Syncretic Tellus reclining with four children, probably the Seasons, accompanied by Aion-Uranus within a zodiac wheel (mosaic from Sentinum, AD 200-250, Glyptothek)
Tellus has other four children, that we can see represented in the mosaic. Generally they represented the four season, since Tellus was also worshipped as crops deity. In fact the children wear seasonal ornaments, such as fruits, ears of corn, ice crystals and hunting weapons. They seem to support the hypothesis of the flowing of the yearly time.
