What has just been said leads me to remark that the phallus, which was a common form of the _genius loci_, or Agathodæmon, was widely believed to have great power to protect against harm. In it was a sovereign preventive of malign fascination, or the influence of the evil eye. The Roman god, Fascinus,[463] had it as his chief symbol. It is well known that this charm was sometimes placed on houses[464] in Pompeii, with the inscription, _hic habitat felicitas_. Aubrey says: “In the digging of the ruins and foundations of London, after the great conflagration, there were found several little Priapusses of copper, about an inch long, wᶜʰ the Romans did weare about their necks.”[465] [Illustration: FIG. 19.—THE DIVINE NAME. (As seen on a talismanic gem, copied from De Wilde’s book.)] In regard to the ΙΑΩ, JΑΩ, or JAO, a variation of JAH,[466] the name of the Deity, the demiurge, the Sabaoth of the Phœnicians and others, I may say that it was regarded as possessing in itself irresistible talismanic power. Fort remarks that “as a talisman of medical properties it was carried about the person in tubes, or, more generally, on parchment.”[467] Let me add that the Tetragrammaton—that is, J H V H, or, as it is commonly rendered, Jehovah—was the same thing as the ΙΑΩ. Much could be said about it, as those familiar with Masonic legends and occult literature are aware. Lenormant states, of the wide belief in the power of the hidden “name of the Lord,” that “we now see clearly that it came from Chaldea.”[468] Elsewhere, reference is made to the potent word which Hea bore in his heart. In this connection I may say a word on the “triliteral monosyllable” of the Brahmin and Buddhist, AUM, to which still, as in the past, great potency is attached. Being a symbol of the Supreme, it is characterized as “that which passes not away.” Dr. Birdwood remarks that it is “the identical formula of every Hindu god. The letter A is the _vija-mantra_ of the male Buddha, the generative power; U, the ditto of the female _dharma_ (law), the type of productive power; and M, the _sanga_ (congregation) or union of the essences of both.”[469] [Illustration: FIG. 20.—FORMS OF THE PRESCRIPTION SYMBOL.]
