Res Gestae

And when the emperor was seen on the high tribunal and was already preparing to deliver a most mild address, intending to speak to them as future obedient subjects, one of their number, struck with savage madness, hurling his shoe at the tribunal, shouted Marha, marha (which is their warcry), and the rude crowd following him suddenly raised a barbarian banner and with savage howls rushed upon the emperor himself.
