A propos de l’auteur

Vegetius or Publius Vegetius Renatuswas a writer of the Later Roman Empire (late 4th century). There are little data about his life. All the information about him is drawn from 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. In one of the books, he identifies himself as a Christian.
