"Etteilla", the pseudonym of Jean-Baptiste Alliette (1 March 1738 – 12 December 1791), was the French occultist and tarot-researcher, who was the first to develop an interpretation concept for the tarot cards and made a significant contribution to the esoteric development of the tarot cards to a wide audience (from 1783), and therefore the first professional tarot occultist known to history who made his living by card divination. Etteilla also influenced the French divination professional Marie Anne Lenormand. In the years 1783–1785 Etteilla published his work Manière de se récréer avec le jeu de cartes nommées tarots ("Way to recreate yourself with the deck of cards called tarots"), which is still considered the standard reference work of Tarot cartomancy. Etteilla published his ideas of the correspondences between the tarot, astrology, and the four classical elements and four humors, and in 1789 he published his own tarot deck, which, however, differed significantly from the classic tarots such as the Tarot de Marseille in terms of structure and card designations. Personal life Aside from the birth certificate recording his birth in Paris in 1738, very little is known about Jean-Baptiste Alliette's youth. His father was a maître rôtisseur, a caterer, and his mother was a seed merchant. He married Jeanne Vattier in 1763, a marriage that lasted half a decade, during which he worked as a seed merchant, before publishing his first book, Etteilla, ou maniere de se récréer avec un jeu de cartes ("Etteilla, or way to recreate yourself with a deck of cards") in 1770. Etteilla is simply the reverse of his surname. Works Etteilla, ou maniere de se récréer avec un jeu de cartes (1770) was a discourse on the usage of regular playing cards (the piquet deck, a shortened deck of 32 cards used in gaming, with the addition of an "Etteilla" card). Features included the "spread", or disposition on the table, and strictly assigned meanings to each card both in regular and in reversed positions, characteristics that are still central to tarot divination today. In his preface, "Etteilla" explained that he had learned his system from an Italian; it remains unclear to what extent his assigned symbology was his own contribution. The book was reprinted the following year. He was working as a printseller, but from this time, approximately, he earned his livelihood by working as a consultant, teacher and author.
