Stone Guardians [Common Meter]

A stone dog guards the temple gate
with dead, but bulging, eyes.
And gargoyles mount a stern defense
from the cathedral spires.

But what's a mounted mask to do
to keep evil at bay?
And what's the flash of fu dog teeth
to end a vicious fray?

And what would lead me to assume
that evil lies outside,
when your greeter is pure ugliness
with wild and crazy eyes?
