Marcus' son Commodus succumbed to the lures of self-indulgence, easy populism and rule by favourites. He described his reign as a "golden age", and himself as a new Romulus and "re-founder" of Rome, but was deeply antagonistic toward the Senate – he reversed the standard "Republican" imperial formula to "populus senatusque romanus" (the people and senate of Rome). He increasingly identified himself with the demigod Hercules in statuary, temples and in the arena, where he liked to entertain as a "bestiarius" in the morning and a gladiator in the afternoon. In the last year of his life he was voted the official title "Romanus Hercules"; the state cult to Hercules acknowledged him as heroic, a divinity or semi-divinity (but not a "divus") who had once been mortal. Commodus may have intended declaring himself as a living god some time before his murder on the last day of 192 AD.
