Erika Langmuir examines the presence and surprisingly complicated history of angels in Christian art. She points out that angels need not be winged; they can wear antique dress, contemporary church vestments, secular fashions, armor, or nothing at all; their gender and age are uncertain; they may not even have bodies but appear only as winged heads; and they are not always good (Satan, of course, is a fallen angel). Langmuir explores these intriguing characteristics of angels by looking at some of the best-known and most engaging religious paintings in the Western tradition.
