Here is an interesting message I received about Plato’s “Ring of Gyges” myth:

…I have found what I think might be a reference to the Brazen Bull method of torture and execution. Refer to the text at Stephanus number 359 D on page 55. It is the story of Gyges and the ring as told through Plato. In this translation as he descends into the chasm he then finds “a hollow bronze horse fitted with doors.”, could this in any way be a reference to the Brazen Bull. As he does find a corpse with no clothing, only equipped with the ring…

Dear Cory, in the original the word is “horse”, not “bull”, and is thus correctly translated in the Jowett edition (see Plato, Republic 1, p. 41) and in the translation you quote. No one has connected the reference with the brazen bull torture, and there are more things one must observe.
