Logres

Logres was a historical name of Great Britain during the reign of King Arthur. It suffered from Saxon raids and the treachery of Mordred.

According to an Old Irish verse, "when fair Logres fell" in the 6th century, "Galhaut the Pure" brouht the Holy Grail to the monastery of Iona.

Behind the scenes
In reality, Logres refers to the region of England in Arthurian context. In the Grail Diary Henry Jones perhaps mistakenly translates Logres with Great Britain, perhaps expressing the American point of view that Britain = England.
