     Ecco, ridente in cielo spunta la bella aurora, e tu non sorgi ancora e puoi dormir cosi'?

     (please add an English translation of this quotation)

From an a-extension of Proto-Indo-European *h₂éwsōs (“dawn”) (as Flōra from flōs, from *h₂ews- (“east”). In the Proto-Indo-European religion it was personified as the goddess of the dawn, corresponding to the Roman goddess Aurōra. De Vaan suggests that the term passed through a Proto-Italic intermediary *auzōs.^[1] However, the EIEC suggests a Proto-Indo-European form *h₂éwsōseh₂, implying that—according the EIEC—the a-extension could have already occurred before the Proto-Italic period.^[2] Cognates include the Latin auster, Ancient Greek ἠώς (ēṓs), Sanskrit उषस् (uṣás, “dawn”, “Ushas”), and the English east.
