Was More Than One Dove

Thief of joy, brick of the walls
That were first built up in Ur,

Stick, switch, whip, and staff of life,
Pulse in wrists, catch in the throat,

Rod of one and none that rules
The world of names, games, and gasps,

God of thrones, mount of the gods,
Womb of math and charts of moons,

What this is since it is not
That, which means that is not this.
