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 order of the three words on the banner tells its own story. Read from the bottom up — Fiducia, Perseverantia, Temperantia — and you have the order of moral development as the late scholastics understood it. You begin in trust, in God or in lord or in the fellowship of arms. Trust held against time becomes perseverance. Perseverance refined by judgment becomes temperance, the governing virtue that keeps the other two from curdling into credulity and obstinacy. The crowning word sits on top because it is, in the medieval mind, the word that crowns the soul. There is a story, possibly apocryphal, that the English mercenary captain Sir John Hawkwood, who served Florence between roughly 1364 and his death in 1394, kept three words burned into the inside of his shield where only he could see them. The chronicler Filippo Villani recorded them around 1395 as fides, durare, modus — faith, endure, measure. Trust, hold, govern. The order finds its way to the men who need it.
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.
