vesica piscis. 1. Glory,
mandala, or
mandorla of the upright almond-shaped type produced by the geometrical process of placing two equilateral triangles above and below a baseline as mirror-images and striking arcs from each end of the base-line passing through the other points of the triangle. This creates two pointed arches base-to-base, commonly found as a vertical
aureole enclosing of figure of e.g. Christ in Majesty. Its resemblance to a fish, or to a fish's bladder, relates it to the
Chrismon. The shape is also found in windows, e.g. the
rose-window in the south
transept of Lincoln Cathedral.
2. Light in
Second Pointed Curvilinear or Flowing
tracery resembling a tadpole or the air-bladder of a fish.
