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, calleda “fishes bladder” distorted.

We take rocks for granted
unearthing them when planted
they get in the way of growing roots
and stop the plant’s precious shoots
but when we use rock for buildings
we don’t need to really kill things
like trees for wood or wool for rugs
before they're killed they get hugs
but rocks and stones on this planetwe just take them for granite.
