Evelyn De Morgan ( ; 30 August 1855 – 2 May 1919) was an English painter whose works were influenced by the style of the Pre-Raphaelite movement. She was a follower of Pre-Raphaelist Edward Burne-Jones. Her paintings exhibit spirituality; use of mythological, biblical, and literary themes; the role of women; light and darkness as metaphors; life and death; and allegories of war.
Evelyn De Morgan did paintings exhibiting light and darkness as metaphors for the Pre-Raphaelite movement.
While De Morgan's paintings were influenced by the Pre-Raphaelite movement, the context doesn't explicitly state that the light/dark metaphors were regarding the Pre-Raphaelite movement. They may or may not. The system probably just saw the wording and did not understand the context.
