Flaminius Annibali de Latera (born at Latera, near Viterbo, 23 November 1733; died at Viterbo, 27 February 1813) was an Italian historian. He received his first education from a priest, Paolo Ferranti, and at the age of sixteen entered the Order of Friars Minor Observants in the Roman Province, taking the habit at the convent of St. Bernardine at Orte, 23 January 1750; a year later on the same day he made his solemn profession. Being in due time ordained priest, he passed his examinations as lector generalis (professor), and successively taught theology in various convents — Viterbo, Fano, Velletri, and Rome.
