Falcandus, Hugo a distinguished historian, lived in the 12th century. According to the Benedictine authors of the work L'Art de Verifier les Dates, he was a native of France (his original name being Fulcandus or Foucault);
accompanied his patron Stephen de la Perche, archbishop of Palermo, and grand-uncle of king William II, to Sicily, and finally became abbot of St. Denys, at Paris. Gibbon is of opinion that he was a native of Sicily. His celebrated work, Historia Sicula, which procured for him the surname of the Sicilian Tacitus, was published in 1189 or 1190, and is of great importance for the Church history of that period. — Wetzer u.
