Go write yourself a book

Go write yourself a book and put
therein first things that might define a world:

There's a great clock upon which the pole star
will return, turn,
and return. Cheops' stone mountain's
a lyric gesture. Homer
underwrites not adventure
but the way back home
before Odysseus may shed
a life's disguise.
