The name of Harlequin derives from Old French Hellequin, leader of la maisnie Hellequin, thought to be related to the Old English Herla, a character often identified with Woden.
Italian Arlecchino by folk etymology was associated with Latin Herculinus, "little Hercules".
The notion that the Harlequin motif grew out of France is evidenced by Hellequin, a stock character in French passion plays. Hellequin, a black-faced emissary of the devil, is said to have roamed the countryside with a group of demons chasing the damned souls of evil people to Hell.
The physical appearance of Hellequin offers an explanation for the traditional colours of Harlequin's mask (red and black). [text -wikipedia; image left by Cezanne ; image above by Giovanni di Paolo - wikicommons]
The complete fool is half prophet.
A fool can ask more questions in an hour than a wise man can answer in a year.
A dead man is mourned seven days; a fool, his lifetime.
A fool is his own informer.
A fool shows his annoyance at once, but a prudent man overlooks an insult.
A fool who can keep silent is counted among the wise.
