The ankh was one of the few ancient Egyptian artistic motifs that continued to be used after the Christianization of Egypt during the 4th and 5th centuries AD.[30] The sign resembles the staurogram, a sign that resembles a Christian cross with a loop to the right of the upper bar and was used by early Christians as a monogram for Jesus,[31] as well as the crux ansata, or "handled cross", which is shaped like an ankh with a circular rather than oval or teardrop-shaped loop.[32] The staurogram has been suggested to be influenced by the ankh, but the earliest Christian uses of the sign date to around AD 200, well before the earliest Christian adoption of the ankh.[33] The earliest known example of a crux ansata comes from a copy of the Gospel of Judas from the 3rd or early 4th century AD. The adoption of this sign may have been influenced by the staurogram, the ankh, or both.[32]
