A discussion of a geometric shape that became a symbol known as mandorla or vesica piscis, starting from a Pythagorean point of view [PDF]

open access: yes, 2020
Here we propose a discussion about the "mandorla" or "vesica piscis". It is a type of 2-dimensional lens, that is, a geometric shape formed by the intersection of two circles with the same radius, intersecting in such a way that the centre of each circle
