This one came from a friend who remembers memorizing it as a kid back in elementary school. She particularly loved it due to its depiction of "the moon as an entity," and the connection she made with the stories she'd heard (She's half-Japanese) of the Rabbit in the Moon.

Silver

Slowly, silently, now the moon
Walks the night in her silver shoon;
This way, and that, she peers, and sees
Silver fruit upon silver trees;
One by one the casements catch
Her beams beneath the silvery thatch;
Couched in his kennel, like a log,
With paws of silver sleeps the dog;
From their shadowy cote the white breasts peep
Of doves in a silver-feathered sleep;
A harvest mouse goes scampering by,
With silver claws and a silver eye;
And moveless fish in the water gleam,
By silver reeds in a silver stream.
