In Greek mythology, Stentor (Ancient Greek: Στέντωρ; gen.: Στέντορος) was a herald of the Greek forces during the Trojan War.
Stentor is mentioned briefly in Homer's Iliad in which Hera in the guise of Stentor, whose "voice was as powerful as fifty voices of other men"[1] encourages the Greeks to fight.
Stentor's story is the origin of the term "stentorian", meaning loud-voiced, for which he was famous. Aristotle uses the concept in his Politics Book 7, Chapter IV saying, "For who can be the general of such a vast multitude, or who the herald, unless he have the voice of a Stentor?"
