Sesame.—In Arabian tales given as the talismanic word which would open or shut the door leading into the cave of the forty thieves. In order to open it, the words to be uttered were, “Open, Sesame!” and in order to close it, “Shut, Sesame!” Sesame is a plant yielding grain which is sometimes used for food, and from which an oil is expressed. When Cassim forgot the word, he substituted “Barley,” but without effect. Sesame has come into general use in connection with any word or act which will open the way for accomplishment of the thing desired.
