Under whitespread wings like he'd come from Arkangels

• As Zeus about to rape Leda or the Gabriel Archangel / Holy Spirit about to ??? the Virgin Mary

• Arkangels --> arc-en-ciel (Fr. for 'rainbow); there is the Bifrost in Norse mythology, the rainbow-bridge that unites the Earth with Asgård and can be only traversed by gods, so if you happen to see someone coming from it you know is important.

• From Tennyson's "Dying Swan":

    with an inner voice the river ran,
    adown it floated a dying swan
