Waking, I half-recall the long night's dreams:
A thousand Earth-lives, while this body slept.
As Swift I knew too much, betrayed the knowledge;
As Lowell, saw too much...with yearning eyes
Saw not the night, but yesterday and tomorrow.
(Note: The references are to Jonathan Swift, who described the moons of Mars with eerie accuracy before astronomers were able to see them, and astronomer Percival Lowell, who was convinced he saw a network of Martian canals.)
