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 craftsmanship': perfectionist). His reputation in the 2nd century AD was reported in an aside by Pausanias as one "although not of the first rank of artists, was yet of unparalleled cleverness, so that he was the first to drill holes through stones"—that is, in order to enhance surface effects of light and shade in locks of hair, foliage and other details. Thus it is reported that Callimachus was known for his penchant for elaborately detailed sculptures or drapery, though few securely attributed works by him survive.
