Weather lore in Aratus' Phaenomena
Aratus was a Greek poet who flourished in the first half of the third century B.C. His poem, the Phaenomena, 1154 lines written in the epic manner, was composed about 275 B.C. and became famous in both Greek and Roman antiquity, though it has been much neglected in modern times. The title means literally "appearances", but the word became specialised in the sense of celestial appearances, the subject-matter of astronomy.
