Lumen de Lumine

Much indeed might be spoken concerning these Mountains, if it were lawfull to publish their Mysteries, but one thing I shall not forbeare to tell you. They are very dangerous places after Night, for they are haunted with Fires, and other strange Apparitions, occasion'd (as I am told by the Magi) by certaine spirits, which dabble lasciviously with the sperm of the world, and imprint their Imaginations in it, producing many times fantastic, and monstrous Generations. The Accesse and Pilgrimage to this place, with the Difficulties which attend them, are faithfully, and magisterially described by the Brothers of R. C. Their Language indeed is very simple, and with most men perhaps contemptible: But to speake finely was no part of their Designe, their Learning lyes not in the Phrase, but in the Sense, and that is it, which I propose to the Consideration of the Reader.
