mandorla, (Italian: “almond”), in religious art, almond-shaped aureole of light surrounding the entire figure of a holy person; it was used in Christian art usually for the figure of Christ and is also found in the art of Buddhism. Its origins are uncertain. The Western mandorla first appears in 5th-century mosaics decorating the Church of Santa Maria Maggiore in Rome, where it surrounds certain Old Testament figures.
By the 6th century the mandorla had become a standard attribute of Christ in scenes of the Transfiguration (in which Christ shows himself to his Apostles transformed into his celestial appearance) and the Ascension (in which the resurrected Christ ascends to heaven) and, later, in other scenes involving the resurrected or celestial Christ, the death of the Virgin (in which, having descended from heaven, Christ stands by the deathbed of his mother), the descent into limbo, the Last Judgment, and the nonhistorical theme of Christ in majesty. In the late Middle Ages the mandorla also occasionally enclosed the Virgin in scenes of the Last Judgment and of her Assumption into heaven, reflecting her increased popularity. In the 15th century, however, with the growth of naturalism in art, the mandorla became less popular, being incongruous in a naturalistic context, and it was abandoned by the painters of the Renaissance.
