Vesica piscis, which translates to "fish bladder" in Latin, is a term used in mathematics and symbolism to describe an oval shape formed by the intersection of two circles. This shape is also known as the "mandorla" in Italian, meaning almond. In Christian art, the vesica piscis is used to depict the halo surrounding the figures of Jesus and the saints. It is also commonly referred to as the "lens" or the "lunate" shape. Regardless of the name, the vesica piscis remains a powerful symbol representing the intersection of two forces, the spiritual and physical realms, and the unity of opposites.
