a friend of the emperor Alexander Severus, who, after the murder of that prince, was dismissed from the camp by his successor, and having been encountered by some soldiers of Osrhoene deeply attached to the memory of their late sovereign, was forced by them to place himself at their head, and reluctantly assumed the purple. Soon after, while sleeping in his tent, he was assassinated by a certain Macedo, who had formerly commanded this body of foreign troops, and had been the chief instigator of the insurrection, but who now sought to ingratiate himself with Maximinus by presenting him with the head of his rival. He received the reward which he merited. Maximinus accepted the offering with joy, and then issued a command that the double traitor should himself be put to death, as the original author of the revolt. (Herodian. 8.3, 4.) This Quartinus seems to be the same person with the TYCUS mentioned by Capitolinus (Maxim. 100.11), and with the TITUS of Trebellius Pollio (Trig. Tyrann. xxxix.).
