Christ holding a red banner. 1100?
Frequently confused with the Gonfalon.
The gonfanon is flown from a vertical staff and has tails on the fly. The difference between a gonfanon with long tails and a standard is that a gonfanon displays the device on the non-tailed area, and the standard displays badges down the whole length of the flag.
