De rebus bellicis


De rebus bellicis is an anonymous work of the 4th or 5th century which suggests remedies for the military and financial problems in the Roman Empire, including a number of fanciful war machines. It was written after the death of Constantine I in 337 and before the fall of the Western Roman Empire in 476. Some researchers suggest that it may refer to the Battle of Adrianople of 378, or even the death of Emperor Theodosius I in 395, as 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.
