The Gaelic Maundeville (Author: John Maundeville)

paragraph 240

I myself was one day traversing that sea of India, and I saw before me on the main a great wood covered with leaves. And I asked what that wood was, and whence was the earth under it, and thus the ship's crew told me, that once upon a time a great fleet had come there, in the ships whereof were nails of iron: so the rocks of adamant that were in the sea drew the ships to them down into the bottom, and in these ships were some fruits whereout that wood had grown.
