Combined Triangle, Trinitarian, Dove Symbol - Many Trefoils

This trefoil shape also includes a descending dove; a reference to Christ's Baptism.

       Trefoil (from Latin trifolium, "three-leaved plant", French trèfle, Italian trifoglio, German Dreiblatt and Dreiblattbogen, Dutch klaver, "clover", same as clubs) is a graphic form composed of the outline of three overlapping rings used in architecture and Christian symbolism. The term is also applied to other symbols of three-fold shape.

       Trefoil is a term in Gothic architecture given to the ornamental
foliation or cusping introduced in the heads of window lights,  tracery,
 panellings, etc., in which the center takes the form of a three-lobed leaf
(formed from three partially overlapping circles). One of the earliest
examples is in the plate tracery at Winchester (1222–1235). The fourfold
 version of an architectural trefoil is a quatrefoil.

       A simple trefoil shape in itself can be symbolic of the Trinity,
 while a trefoil combined with an equilateral triangle was also
 a moderately common symbol of the Christian Trinity
during the late Middle Ages in some parts of Europe.
