Note 1010 — Chapter IX · THE LANDS
Reading edition
Liebrecht, Gervasius von Tilbury, 1856, p. 107, note, shows that this story and others like it were common in the Middle Ages. He cites an analogous South Russian legend of twelve miraculous wind-blown horns which keep Gog and Magog at bay and will continue to do so until the horns shall have been silenced either by birds building nests in them or else by falling to the ground. When this occurs the hordes of Gog and Magog will come forth and destroy the world.
