450 – 420 BCE), a Greek vase-painter in Athens, is considered[by whom?]
one of the most important vase painters of the red figure style of the high-classical period.
He received his training in the workshop of the Niobid Painter and specialized in monumental vases, as in the manner of Polygnotos of Thasos, after whom he probably designated himself.
He was the leading vase painter of the Group of Polygnotos which carries his name.
