What is "lysippides"

The Lysippides Painter worked in Athens in the second half of the 6th century BC. He was a black-figure painter of a classic style. He most probably trained with Ezekias in his workshop until moving to the Andokides workshop where he mainly painted large, expensive vases and did some work on bilingual vases with Andokides P being the red-figure painter. He was named, after much debate ensuring he was not the Andokides Painter using red-figure, after a Kalos found on one of his vases.
