For 10 points, name this Roman emperor who established the "tetrarchy," dividing the empire into four divisions.
This man was the inspiration for a mythical evildoer who once stole the Sun and tore off a piece of flesh from Saint John's foot. He secured power after his forces won the Battle of the Margus. On the day of the Feast of the Terminalia, this ruler ordered the burning of a location at Nicomedia, a decision many historians believe was influenced by Galerius. He retired to grow vegetables in his palace in modern-day Split, and may have killed himself after hearing of the failed coup of his old colleague Maximian. This ruler, the first leader of his empire to voluntarily abdicate, is the namesake of the bloodiest official persecution of Christianity within ancient Rome.
