Triple deity

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.

In religious iconography or mythological art, three separate beings may represent either a triad who always appear as a group (Greek Moirai, Charites, Erinyes; Norse Norns; or the Irish Morrígna) or a single deity known from literary sources as having three aspects (Greek Hecate, Diana Nemorensis). In the case of the Irish Brigid it can be ambiguous whether she is a single goddess or three sisters, all named Brigid.The Morrígan also appears sometimes as one being, and at other times as three sisters, as do the three Irish goddesses of sovereignty, Ériu, Fódla and Banba.

The Matres or Matronae are usually represented as a group of three but sometimes with as many as 27 (3 × 3 × 3) inscriptions. They were associated with motherhood and fertility. Inscriptions to these deities have been found in Gaul, Spain, Italy, the Rhineland and Britain, as their worship was carried by Roman soldiery dating from the mid 1st century to the 3rd century AD.Miranda Green observes that "triplism" reflects a way of "expressing the divine rather than presentation of specific god-types. or beings are ubiquitous in the Welsh and Irish mythic imagery" (she gives examples including the Irish battle-furies, Macha, and Brigit). "The religious iconographic repertoire of Gaul and Britain during the Roman period includes a wide range of triple forms: the most common triadic depiction is that of the triple mother goddess" (she lists numerous examples).
