Charletan, signifies an empiric or quack, who retails his medicines on a public stage, and draws people about him with his buffooneries, feats of activity, &c. The word, according to Calepine, comes from the Italian ceretano; of Ceretum, a town near Spoletto in Italy, where these impostors are said to have first risen. Menage derives it from ciarlatano, and that from circulatorius or circulator, a quack.
