Well preserved, it still bears the reliefs of the 8 winds and the carvings of a sundial under each of them. The original rods of the sundials are not extant, only the holes. Varro [1st c. BCE] calls it a clock [horologium, in ReRus 3.5.17], and we learn from Vitruvius of the 1st c. BCE [deArch. 1.6.4], about a bronze Triton on top serving as wind-vane. There’re also traces of a water-clock, like a turret on the south side, which was probably a water-tank/cistern.
