Tasseography

Tasseography (from the French tasse, "cup") is the art of divination by reading the patterns left by tea leaves, coffee grounds, or wine sediment in a cup. In the classic tea-leaf form, loose tea is brewed and drunk (or poured off) so that a residue of leaves remains; the drinker swirls the dregs, inverts the cup onto the saucer, and the reader then interprets the shapes the scattered leaves form against the sides and bottom of the cup, a bird, a ship, a ring, a letter, along with their position, since leaves near the rim are conventionally read as the near future or the present, and those toward the bottom as the more distant future or the deeper past.

The practice spread widely in Europe with the popularity of tea and coffee from the seventeenth and eighteenth centuries, and a comparable coffee-ground reading (tasseomancy) is deeply embedded in Middle Eastern, Balkan, and Turkish/Greek social custom, where reading the cup after coffee is a familiar domestic ritual. Nineteenth- and twentieth-century popular manuals codified dictionaries of symbols and even produced special divining cups printed with zodiac signs and meanings. Understood as a technique, tasseography works much like other forms of reading random patterns, clouds, inkblots, the crystal ball, providing an ambiguous field onto which the reader projects intuitive imagery, framed by tradition and by the sitter's situation. It endures as one of the most homely and companionable of the divinatory arts, bound up with the everyday sociability of tea and coffee.

Reading the residue in a cup requires a drink that leaves one, and the history follows the drink. Coffee reached the Ottoman world before tea reached Europe, and reading the grounds is attested there earlier; the practice remains common across Turkey and the eastern Mediterranean, with its own conventions about turning the cup and letting it cool. Tea leaf reading in Britain and Ireland becomes visible from the eighteenth century, after tea itself becomes affordable, and it flourished as a domestic and largely female practice.

Its literature is a nineteenth and twentieth century phenomenon. Cheap printed manuals set out alphabetical dictionaries of symbols, an anchor for security, a snake for an enemy, a ring for a marriage, and it is these books rather than any older tradition that fixed the meanings most readers now expect. They were sold alongside dream dictionaries and fortune-telling card manuals to the same audience.

The mechanism is not contested by anyone, including many practitioners. A random distribution of dark particles on a pale surface gives the visual system exactly the conditions in which it produces recognisable forms, and different readers see different things in the same cup. The strength of the practice lies in what happens next: the reader speaks, the sitter responds, and the reading is built between them.

It is the most domestic of the divinatory arts in this atlas, requiring no equipment beyond the cup already in hand.
