"The moon was a ghostly galleon tossed upon cloudy seas"
"The wind was a torrent of darkness among the gusty trees"
"The highwayman came riding, riding--
Up to the old inn-door"
"Her face was a mask of terror, blanched as a white sheet"
"The moon like a ghostly galleon rose through the misty skies"
These comparisons using "like" or "as" create vivid imagery and enhance the poetic atmosphere of the poem.
