Part the fourth of many.
Today we have gyronny, much loved by those who want to be Norse-inspired in their heraldry – Norse round shields have been found with similar radial divisions on them. Gyronny arrondi (or arrondy, depending on how you Anglicize it) is the wavy-edged version.
And then there’s the Society-specific “gyronny arrondi of three”, the mega-swirly pair in the bottom row. That’s actually a Germanic field division called, in German, “Schneckendreipass”. Literally translated, that’s something like “snail trefoil”. Calling it “gyronny arrondi of three” is the SCA College of Arms’ attempt at keeping all our blazoning English-only, which is a laudable goal, but leads to weirdness like this. Actual “gyronny arrondi of three” would look more like per pall with a wavy division line, I think. Thankfully the awesome folks on the Facebook Baby Heralds of the SCA group got me sorted out on schneckendreipass and other amusements!
Favourites in this batch? Gyronny of any sort is always striking, and Cerdic Weyfare’s “Gyronny arrondy of six gules and argent” is classically simple and, being only six divisions, maybe a bit easier to read than some of the other gyronny variants. I’m also always a sucker for the heraldic fur variants, so Adelheld von Katzenellenbogen’s “Gyronny erminois and pean” appeals.
