1. I have been unable to understand the construction “Ὑάσι καὶ Πλειάσιν”. The Hyades and Pleiades seem to be meant, but surely these words are verbs? Is there some contraction here?
One problem I have faced throughout is ἀνατέλλει, which makes “it rise”. It appears in Matthew 5:45, τὸν ἥλιον αὐτοῦ ἀνατέλλει ἐπὶ πονηροὺς καὶ ἀγαθοὺς (His sun He does cause to rise on evil and good). But Antiochus equally uses ἐπιτέλλει, seemingly in much the same sense. So … why use both?
Possibly the answer is found here, in material from Hippocrates, Airs Waters Places, at Perseus, where a calendar from Aetios is given:
Spring began with the equinox, but was often popularly dated from the appearance of swallows and the acronychal rising of Arcturus in February. The heliacal rising of the Pleiades marked the beginning of summer, which ended with that of Arcturus, an event nearly coinciding with the autumnal equinox. Finally, winter began with the cosmic setting of the Pleiades.
A star is said to rise heliacally when it gets far enough in front of the sun to be visible before dawn. It sets cosmically when it gets so much further in advance as to be first seen setting in the west before dawn. The acronychal is the evening rising of a star, when it is visible all night, and contrasts with the heliacal, or morning, rising, when it soon disappears in the sun’s rays.
Ouch. Here we’re getting into some astronomical jargon. But in that calendar ἐπιτέλλει is used at least once for “heliacal rising.” Interestingly it appears on the Antikythera mechanism.
