Tleson (active around 555-535 BC) was an Attic potter and perhaps also a vase painter in the black-figure style. He was the son of the famous potter Nearchos and brother of Ergoteles. His workshop apparently produced mostly Little-master cups. Most of his vases were painted by the Tleson Painter, whose real name is unknown, and whose conventional name is derived from Tleson. Based on the fact that vases known by that hand so far are only ever signed by Tleson, John Beazley suggested that Tleson and the Tleson painter may be identical. There is no proof for this hypothesis. Some of Tleson’s pots were painted by other artists, such as Oltos and the Centaur Painter.
