"...And such a monument a man may make!
These things of steel and marble, words and clay,
pass down for generations; we mistake
a century as longer than a day.
The efforts of a man no more may last
than those put forth by his entire kind;
the shadow each new artifact may cast
extends no more beyond the species’ line.
Someday the contrails human steps have traced
will be, like every mortal feat, erased."
