Oltos was a Late Archaic Greek vase painter, active in Athens from 525 BC to 500 BC. About 150 works by him are known. Two pieces, a cup in Berlin and a cup in Tarquinia, are signed by him as painter.

Nikosthenes was a potter of Greek black- and red-figure pottery in the time window 550–510 BC. He signed as the potter on over 120 black-figure vases, but only nine red-figure. Most of his vases were painted by someone else, called Painter N. Beazley considers the painting "slovenly and dissolute;" that is, not of high quality. In addition, he is thought to have worked with the painters Anakles, Oltos, Lydos and Epiktetos. Six's technique is believed to have been invented in Nikosthenes' workshop, possibly by Nikosthenes himself, around 530 BC. He is considered transitional between black-figure and red-figure pottery.
