Two gates of Sleep there are, whereof the one, they say, is horn and offers a ready exit to true shades, the other shining with the sheen of polished ivory, but delusive dreams issue upward through it from the world below. Thither Anchises, discoursing thus, escorts his son and with him the Sibyl, and sends them forth by the ivory gate: Aeneas speeds his way to the ships and rejoins his comrades; then straight along the shore he sails for Caieta’s haven. The anchor is cast from the prow; the sterns stand ranged on the shore.
