Sundial with the heads of Athena, Helios and Dionysus

The reconstructed indicator (gnomon) of the conical sundial is located in the projection of the vertical middle hour line (midday line). The time was read by the endpoint of the shadow cast by this indicator. Sundials were set up both in the public and in the private sphere. This piece in particular is also decorated with portraits of the gods Athena, Helios and Dionysus.
