The last sentence probably refers to the arrangement of these vowels often met with in inscribed Gnostic talismans, the so-called Abraxas gems. Here we often find them in the following order Ι Ε Η Θ Ο Υ Α, and the sound of these vowels really suggests the conventional pronunciation of the Hebrew name Jehovah (yehowah). The words quoted from the Pistis Sophia are placed in the mouth of Jesus, and King calls attention to the fact that in Greek the same word is used for voice and vowel (φώνη). He therefore believes that the passage in Revelations (x, 3–4): “The seven thunders uttered their voices,” signifies that the sound of the seven vowels “echoed through the vault of heaven, and composed that mystic utterance which the sainted seer was forbidden to reveal unto mortals.” [Illustration: A MEDIEVAL SPELL From a XIV century Italian MS. in the author’s library. The efficacy of the spell is to be insured by reciting the accompanying invocation thrice. ] Certain talismans were supposed to afford protection not only to individuals but even to entire cities. Of this class were two talismans described by Gregory of Tours. He relates that Paris had enjoyed from ancient times a surprising immunity from serpents and rats, as well as from fires. However, in clearing out the channel beneath a bridge across the Seine, the workmen found, embedded in the mud, two brazen images, one of a serpent and the other of a rat; after these had been removed from their resting place, serpents and rats appeared, and conflagrations became common.[582] Of the many memorials of the Age of Charlemagne preserved in the Cathedral Treasury at Aachen, that popularly known as the Talisman of Charlemagne always exerted a peculiar fascination over the minds of those visiting the shrine, both because of its sacred character and on account of the mystic power ascribed to it. The “Talisman” is composed of two large sapphires, cut _en cabochon_, one being of oval form and the other square, these constituting respectively the front and back of the relic; enclosed between them is a cross made from wood of the Holy Cross said to have been found in Palestine by St. Helena, mother of Constantine the Great. This is only visible when looking through the oval sapphire set in front of the medallion. The two sapphires are joined and framed by a band studded with precious stones, and various other gems are set above and below them. The oval sapphire is of a pale blue, and is furnished with a gold openwork bordering. At the top of the medallion, in a square space is set a lozenge-shaped garnet, and around the oval sapphire forming the front are placed successively, (1) an emerald, (2) a pearl, (3) a garnet, (4) a pearl, (5) an emerald, (6) a pearl, (7) a garnet, (8) a pearl, (9) an emerald, (10) a pearl, (11) a garnet, (12) a pearl, (13) an emerald, (14) a pearl, (15) a garnet, (16) a pearl.
