The triquetra at the foot of the shield is older than the other two emblems by several centuries. It appears on the Funbo Runestone in Sweden, in the marginalia of the Book of Kells around 800, and in the carved stone crosses of Iona and Lindisfarne. Originally a Celtic and Norse design motif from roughly 400 to 700, it was absorbed by Insular Christian art as a symbol of the Trinity — three persons, one substance, one unbroken loop. The geometry made the argument for perseverance: an endless line, three arcs returning to themselves with no beginning or end. Renaissance emblem books captioned interlaced devices of this kind nunquam frangitur, meaning never broken. When the heraldic tradition needed a symbol for the active form of constancy, the triquetra was already waiting, eight centuries old, ready for the work.
The phrase came together slowly. Fiducia entered Latin in the first century B.C. as a Roman legal term — a trust in property held by one party for the benefit of another. By the time Augustine of Hippo wrote in the early fifth century, the word had migrated from contract law to the disposition of the soul, meaning the trust a man places in God, in his lord, and in the bonds he has sworn. Perseverantia took longer. Augustine rehabilitated it as a virtue in his last works, arguing it was a continuing grace rather than mere stubbornness. Temperantia was the oldest as a named virtue, descending from Plato and Aristotle through Cicero into the Christian moral vocabulary, where Aquinas placed it among the four cardinal pillars of a just life.
Why the Three Together
Two virtues can be balanced; three must be ordered. The order tells you what the bearer believes about how a soul is built. This shield believes the soul is built from the ground up — trust first because nothing is built without it, perseverance second because trust without persistence is a flicker, and temperance last because the other two need a governor or they consume themselves. It is not the order of the schoolroom. It is the order of the road, the order a man arrives at after he has been knocked off a horse a few times and chosen to remount.
