What is "triboulet"

n. 1 A jester dressed entirely in red. 2 A tapered steel mandrel used by a jeweler to make jewelry.

Triboulet (1479–1536) was a jester of kings Louis XII and Francis I of France.

He appears in Book 3 of François Rabelais' Pantagrueline chronicles. He appears in Victor Hugo's Le Roi s'amuse and its opera version, Giuseppe Verdi's Rigoletto, a blend of "Triboulet" and French rigoler (to laugh), intended to deflect the censorship that Hugo's work had received. A triboulet, a jester dressed entirely in red, is a character associated with the carnival of Monthey in Switzerland.
