Tears of Saint Peter

“In Peter’s heart, as daylight at length came,

The anguish grew, and he flushed deep for shame,

Though no man was there to behold him sin,

For now he recognized his own offence.

A noble heart no witness ever needs

To shame him, but is cowed by his own deeds,

Though only Heaven and earth watch in silence.”
