Callimachus (third century BCE) authored Hymns and Epigrams. The monodrama Alexandra is attributed to his contemporary, Lycophron. Phaenomena, a poem on star constellations and weather signs by Aratus (c. 315–245 BCE), was among the most widely read in antiquity and one of the few Greek poems translated into Arabic.

Callimachus of Cyrene, 3rd century BCE, became after 284 a teacher of grammar and poetry at Alexandria. He was made a librarian in the new library there and prepared a catalogue of its books. He died about the year 240. Of his large published output, only 6 hymns, 63 epigrams, and fragments survive (the fragments are in Loeb no. 421). The hymns are very learned and artificial in style; the epigrams are good (they are also in the Loeb Greek Anthology volumes).

Lycophron of Chalcis in Euboea was a contemporary of Callimachus in Alexandria where he became supervisor of the comedies included in the new library. He wrote a treatise on these and composed tragedies and other poetry. We possess Alexandra or Cassandra wherein Cassandra foretells the fortune of Troy and the besieging Greeks. This poem is a curiosity—a showpiece of knowledge of obscure stories, names, and words.

Aratus of Soli in Cilicia, ca. 315–245 BCE, was a didactic poet at the court of Antigonus Gonatas of Macedonia, where he wrote his famous astronomical poem Phaenomena (Appearances). He was for a time in the court of Antiochus I of Syria but returned to Macedonia. Phaenomena was highly regarded in antiquity; it was translated into Latin by Cicero, Germanicus Caesar, and Avienus.
