A fine mixture of colours characterizes this large sundial made of a base in polished marble chips (Venetian technique) in which the various elements made with coloured marbles are embedded with the Palladian technique. Analemmatic sundials are perfect as large mathematical sculptures.
