Guarin
Guarin (French: Guérin, Italian: Guarino, Norman: Warin) (died 21 January 1137) was the chaplain (magister capellanus) and chancellor of Roger II of Sicily from about 1130 to his death, during the first decade of the Norman kingdom of Sicily. According to Alexander of Telese, the contemporary chronicler, he was "erudite ... and most prudent in negotiations ... a cleric well-versed in letters, skillful in matters of the world, and possessed of a tenacious and cautious mind."
