Aratus Solensis

Aratus was born around 315 BC in Soli in Cilicia (southern Turkey). He studied philosophy with Zeno of Citium, the founder of Stoicism, in Athens, and spent time at the courts of Antigonus Gonatas in Macedonia and Antiochus I in Syria. He was a man of broad culture — ancient sources mention editions of Homer and medical writings alongside his poetry.

His fame rests on a single poem: the Phaenomena, a verse account of the constellations and weather signs in 1,154 hexameters. The astronomical section follows Eudoxus of Cnidus (whose prose work is lost), while the weather signs draw on Theophrastus and folk tradition. The poem was a sensation. Callimachus praised it, Hipparchus wrote a commentary on it, Cicero translated it into Latin as a young man, and Virgil borrowed from it in the Georgics. It remained one of the most widely read poems in antiquity.

The Phaenomena is not a scientific treatise but a didactic poem in the tradition of Hesiod's Works and Days. Aratus was a Stoic, and the poem opens with a famous hymn to Zeus that sees divine providence ordering the heavens for human benefit. The stars are not just objects of knowledge — they are signs of a rational, benevolent cosmos.
