  by his fellow Greeks for renouncing his alliance with Perseus of
  Macedon against Rome and appearing before the Senate in 167/6 dressed
  as a Roman freedman, addressing his audience as‘saviour gods’. His
  later unsuccessful attempt to invade Pergamene territory ended in his
  being stoned to death by his own subjects. [NEW PARAGRAPH] The
  attributes and symbolism of Mercury on this coin must be seen as
  apotropaic, but in the end did not help this doomed and pathetic king.
