Saint Kilian
The arms come from the town's oldest known seal, from 1236. The human figure in the chief is the Bishop of Paderborn, who granted Korbach town rights in 1188, although it could be his successor Bishop Wilbrand, who had the townsfolk swear him in as their overlord in 1227. The aforesaid seal was made not long after this. There is an erroneous belief that the human figure is Saint Kilian, the town's patron saint, but this is believed to be rather unlikely, as the figure looks like a bishop.
