magic, the followers of that art have taken an oath not to give this volume to anyone until its owner is on his death-bed, never to have more than three copies of it made at a time, and never to give it to a woman or to a man who is not of mature years and proved fidelity. Each new recipient of the sacred volume is also to take this oath. Hence the name, _Juratus_ or _Sworn-Book_. Its other titles, _Sacer_ or _Sacratus_, refer either to the sacred names of God which constitute much of its text or to its consecration by the angels. [Sidenote: _Incipit_ and _Explicit_.] After this proemium, which, like the magic art itself, is probably more impressive than true, the work proper opens with the statement, “In the name of almighty God and Jesus Christ, one and true God, I, Honorius, have thus ordered the works of Solomon in my book.” Later Honorius reiterates that he is following the precepts and in the foot-prints of Solomon, whom he also often cites or quotes in course. The _Explicit_ of the _Sworn-Book_ is unusually long and sets forth in grandiloquent style the purpose of the volume. “So ends the book of the life of the rational soul,[902] which is entitled _Liber sacer_ or _The Book of the Angels_ or _Liber juratus_, which Honorius, Master of Thebes, made. This is the book by which one can see God in this life. This is the book by which anyone can be saved and led beyond a doubt to life eternal. This is the book by which one can see hell and purgatory without death. This is the book by which every creature can be subjected except the nine orders of angels. This is the book by which all science can be learned. This is the book by which the weakest substance can overcome and subjugate the strongest substances. This is the book which no religion possesses except the Christian, or if it does, does so to no avail. This is the book which is a greater joy than any other joy given by God exclusive of the sacraments. This is the book by which corporeal and visible nature can converse and reason with the incorporeal and invisible and be instructed. This is the book by which countless treasures can be had. And by means of it many other things can be done which it would take too long to enumerate; therefore it is deservedly called _The Holy Book_.” [Sidenote: A work of theurgy or the notory art.]
