When Moon

Epigrammata L

What song, O Luna / great scarred stone that blocks the sun / is lost in black space?

Ours is a strange moon, I say
Not quite sure how it got that way
Most moons so large have some ice
And carbon rocks, to be precise
It's not an average moon at all
A lonely creature, can we call
It a moon? Or a stone to roll
O'er a grave? To need the whole,
What was in that grave when full?
