Being catasterized is a very good thing, whether in ursified form or not. Just ask the lock of Berenike II, celebrated by Callimachus and Catullus’ translation. Incidentally, a recently published poem written after the death of Nero’s wife Poppaea (as in L’incoronazione di Poppea) gives a wondrous account of her apotheosis, swept up by Aphrodite to the gods and through the zodiacal constellations and beyond, going the apotheosis of the Ptolemaic queens one better. There, up in space, she awaits her beloved husband, who it is to be presumed would join her after his apotheosis.
The clause is a characteristic piece of Ovidian wit, set up by the earlier part of the couplet. I wouldn’t agree it’s obscure, not in the slightest. sola gives added point. It’s so un_fair_.
Surely there’s nothing “arbitrary” about Juno’s punitiveness, either. It’s systematically directed against all who receive her husband’s lecherous attentions. Callimachus’ Hymn to Delos, his very best poem in my opinion, has her suddenly relinquishing her anger against Asterie (Delos-to-be), who alone had dared to defy the goddess by giving refuge to Leto, because Asterie, unlike Leto, had successfully resisted Zeus’ advances (she “chose the sea over Zeus”). It’s a delectable para prosdokian. (I should have given a spoiler alert.)
