Vegetius

Publius (or Flavius) Vegetius Renatus, known as Vegetius (), was a writer of the Later Roman Empire (late 4th century). Nothing is known of his life or station beyond what is contained 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. He identifies himself in the opening of his work ''Epitoma rei militaris'' as a Christian. Provided by Wikipedia
