A well-to-do bourgeois, Tartarin lives in Tarascon, a small southern town, among friends who, like him, love hunting "à la casquette", gossip, aperitifs and thought-provoking journeys. Imaginative like all his compatriots, Tartarin ended up believing he had once been to Shanghai, so fervently did he recount his illusory adventures. It was even rumored that Tartarin was about to leave for Africa to hunt wild beasts, and this was so insistent that the brave man, urged on by his friends, was forced "for the sake of honor" to embark.
