This emblem inspired the shape of the beautiful Etruscan funeral vase, which is in itself symbolical and derived from the worship of the Assyrians. He is frequently represented by a cup or chalice, since Mercury was also the cup bearer of the gods, like the butler of the Pharaoh (Genesis xl), who protected his master from poison. When he was the messenger he held to the lips of mortals the seven-ringed cup of sorrow or joy, and the many significances of this cup, although now nearly forgotten, were realised by the ancient worshippers as an important emblem of the functions of the god.

If the Tarots are the direct descendants of the occult images in the Temple of Thoth, as is conceded, it must also be acknowledged that then these cards each has a meaning or intention worth studying, if only to discover their secret; and that if they are connected with the ancient mysteries they represent human life in all its phases. To wrest their secret from them has been the endeavor of many writers, some of whom have learned their portent traditionally, others through careful historical investigation, while some confess to inspiration without authority or support, but not one of these authors discovered the important connection between the emblems on the cards and those representing Mercury heraldically under his chief guises, although such a discovery would have been conclusive proof that their surmises were correct and that cards were the survival of the cult of Mercury and his predecessors.

Nevertheless, a thorough examination of all these writers shows that through different channels they all come to the same conclusions, and by comparing their writings with that of the original rules for the game of l’Ombre (or The Man) quite a definite idea of the value and meaning attached to each card by the initiates or priests of Mercury may be reached.

Raymond Lulle (1235-1315) gives an historical account of Tarots in his “Ars Magna.” Jerome Cardeau (1501-1576) writes of the historic pack in his work “Subtility.” An English writer named Mathers has written exhaustively about the great book of Thoth Hermes Trismegistus, chiefly with the view of explaining fortune-telling through a correct reading of the mysterious leaves.

Court de Gebelin, although sneered at by the authors who followed him, who found his learning too deep for their understanding, has given a lucid account of Tarots and their connection with divination, while Boiteau, in his “Les Cartes à Jouer et la Cartomancie”; Merlin, in his “Origin des Cartes”; Chatto, in his “Facts and Speculations About Cards,” and Taylor, in his “History of Playing Cards,” agree that cards appeared suddenly in Europe early in the fourteenth century, that the cards of that day were the Tarots, or the fortune-telling cards, that they were altered to suit Dutch, Swedish or German tastes, or the fancies of a French king, following also the desires of each nation that adopted them for gambling purposes, with no thought of the ancient cult to which they had belonged. Not one of them, however, pointed out the connecting link with the emblems of Mercury, or explained the reason for this sudden appearance in civilised nations of these fortune-telling packs, except De Gebelin, while even he failed to connect the attributes of Mercury with the pips on the cards or the emblematic figures on the Atouts that still show the attributes of the chief gods of Egyptian mythology, that would have been such convincing proofs of their origin.

We are indebted to Papus, in his “Tarots of the Bohemians,” for clearly pointing out that the cards are derived from the book of Thoth and for explaining the meaning of each leaf. But even Papus, shrewd and far-seeing as he is, does not bridge the chasm lying between the temples of the Egyptian deities and the introduction of cards into Europe, although he recognises the paramount importance of the emblem of Rods, which he wisely calls Sceptres, since he sees the value that such a symbol of power was to the ancients, and he never condescends to call the pip by its vulgar name of Club.

It is the more strange that the surviving signs connecting the ancient worship of Mercury with the emblems on the pip cards remained unnoticed, for the old Temple of Mercury at Baiæ remains with its vaulted roof in a fairly good state of preservation; and on the ceiling of this temple can still be seen traces of pictures resembling those on the Atouts. Almost obliterated and difficult to see, since the place is dark and there is no means of lighting, they can yet be discerned, even though it would be impossible to reproduce the emblems.

They are in the shape of the old Atouts, that is to say, the figures are enclosed in a well-defined line the shape of a card, and the same size if considered in reference to that of the emblematic pictures. Two of them are distinct enough to show a figure, although which one of the Atouts is intended it is now impossible to say. Traces of other Atouts may be discerned all along the roof of the building, although they are being rapidly destroyed by the weather.

Enough evidence exists now to show that, in this house erected to Mercury by the rich merchants of Rome, the emblematic figures were displayed as ornaments on the ceiling and were not concealed in alcoves or curtained niches, which some writers have supposed was done in the more ancient temples of Egypt where pictures have been discovered that have puzzled the savants who have not connected them with the worship of Thoth or Serapis.

Why the emblems of Mercury did not receive recognition from the authorities on playing cards of the past three centuries, or from others, remains a mystery, since it seems to be quite evident that, while the Atouts show the various virtues, vices, arts and crafts, which were under his protection, the pip cards display his four chief attributes, and that these were evidently placed in the book to represent the god when it was necessary to call on his good offices to protect or guide merchants, to direct love affairs, to encourage warriors or to inspire scientists. No other derivation for these devices has even been suggested, and these self-evident links in the chain of evidence connecting playing cards with the worship of Mercury have been totally ignored. Many students have, however, pointed out that the Tarots are the survivors of his cult and were originally the Book of Thoth Hermes Trismegistus.
