He's not even mentioned!

For all of the empire’s grand claims for the emperor, he is not worthy even to be named but only to take his place in the shadow of the exalted Jesus of the Johannine prologue. Readers of John's Gospel are invited to embrace this exalted view of Jesus. As they encounter the words and works of Jesus in the Gospel narrative they are prepared by the prologue to understand that the work of Jesus as agent of God had its origins in the mythic past, before Rome, before Moses, before Abraham—“in the beginning.”—Matthew Gordley, New Testament Christological Hymns, p. 177
