Abstract
At 1.817-921, Manilius appears to combine the Pythagorean view of comets with a different theory that enjoyed great popularity in Augustan Rome, i.e. that of attraction by sunbeams (cf. Plin. NH 2.94). At any rate, Manilius’ ideology is quite similar to the conception of the relation between astronomy and astrology attested in the Corpus Hermeticum.
