De rebus bellicis is a 4th or 5th century anonymous work about war machines used by the Roman army of the time. It was written after the death of Constantine I (337; explicitly states that Constantine was dead when the work was written), and before the fall of the Western Roman Empire (476). Some researchers suggest that it may refer to the Battle of Adrianople (378; speaks about the serious threat posed by the barbarian tribes to the empire), or even the death of Emperor Theodosius I (395; in many cases it uses the plural form of the word "princeps", the title of the emperor, which may refer to the split of the Empire between Honorius and Arcadius after the death of Theodosius).
