Rhoemetalces, king of the Thracians, who had changed his alliance from Antony to Augustus, could not practise moderation when there was any drinking going on, and gave much offence by his disparaging remarks about his new alliance, whereat Augustus, as he drank to one of the other kings, said, ‘I like treachery, but I cannot say anything good of traitors.’ 1
