300 BC-Callimachus

Callimachus (/kæˈlɪməkəs/; Greek: Καλλίμαχος, Kallimakhos; 310/305–240 BC^[1]) was a native of the Greek colony of Cyrene, Libya.^[2] He was a noted poet, critic and scholar at the Library of Alexandria and enjoyed the patronage of the Egyptian–Greek Pharaohs Ptolemy II Philadelphus^[3] and Ptolemy III Euergetes. Although he was never made chief librarian, he was responsible for producing a bibliographic survey based upon the contents of the Library. This, his Pinakes, 120 volumes long,^[4] provided the foundation for later work on the history of ancient Greek literature. As one of the earliest critic-poets, he typifies Hellenistic scholarship.
