The peacock is a symbol frequently found in early Christian Celtic art. According to an ancient belief, the flesh of the peacock does not putrefy. In fact, St. Augustine of Hippo put this belief to the test when he ordered some of his roast peacock dinner to be put aside. After 30 days he found that there was no bad smell and after one year the flesh had become only a little desiccated. As a result the peacock became the symbol of the incorruptibility of Christ.
