Kritios (Ancient Greek: Κριτίος, /krɪˈtiːəs/) was an Athenian sculptor, probably a pupil of Antenor, working in the early 5th century BCE, whose manner is on the cusp of the Late Archaic and the Severe style of Early Classicism in Attica.
With Nesiotes (Νησιώτης,) Kritios made the replacement of the Tyrannicides ("Tyrant-killers") group[1] by Antenor, which had been carried off by the Persians in the first stage of the Greco-Persian Wars.
With Nesiotes Kritios made other statues, of bronze, dedicated on the Acropolis, of which only their inscribed bases remain to give testament.
Its easy naturalism and relaxed contrapposto set it apart from the Late Archaic conventional kouroi that preceded it.
