TRIADS
The Irish have an old tradition of describing the attributes of something in lists of threes called "triads."

translated from 9th century Irish poetry

*Three accomplishments well regarded in Ireland:
A clever verse, music on the harp,
the art of shaving faces.

*Three qualities in narration:
a good flow, depth of thought, conciseness.

*Three things that are always ready in a decent
man's house: beer, a bath, a good fire.

from Gabriel Osborne, age 11

*The Three Qualities of Balance:
Love, Power, Wisdom
