The Corpus Agrimensorum Romanorum is a Roman book on land surveying which collects works by Siculus Flaccus, Frontinus, Agennius Urbicus, Hyginus Gromaticus and other writers. The text is preserved in the fifth or sixth-century uncial manuscript known as Codex Guelfferbytanus 36.23 Augusteus 2, held in the Herzog August Bibliothek in Wolfenbüttel. It is one of the few surviving non-literary and non-religious illuminated manuscripts from late antiquity. The text was first printed in 1554 by Adrianus Turnebus, under the title De Agrorum Conditionibus et Constitutionibus Limitum.
