According to Gabriel-Henri Blanc, who considered the History of the Provence's villages, Les Salles' inhabitants (called "lei Salen" in the old Provence's language) received the nickname "flat-snails-eaters" ("lei manjo-platello").

Later on, Les Salles' inhabitants were called "lei neblats" ("foggies"... not "froggies" !) because of the fog which occupied the bottom of the valley around the Verdon river.
