The Digest, also known as the Pandects (Latin: Digesta seu Pandectae, adapted from Ancient Greek πανδέκτης pandektes, "all-containing"), is a name given to a compendium or digest of Roman law compiled by order of the emperor Justinian I in the 6th century (AD 530-533). It spans 50 volumes, and represented a reduction and codification of all Roman laws up to that time.The Digest was part of the Corpus Juris Civilis, the body of civil law issued under Justinian I. The other two parts were Institutes of Justinian, and the Codex Justinianus. A fourth part, the Novels (or Novellae Constitutiones), was added later.
