Abstract

In this paper we examine some of the astrological content in Proclus' exegesis of the 'nuptial number' in Republic 545d, ff. The downfall of the best city-state is said by Socrates to be due to the fact that the Guardians, for all their wisdom, make a mistake about the timing of the breeding of future rulers and this mistake is somehow due to perception. We argue that Proclus' Republic Commentary is best understood as supposing that the Guardians are highly capable astrologers who can -- up until one fateful day -- reliably hit the astrological trifecta: they combine conception astrology with natal and katarchic astrology. The marriage festivals are timed so that future Guardians are conceived under the right stars, with pregnancies of the right duration, and are born under the right stars, with guardian daemons whose names and natures are known through an astrologically-oriented theurgic practice. All this (and more) Proclus took to be hinted at through Socrates' opaque specification of the marriage number.
