The chronicler John of Worcester relates under the year 1099 that St Michael's Mount was located five or six miles (10 km) from the sea, enclosed in a thick wood, but that on the third day of November the sea overflowed the land, destroying many towns and drowning many people as well as innumerable oxen and sheep; the "Anglo-Saxon Chronicle" records under the date 11 November 1099, "The sea-flood sprung up to such a height, and did so much harm, as no man remembered that it ever did before". The Cornish legend of Lyonesse, an ancient kingdom said to have extended from Penwith toward the Isles of Scilly, also talks of land being inundated by the sea.
