Enochian Chess is a four-handed variant played on an eight-by-eight board divided into four kingdoms, each corresponding to one of the classical elements and to one of the four Enochian Watchtowers of John Dee. It was developed in the late nineteenth century by William Wynn Westcott and S. L. MacGregor Mathers of the Hermetic Order of the Golden Dawn as a contemplative and divinatory practice: each piece took on an astrological and elemental meaning, and the unfolding of the game was read as a figure of the unfolding of a question. The Academy hosts it as a Heart-Opener because its practice is, in the end, a structured meditation on the symbols by which a tradition organised its hopes. To play it well is to feel one of the Renaissance hermetic syntheses from the inside; to play it at all is to encounter, by way of a board game, a great deal of inherited Western esoterica.
