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.

The biggest arch ever

St. Louis’ arch is quite airy
although it’s not masonary
at the top it’s kinda scary
but you needn’t be too wary
because it is a catenary.

Compassion for a rock

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 planet
we just take them for granite.

The masonry of crystals

It’s more covalent,
less ionic
with rows prevalent
on atomic
scale of being and
such small seeing.

Less ambivalent
more ironic
when stacking meant
the sardonic
scale of bricks and
atoms’ tricks.

Watch iron rust
and see wood rot
but brick you trust
that it will not.

Parge coat

To make masonry walls like alabaster
It takes some fussing and some doting
Using a trowel, and mortar or plaster
Squeeze and press that parge coating.

If a masonry dome is placed on top
of a square or hexagonal or octagonal room
the dome and the room will fit lop
sided, not at  all, not now, not any time soon.

But by making the dome and the room both fit
and being creative and inventive
the mason contrives a dome that will sit
upon a contrivance called a pedentive.
