The Sign of the wheel was a gesture found in an alternate where the Great Black Deaths killed 4/5 of the population of Europe. In response to the despair of the Deaths, a man called Henri appeared in France, who preached patience and a better world. When he claimed he was the Second Son of God, the King of France, and the Pope ordered Henri tortured and broken on the wheel.
The King and the Pope died the next day in a freak accident, which confirmed in the minds of many that Henri had indeed been the Second Son of God. The people of the rump French Kingdom of Versailles began to make the sign of the wheel, tracing a circle above their hearts instead of the sign of the cross. The people of the Germanies made the sign in the opposite direction, which just proved their stupidity in the minds of the French.
