A triad, in a religious context, refers to a grouping of three gods, usually by importance or similar roles. A triad of gods were usually not considered to be one in the same being, or different aspects of a single deity as in a Trinity or Triple deity. Triads of three closely associated deities were commonly found throughout the ancient world, and in particular in the religious traditions of Ancient Greece and Egypt.
