en.wikipedia.org
A triple deity (sometimes referred to as threefold, tripled, triplicate, tripartite, triune or triadic, or as a trinity) is three deities that are worshipped as one. Such deities are common throughout world mythology; the number three has a long history of mythical associations. Carl Jung considered the arrangement of deities into triplets an archetype in the history of religion.[1]
