Clean lines pointing only forward.
History, with its hard spine & dog-eared

Having outlived every threat, will gratify
Only the mind, which is where it will exist.

Before mirrors studded with golden bulbs.
The oldest among us will recognize that glow—
But the word sun will have been re-assigned
To the Standard Uranium-Neutralizing device
