A rood or rood cross, sometimes known as a triumphal cross, is a cross or crucifix, especially the large Crucifixion set above the entrance to the chancel of a medieval church. Alternatively, it is a large sculpture or painting of the crucifixion of Jesus.
Rood is an archaic word for pole, from Old English rōd "pole", specifically "cross", from Proto-Germanic *rodo, cognate to Old Saxon rōda, Old High German ruoda "rod".
Rood was originally the only Old English word for the instrument of Jesus Christ's death. The words crúc and in the North cros (from either Old Irish or Old Norse) appeared by late Old English; "crucifix" is first recorded in English in the Ancrene Wisse of about 1225. More precisely, the Rood was the True Cross, the specific wooden cross used in Christ's crucifixion. The word remains in use in some names, such as Holyrood Palace and the Old English poem The Dream of the Rood. The phrase "by the rood" was used in swearing, e.g. "No, by the rood, not so" in Shakespeare's Hamlet (Act 3, Scene 4).
The alternative term triumphal cross (Latin: crux triumphalis, German: Triumphkreuz), which is more usual in Europe, signifies the triumph that the resurrected Jesus Christ (Christus triumphans) won over death.
