“The Rape of the Lock” and the graceful romance of “Undine” have familiarised every one with the doctrine of elementary spirits; but the chief philosophical, or pseudo-philosophical, account of these unseen but not extra-mundane intelligences has been the little book of the Comte de Gabalis, a series of conversations on the secret sciences. It is generally unknown that this work is little more than an unacknowledged translation of “The Key to the Cabinet of the Chevalier Borri, wherein may be found various epistles--curious, scientific, and chemical--with politic instructions, matters which deserve well of the curious, and a variety of magnificent secrets.”[AI] Borri, who appears to have been a microcosmic precursor of Cagliostro, was born at Milan in 1627. Some proceedings of an equivocal nature caused him, in his earlier years, to seek sanctuary in a church, but subsequently, like Joseph Balsamo, he underwent a complete transformation, announced that he was inspired of Heaven, that he was elected by the omnipotent God to accomplish the reformation of mankind, and to establish the _Regnum Dei_. There should be henceforth but a single religion, with the Pope as its head, and a vast army, with Borri as general, for the extermination of all anti-catholics. He exhibited a miraculous sword which St Michael had deigned to present him, declared that he had beheld in the empyrean a luminous palm-branch reserved for his own celestial triumph, announced that the Holy Virgin was divine by nature, that she conceived by inspiration, that she was equal with her Son, and was present in the Eucharist with him, that the Holy Spirit had taken flesh in her person, that the second and third persons of the Trinity are inferior to the Divine Father, that the fall of Lucifer involved that of a vast number of angels, who now inhabit the regions of the air, that it was by the intervention of these rebellious spirits that God created the world and gave life to all beasts, but that men were in possession of a Divine soul which God made in spite of himself. Finally, with a contradiction more French than Italian, he gave out that he was himself the Holy Spirit incarnate.
