What is "luison"

Luison, Luisõ or Lobison is the name of a monstrous creature from Guaraní mythology. Being one of the seven cursed children of Tau and Kerana, the Luison is one of the primary figures of legend in Guaraní-speaking cultures today, such as Paraguay. Of the original myths of the Guaraní people, the Luison is one of the few whose story has changed significantly in modern times.

The name of Luison is a variation of Lobizón, a name used in Uruguay to describe the werewolf or a similar creature, which is itself a variation of the Brazilian name for the werewolf, Lobisomem, more literally wolf-man. What name Luison may have had prior to the influence of European-based mythology is likely lost to the world. Guaraní was not a written language and all myths passed on in storytelling only, thus no written record of his original name would have been made.
