- : a geometrical figure having three points, especially one formed of three intersecting ellipses: The triquetra was often used in ancient art to symbolize a triune deity.

But the emblem, as the famous Triquetra, is one of the most ancient and celebrated of antiquity.
An interesting example of the transformation of a symbol into an emblem is found in the case of the triskele or triquetra.
