Names of the 3 wise Monkeys and an additional 4th wise Monkey.

The Three Wise Monkeys sometimes called the Three Mystic Apes are a pictorial maxim and together they embody the proverbial principle to "see no evil, hear no evil, speak no evil".The names of the 3 wise monkeys are Mizaru, covering his eyes, who sees no evil; Kikazaru, covering his ears, who hears no evil; and Iwazaru, covering his mouth, who speaks no evil. Sometimes there is a 4th monkey depicted with the others,Shizaru with crossed arms symbolizing the principle of "do no evil".
In English, the monkeys' names are often given as Mizaru, Mikazaru,and Mazaru,but the last two names were corrupted from the Japanese originals.
