the gates

"Ah my friend," seasoned Penelope dissented,
"dreams are hard to unravel, wayward, drifting things--
not all we glimpse in them will come to pass...
Two gates there are for our evanescent dreams,
one is made of ivory, the other made of horn.
Those that pass through the ivory cleanly carved
are will-o'-the-wisps, their message bears no fruit.
The dreams that pass through the gates of polished horn
are fraught with truth, for the dreamer who can see them..."

-- Homer The Odyssey
