Who track the breezy winds and flights of birds,
On wings of swiftness hovering nigh the heaven.
Then Ceto, fair of cheek, to Phorcys bore
[171]The Graiæ; from their birth-hour gray: and hence
Their name with gods, and men that walk the earth:
Long-robed Pephredo, saffron-veil’d Enýo:
And Gorgons dwelling on the brink of night
Beyond the sounding main: where silver-voiced
Th’ Hesperian maidens in their watches sing:
Stheno, Euryale, Medusa these:
