Knights Hospitaller
The Order of Knights of the Hospital of Saint John of Jerusalem (; ), also known as the Order of Saint John, Order of Hospitallers, Knights Hospitaller, Knights Hospitalier or Hospitallers, was a medieval and early modern Catholic military order. It was headquartered in the Kingdom of Jerusalem, on the island of Rhodes, in Malta and St Petersburg.
Mythology of Carnivàle
"Carnivàle" introduces the Knights Templar, a medieval Christian military order, in the late Season 1 episode "Lonnigan, TX", where Ben meets the freak finder Phineas Boffo. When Ben comes in contact with Boffo's ring, he experiences a powerful series of visions of the Knights Templar practicing rituals, putting heads on spikes, and being burned at the stake. The ring bears a red-crossed symbol, and when Samson passes a trinket with the same symbol to Lodz, the mentalist has the same visions as Ben and falls to the floor chanting "in hoc signo vinces" ("in this sign you will conquer"). The Knights Templar remain a recurring subplot until Ben discovers the symbol's significance in early Season 2. The Lodge of the Benevolent Order of Templar has its last appearance in the mid-Season-2 episode "Old Cherry Blossom Road", where the escaped convict Varlyn Stroud uses it to track Ben. When Wilfred Talbot Smith asks for the location of the Saunière manuscript late in Season 2, Scudder answers that it is hidden in Rennes-le-Château.
