Hugo Falcandus was a historian who chronicled the reign of William I of Sicily and the minority of his son William II in a highly critical work entitled The History of the Tyrants of Sicily (or Liber de Regno Sicilie). The Latin of the work is polished. There is some doubt as to whether "Hugo Falcandus" is a real name or a pseudonym. Evelyn Jamison argued that he was Eugenius, amiratus from 1190. The Frenchman Hugues Foucaud (Hugo Fulcaudus), abbot of Saint-Denis, has been proposed as an author. His name, Falcandus, is apparently a cacography for Falcaudus, Latin for "Foucaud", a French surname.
