Callimachus was an ancient Greek poet, scholar, and librarian who was active in Alexandria during the 3rd century BC. A representative of Ancient Greek literature of the Hellenistic period, he wrote over 800 literary works, most of which do not survive, in a wide variety of genres. He espoused an aesthetic philosophy, known as Callimacheanism, which exerted a strong influence on poets of the Roman Empire and, through their reception, on later Western literature. 320 BC – 240 BC; died at about 80. Alive at the same time as Archimedes, Qin Shi Huang, Epicurus, Apelles, and Euclid. Wiki link
