Waterhouse was one of the last of the Pre-Raphaelite Brotherhood. This image of The Lady of Shalott entitled I am half-sick of shadows, said the Lady of Shalott was the last of three on the subject Waterhouse would do and dates to 1915. It displays a lot of similarities with his Penelope and the Suitors of 1912.
The subject is taken from theTennyson poem of the same name which in turn based on Elaine of Astolat. Interestingly Tennyson would include the story, using Elaine of Astolat directly, in The Idylls of the King.
