Winged messengers have mesmerized humans since the dawn of civilization. They have been immortalized in art, trivialized as decorative accessories, and dismissed by science - yet the simplest question remains obscure: what is an angel?

Much of what we think we know about angels is at odds with their long and curious history. Hebraic, Christian, and Muslim scripture all describe angels and demons, yet each offer slightly different versions. In search of a definitive portrait, Angels: Good Or Evil? traces the history of these winged beings, exploring their lineage from the ancient Egyptians and the Greco-Romans to today. Listen to firsthand accounts of those who claim to have encountered angels and hear experts grapple with their mysterious legacies.

From believers to skeptics, priests to scientists, The History Channel offers all sides of the debate surrounding these mythical, mystical, ethereal entities.
