Ali Baba

a'le ba'ba, the central character in the famous Arabian tale of The Forty Thieves. He overhears the robbers' password of "Open Sesame," and uses it in their absence to enter their famous cave and despoil it of treasure. Having found who took their treasure, the robbers vowed vengeance, and had themselves conveyed in empty covered jars and set down in Ali Baba's court; but his faithful slave, Morgiana, overheard their conversation and killed them, one and all, by pouring hot oil into the jars in which they were concealed.
