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" took 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 (or author Mark Falstein) may have mistakenly translated Logres as Great Britain, perhaps expressing the misconception that Britain equals England.
