Everything about Flavius Vegetius Renatus totally explained
Publius Flavius Vegetius Renatus was a writer of the
Later Roman Empire. Nothing is known of his life or station beyond what he tells us in his two surviving works:
Epitoma rei militaris (also referred to as
De Re Militari), and the lesser-known
Digesta Artis Mulomedicinae, a guide to
veterinary medicine.
The latest event alluded to in his
Epitoma rei militaris is the death of the Emperor
Gratian (
383); the earliest attestation of this work is a
subscriptio by one Flavius Eutropius, writing in Constantinople in the year 450, which appears in one of two families of manuscripts, suggesting that a bifurcation of the manuscript tradition had already occurred. Despite Eutropius' location in Constantinople, the scholarly consensus is that Vegetius wrote in the Western Empire. Vegetius dedicates his work to the reigning emperor, who is identified as Theodosius,
ad Theodosium imperatorem, in the manuscript family that wasn't edited in 450; the identity is disputed: some scholars identify him with
Theodosius the Great, while others follow
Otto Seeck and identify him with the later
Valentinian III, dating the work 430-35.
Epitoma rei militaris
As G. R. Watson observes, Vegetius'
Epitoma "is the only ancient manual of Roman military institutions to have survived intact." Despite this, Watson is dubious of its value, for he "was neither a historian nor a soldier: his work is a compilation carelessly constructed from material of all ages, a congeries of inconsistencies." These antiquarian sources, according to his own statement, were
Cato the Elder,
Cornelius Celsus,
Frontinus,
Paternus and the imperial constitutions of
Augustus,
Trajan, and
Hadrian (1.8).
The first book is a plea for army reform; it vividly portrays the military decadence of the Late Roman Empire. Vegetius also describes in detail the organisation training and equipment of the army of the early Empire. The third contains a series of military maxims, which were (rightly enough, considering the similarity in the military conditions of the two ages) the foundation of military learning for every European commander from
William the Silent to
Frederick the Great. When the
French Revolution and the "nation in arms" came into history, we hear little more of Vegetius. Some of the maxims may be mentioned here as illustrating the principles of a war for limited political objectives with which he deals:
- "All that's advantageous to the enemy is disadvantageous to you, and all that's useful to you, damages the enemy"
- "the main and principal point in war is to secure plenty of provisions for oneself and to destroy the enemy by famine. Famine is more terrible than the sword."
- "No man is to be employed in the field who isn't trained and tested in discipline"
- "It is better to beat the enemy through want, surprises, and care for difficult places (for example, through manoeuvre) than by a battle in the open field"
- "Let him who desires peace prepare for war."
These are maxims that have guided the leaders of professional armies for most of recorded history, as witness the Chinese generals
Sun Tzu and
Wu. His "seven normal dispositions for battle," once in honor among European students of the art of war, are equally useful if applied to more modern conditions. His book on siegecraft is important as containing the best description of Late Empire and
Medieval siegecraft. From it, among other things, we learn details of the siege engine called the
onager, which afterwards played a great part in sieges, until the development of modern cannonry. The fifth book is an account of the materiel and personnel of the Roman navy.
The author of the 1911
Encyclopaedia Britannica article states that "In manuscript, Vegetius's work had a great vogue from its first advent. Its rules of siegecraft were much studied in the
Middle Ages." N.P. Milner observes that it was "one of the most popular Latin technical works from Antiquity, rivalling
the elder Pliny's
Natural History in the number of surviving copies dating from before AD 1300." It was translated into English, French (by
Jean de Meun and others), Italian (by the Florentine judge and others), Catalan, Spanish, Czech, and Yiddish before the invention of printing. The first printed editions are ascribed to Utrecht (1473), Cologne (1476), Paris (1478), Rome (in
Veteres de re mil. scriptores, 1487), and Pisa (1488). A German translation by Ludwig Hohenwang appeared at Ulm in 1475.
However, from that point Vegetius's position as the premier military authority began to decline, as ancient historians such as
Polybius became available.
Niccolò Machiavelli attempted to address Vegetius's defects in his
L'arte della Guerra (Florence, 1521), with heavy use of Polybius, Frontinus and Livy, but
Justus Lipsius's accusation that he confused the institutions of diverse periods of the Roman Empire and
G. Stewechius' opinion that the survival of Vegetius' work led to the loss of his named sources were more typical of the late Renaissance. While as late as the
18th century we find so eminent a soldier as
Marshal Puysegur basing his own works on this acknowledged model, and the famous
Prince de Ligne wrote "
C'est un livre d'or". In Milner's words, Vegetius' work suffered "a long period of deepening neglect".
The most reliable modern edition is that of Michael D. Reeve (Oxford, 2004). An early English version (via French) was published by
Caxton in 1489. For a detailed critical estimate of Vegetius's works and influence, see Max Jahns,
Geschiche der Kriegswissenschaften, i. 109-125.
Vegetius is keen to stress the shortcomings of the Roman Army in his lifetime. In order to do this he eulogises the Army of the early Empire. In particular he stresses the high standard of the recruits and the excellence of the training and the officer corps. In reality, Vegetius probably describes an ideal rather than the reality. The Army of the early Empire was a formidable fighting force but it probably wasn't in its entirety quite as good as Vegetius describes. In particular, the five foot eight minimum height limit would have excluded the vast majority of the working classes in Roman times.
Digesta Artis Mulomedicinae
N.P. Milner notes, "that it was the same Vegetius who wrote both works was proved through close verbal and stylistic parallels by C. Schoener, and is generally accepted."
