Cosimo I de' Medici, Grand Duke of Tuscany
Certain gold coins minted for Augustus bore images of a crab and a butterfly to attempt an emblem for the adage. Other such visualizations include a hare in a snail shell; a chameleon with a fish; a diamond ring entwined with foliage; and perhaps most recognizably, a dolphin entwined around an anchor. Cosimo I de' Medici, Grand Duke of Tuscany took "festina lente" as his motto and illustrated it with a sail-backed tortoise.
