Mandorla [mænˈdɔːlə]. From Italian: lit. almond, and from Late Latin amandula. In the Medieval Age it was known as vescia piscis. The mandorla is an almond-shaped aureola found in the religious art and architecture of many world traditions. In Christian iconography the mandorla is commonly associated with Christ or with the Virgin Mother of God. It is found in Buddhism and Hinduism, whose traditions run parallel to, and predate, Christianity, and also later in the symbology of Free Masonry. The shape has its root in sacred geometry, as the width of the centre of its horizontal plane is equal to the radius of each of those overlapping circles whose spheres are produced both arcs, at once, extend outwardly and return in order to complete themselves, arcs whose imaginal bodies represent both emanation and convergence—a coming together, a growing and unity.
