Manius Acilius Glabrio was a Roman Senator who served as consul ordinarius in AD 91 as the colleague of Trajan, afterwards emperor. Although one of many senators executed during the reign of Domitian on the alleged grounds of plotting against the emperor, he was remembered by his contemporaries best for his strength. Domitian summoned Glabrio during the latter's consulate to his Alban estate during the festival of the Juvenalia to kill a large lion; not only did Glabrio despatch the beast, but he escaped all injury. Following his defeat of the lion, Glabrio was banished by Domitian, then executed while in exile.
