The cataclysm of 2194 BC, as described in the Oera Linda Book, seems to have submerged some low-lying lands in the North Sea that extended out from the present Frisian Islands, including a large island known as Atland, or Aldland (‘old land’), now the Dogger Bank. Atland was regarded as the original homeland of the Frisians, as is clearly implied by the repeated references to it in the Oera Linda Book. Confusion has arisen, however, because the homeland, or ald-lând, of the Finns also perished during the same series of natural disasters.
By the late 1960s the mill was in such a bad state of repair that Birmingham City Council decided to demolish it. A local campaign was launched to prevent this, to which Tolkien contributed financially from the proceeds of The Lord of the Rings, which was now becoming a worldwide bestseller and cultural phenomenon. So, coming full circle in this way, Sarehole Mill was opened as a working museum in 1969.
