Vesica piscis arch

Two circles of the same size
overlap by their radius
forming a shape like your eyes
known as a vesica piscis.

Half of these almond-shaped things
creates a gothic motif
whose curved elegance brings
masonry stress some relief.

Less mass than a barrel vault
thinner walls support it
closer to a catenary, called
a “fishes bladder” distorted.
