Writings

Several poetical works on various subjects, as well as a number of prose epistles, are attributed to Aratus, but none of them have come down to us, except his two astronomical poems in hexameter. These have generally been joined as parts of the same work; but they seem to be distinct poems, the first, called ''Phenomena'' ("Appearances"), consists of 732 verses; the second, ''Diosemeia'' ("On Weather Signs"), of 422 verses.

''Phenomena''

The ''Phenomena'' appears to be based on two prose works—''Phenomena'' and ''Enoptron'' (Ἔνοπτρον, "Mirror", presumably a descriptive image of the heavens)—by

. From the lack of precision in the descriptions, it would seem that Aratus was neither a mathematician nor observer or, at any rate, that in this work he did not aim at scientific accuracy. He not only represents the configurations of particular groups incorrectly, but describes some phenomena which are inconsistent with any one supposed latitude of the spectator, and others which could not coexist at any one epoch. These errors are partly to be attributed to Eudoxus himself, and partly to the way in which Aratus has used the materials supplied by him. Hipparchus (about a century later), who was a scientific astronomer and observer, has left a commentary upon the ''Phenomenas'' of Eudoxus and Aratus, accompanied by the discrepancies which he had noticed between his own observations and their descriptions.
