Stentor

Stentor, a Grecian warrior in the army against Troy, whose voice was louder than the combined voices of fifty other men. His name has accordingly furnished an adjective which, in common use, describes a voice of unusual volume. It is said that Juno assumed the form of Stentor in order to encourage the disheartened Greeks (Iliad, 5, 785 sq.; Juven. Sat. 13, 112).
