According to Pliny's anecdote, Demetrius asked Protogenes to present himself at his headquarters, and when he did so he asked him how he could work away at his painting while the fate of the town hung in balance. The painter replied: 'I am aware that you are making war upon people and not the arts.' There's is just the faintest flavour of flattery about it; enough at any rate to win Demetrius, who assigned the painter a special bodyguard and ordered that he was not to be molested.
