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 (Antikensammlung F 2264) and a cup in Tarquinia (Museo Nazionale Tarquiniese RC 6848), are signed by him as painter. Overview Oltos is thought to have begun his career in the workshop of the potter Nikosthenes. Initially, he mainly painted bilingual vases or bowls with interior black-figure and exterior red-figure decoration. His black-figure style was influenced by Psiax and the Antimenes Painter. No pure black-figure works by Oltos are yet known. His tondos usually depict a single figure. They are often full of tension, frequently with differential directions of gaze and movement. Later, he exclusively painted red-figure, influenced especially by the Andokides Painter as well as several members of the Pioneer Group, especially his former pupil Euphronios. His drawing style was spacious and elegant, but never reached the depth of detail of his most important contemporary masters. He had a distinctive tendency towards luxurious ornamentation and symmetric compositions. In the middle of his career he concentrated especially on the depiction of mythological scenes. Over time, he worked with several different potters. We know of at least six: Hischylos, most importantly Pamphaios, with whom he created the earliest known stamnos, Tleson, Chelis, and finally Kachrylion, for whom he worked together with Euphronios, as well as Euxitheos. An innovation introduced by Oltos is found on an amphora at London (British Museum E 258). Here, he depicts a single figure, with no frame or floor line.
