Gildas Gildas (Breton: "Gweltaz", c. 500–570) — also known as Gildas the Wise or Gildas Sapiens — was a 6th-century British monk best known for his scathing religious polemic "De Excidio et Conquestu Britanniae", which recounts the history of the Britons before and during the coming of the Saxons. He is one of the best-documented figures of the Christian church in the British Isles during the sub-Roman period, and was renowned for his Biblical knowledge and literary style. In his later life, he emigrated to Brittany where he founded a monastery known as St. Gildas de Rhuys.
Annalists Annalists (from Latin "annus", year; hence "annales", sc. "libri", annual records), were a class of writers on Roman history, the period of whose literary activity lasted from the time of the Second Punic War to that of Sulla. They wrote the history of Rome from the earliest times (in most cases) down to their own days, the events of which were treated in much greater detail. Annalists were different from historians, in that an annalist was more likely to just record events for reference purposes, rather than offering their own opinions of events. There is, however, some overlap between the two categories and sometimes annalist is used to refer to both styles of writing from the Roman era.
