The Celtic symbol for Triad / Trinity / Triquetra had a plethora of symbolic meanings. To the ancients, this shape was thought to signify everything from Spirit, Mind, and Body; to Mother, Father, Child. Typically seen with the addition of a circle around the three points to signify unity of the three concepts, Celtic meanings behind this symbol run deep, and can come to represent any three-pronged personifications you see fit. I chose to eliminate the circle enclosure here to draw more attention to the Triad's own aesthetic symmetry.
