The Monk Pardus the Hermit

from the Synaxarion:

The Monk Pardus the Hermit, a Roman, was involved in his youth with the teamster's craft. One time when he set off to Jericho, a boy accidentally fell under the legs of his camels. The camels trampled the boy to death. Shaken by this occurrence, Pardus took monastic vows, and withdrew to Mount Arion. Thinking himself under the condemnation of a murderer, and seeking a punishment of death, the Monk Pardus entered the cave-den of a lion. He poked the wild beast and prodded it with a spear so that the lion would rend him apart, but the creature would not touch the hermit. The Monk Pardus then took off his clothes and lay down upon the path that the lion would take for water. But even here, the lion merely leaped over the hermit. And the elder then perceived, that he had been forgiven by the Lord. Having returned to his mountain, the Monk Pardus dwelt there in fasting and prayer until the end of his days. He died in the 4th Century.
