I've seen a lot of sites place the origin of 'Put up your dukes' to come from put up your Duke of Yorks etc. However I'm currently writing a paper on an ancient Greek source, which involves Polydeukes, an unmatched boxer in ancient Greek times. Could it be possible that Dukes came from the "deukes" part of Polydeukes name. Polydeukes was also a son of Zeus and has been attributed to be one of the twins of Gemini.
