アレクサンデル・セウェルス
After the death of Alexander Severus and the usurpation of Maximinus Thrax, a unit of archers from Osrhoene in Mesopotamia, proclaimed Quartinus, a former provincial governor and friend of emperor Alexander Severus, purportedly against his own will. Those archers were led by Macedo and claimed to want revenge for Alexander's death. Quartinus himself was dismissed from the army by Maximinus after Alexander's death.
