English poet and historical novelist whose ability to bring the ancient world to life in fiction makes his work especially appealing to young readers. As a poet he—together with J.F. Hendry—was a founder of the New Apocalypse movement, a reaction against the politically oriented, machine-age literature and realist poetry of the 1930s.

Treece was educated at Birmingham University. He became a schoolteacher, and later he served as intelligence officer in the Bomber Command during World War II. After the war he resumed writing—verse, drama, short stories, British Broadcasting Corporation scripts, as well as poetry. His most important collections of verse are The Black Seasons (1945) and The Exiles (1952). In fiction perhaps his finest achievement is The Bronze Sword (1965), a romantic “eyewitness” account of Celtic Britain's history from the Bronze Age to the decline of the Cymry under the legendary King Arthur. His historical novels include The Eagles Have Flown (1954), Red Queen, White Queen (1958), and his last novel, The Green Man (1966). He also wrote for children.
