P. Vergilius Maro, Aeneid
Theodore C. Williams, Ed.

Now Sleep has portals twain, whereof the one
Is horn, they say, and easy exit gives
To visions true; the other, gleaming white
With polished ivory, the.dead employ
To people night with unsubstantial dreams.
Here now Anchises bids his son farewell;
And with Sibylla, his companion sage,
Up through that ivory portal lets him rise.
Back to his fleet and his dear comrades all
Aeneas hastes.

    Then hold they their straight course
Into Caieta's bay. An anchor holds
Each lofty prow; the sterns stand firm on shore.
