“Between 1500 and 1533, the great humanist Erasmus compiled his Adagia, a collection of some 4,251 classical proverbs and commonplaces with a rich scholarly commentary—a truly astonishing achievement. One of his most well-known adages was ‘Festina Lente’ or hasten slowly. Aldus adopted it for a slogan, its visual counterpart being an emblem of dolphin and anchor, which he used as a printer’s mark. Erasmus suggests a possible origin for the expression in a witty inversion of the Greek σπεύδε ταχέως, ‘hasten hastily’, found in Aristophanes’ The Knights. It is most famous as the official motto of the Roman emperors Augustus and Titus; Erasmus thus dubs it the ‘royal proverb’, and remarks that it advocates ‘a wise promptness together with moderation, tempered with both vigilance and gentleness, so that nothing is done rashly and then regretted, and nothing useful to the common weal omitted out of carelessness’. It represents, in short, the reining of passion by reason, Plato’s ideal of statecraft—it is the paragon of proverbs.”
