Book excerpt: Translated from Latin manuscripts within the British Library, the Key of Solomon was translated and then published by S. L. MacGregor Mathers in 1889. L. W. de Laurence then went on to publish his own in edition in 1914. This edition was directly based on Mathers' edition, to which he made several alterations in order to advertise his mail-order business. These advertisements have been omitted from this edition as their value today is worthless, however, the work itself is still important and so has been left untouched.
