Callimachus was polemarch in Athens in 490 BC, and was one of the commanders at the Battle of Marathon.

Callimachus (Greek: Καλλίμαχος) was an architect and sculptor working in the second half of the 5th century BC in the manner established by Polyclitus. He was credited with work in both Athens and Corinth and was probably from one of the two cities. According to Vitruvius (iv.1), for his great ingenuity and taste the Athenians dubbed Callimachus katatêxitechnos (literally, 'finding fault with one's own craftmanship': perfectionist).
