Geoffrey Gaimar

Geoffrey Gaimar (fl. 1130s), also written Geffrei or Geoffroy, was an Anglo-Norman chronicler. His contribution to medieval literature and history was as a translator from Old English to Anglo-Norman. His L'Estoire des Engleis, or History of the English People, written about 1136–1140,

Gaimar claims to have also written a version of the Brut story, a translation of Geoffrey of Monmouth's chronicle Historia Regum Britanniae (c. 1136) into Anglo-Norman verse, which was commissioned by Constance, wife of Ralph FitzGilbert, a Lincolnshire landowner. Gaimar's translation, if it existed, antedated Wace's Norman Roman de Brut (c. 1155), but no copy of Gaimar's Brut (also known as L'Estoire des Bretuns) has survived, being superseded by the latecomer. Ian Short argues that Gaimar's Estoire des Bretuns was no more than a short epitome of the pre-Arthurian section of Geoffrey of Monmouth's Historia Regum Britanniae, which might explain why Wace's later, full translation of the text became more popular and ultimately superseded Gaimer's.

Gaimar did not create two separate and distinct chronicles, and the two estoires were merely the former and latter sections of a long-running history starting from the Argonauts' quest for the Golden Fleece to the reign of William II "Rufus" (died 1100) that Gaimar set out to write.

A version of Havelok the Dane occurs at the beginning of L'Estoire des Engles, which must have originally been interpolated in between the history of the Britons and the history of the English, ) Additionally there is a mention of a sword, Calibur (Excalibur), pointing to Gaimar's knowledge of Galfridian legendary history that predated the advent of Wace's Brut.
