The coat of arms representing the grandmaster ("Hochmeisterwappen") is shown with a golden cross fleury or cross potent superimposed on the black cross, with the imperial eagle as a central inescutcheon. The golden cross fleury overlaid on the black cross became widely used in the 15th century. A legendary account attributes its introduction to Louis IX of France, who is said to have granted the master of the order this cross as a variation of the Jerusalem cross, with the fleur-de-lis symbol attached to each arm, in 1250. While this legendary account cannot be traced back further than the early modern period (Christoph Hartknoch, 1684), there is some evidence that the design does indeed date to the mid 13th century.
