The basis of absolute hieroglyphical science was an alphabet in which deities were represented by letters, letters represented ideas, ideas were convertible into numbers, and numbers were perfect signs. This hieroglyphical alphabet was the great secret which Moses enshrined in his Kabalah; its Egyptian origin is commemorated in the _Sepher Yetzirah_, in which it is referred to Abraham. Now this alphabet is the famous Book of Thoth, and it was divined by Court de Gebelin that it has been preserved to our own day in the form of Tarot cards. It passed later on into the hands of Etteilla, who interpreted it in the wrong sense, for even a study extending over thirty years could not atone for his want of common sense or supply deficiencies in his education. The record exists still among the drift and waste of Egyptian monuments; and its most curious, most complete key is found in the great work on Egypt by Athanasius Kircher. It is the copy of an Isiac tablet which belonged to the celebrated Cardinal Bembo. The tablet in question is of copper with figures in enamel, and it has been unfortunately lost. The copy supplied by Kircher is, however, exact.[49] The learned Jesuit divined that it contained the hieroglyphic key of sacred alphabets, though he was unable to develop the explanation. It is divided into three equal compartments; above are the twelve houses of heaven and below are the corresponding distributions of labour throughout the year, while in the middle place are twenty-one sacred signs answering to the letters of the alphabet. In the midst of all is a seated figure of the pantomorphic IYNX, emblem of universal being[50] and corresponding as such to the Hebrew _Yod_, or to that unique letter from which all other letters were formed. The IYNX is encircled by the Ophite triad, answering to the Three Mother Letters of the Egyptian and Hebrew alphabets.[51] On the right are the ibimorphic and serapian triads; on the left are those of Nepthys and Hecate, representing active and passive, fixed and volatile, fructifying fire and generating water. Each pair of triads in conjunction with the centre produces a septenary, and a septenary is contained in the centre. The three septenaries furnish the absolute number of the three worlds, as well as the complete number of primitive letters, to which a complementary sign is added, like zero to the nine numerals. The ten numbers and the twenty-two letters are termed in Kabalism the Thirty-two Paths of Wisdom, and their philosophical description is the subject of that venerated primæval book known as the _Sepher Yetzirah_, the text of which will be found in the collection of Pistorius and elsewhere.[52] The alphabet of Thoth is the original of our Tarot only in an indirect manner, seeing that the latter is of Jewish origin in the extant copies and that its pictures are not older than the reign of Charles VII. The cards of Jacquemin Gringonneur are the first Tarots of which we have
