Androcles and the Lion
.Androcles was a runaway slave who took refuge in a cavern. A lion entered, and instead of tearing him to pieces, lifted up his fore paw that Androcles might extract from it a thorn. The slave being subsequently captured, was doomed to fight with a lion in the Roman arena. It so happened that the same lion was let out against him, and, recognising his benefactor, showed towards him every demonstration of love and gratitude.
