Dieudonné de Gozon

He carried the nickname Extinctor Draconis, which means "The Dragon Slayer" in Latin.

In 1347 and 1348, Gozon led his order in a march to aid King Constantine V of Armenia, who was threatened by the army of the Sultan of Egypt.

Despite the orders of the previous Grand Master not to disturb the beast, Gozon slew the dragon and hung the head on one of the seven gates of the medieval town of Rhodes.

[citation needed] However, the Museum of the Order of St. John, in a 2015 article, states that there is no mention by any author of such a trophy on display before a 17th-century travelogue, which was written centuries after the head was supposedly hung on a gate at Rhodes.

[1] Historian Frederick William Hasluck suggests that Gozon's participation in a then-common Rogation festival, in which a facsimile of a dragon was "slain" to represent defeat of a symbolic "Spirit of Evil," may have evolved over time into a story where Gozon slew an actual, living dragon.
