An ‘Impresa’ was a two part symbol used on coins that incorporated a ‘figure’ and a corresponding motto; in this case, the ‘tizzone ardente coi secchi’, ‘burning embers with buckets’ in Corsican, act as the figure or physical symbol, with a motto “Humentia siccis” in Latin, which means ‘moist things to dry’, likely of French origin (?).
