The White Ship

'The White Ship' is a horror short story by American writer H. P. Lovecraft. It was first published in The United Amateur (Volume 19), November 1919, and later appeared in the March 1927 issue of Weird Tales.
Basil Elton, a lighthouse keeper, engages in a peculiar fantasy in which a bearded man in robes is piloting a mystical white ship which appears when the moon is full. Elton walks across the water on a bridge of moonbeams, joins the bearded man on the ship, and together they explore a mystical chain of islands unlike anything that can be found on Earth.
