Abbott Handerson Thayer is recognized today for his ethereal angels, portraits of woman and children, landscapes, and delicate flower paintings. Angel is both a portrait of his daughter Mary at age eleven and an allegory of hope and spirituality. Thayer manipulated the paint with brooms, scrapers, his fingers, and even a paint tube to achieve his effects. The Renaissance-inspired frame, called a tabernacle type, was designed specifically for this painting by American architect Stanford White.
