Quintinus was a Roman general who was active in the 4th century during the reign of emperor Theodosius (378-395). As master of soldiers of the usurpator Magnus Maximus (383-388) he led an expedition on the Rhine against the Franks of Marcomer in 388. He asked for help from General Nannienus, [1] who, however, refused. Quintinus was lured into an ambush and defeated. [2]
