According to Diodorus Siculus, recounting the story in "Bibliotheca historica", Perilaus (or Perillus) of Athens invented and proposed it to Phalaris, the tyrant of Akragas, Sicily, as a new means of executing criminals.

Instead, Phalaris, who was disgusted by these words, ordered its horn sound system to be  tested by Perilaus himself, tricking him into getting in the bull. When Perilaus entered, he was immediately locked in and the fire was set, so that Phalaris could hear the sound of his screams. Before Perilaus could die, Phalaris opened the door and took him away.
