The Digest (Latin: Digesta), also known as the Pandects (Pandectae; Ancient Greek: Πανδέκται, Pandéktai, "All-Containing"), was a compendium or digest of juristic writings on Roman law compiled by order of the Byzantine emperor Justinian I in 530–533 AD. It is divided into 50 books.
The Digest was part of a reduction and codification of all Roman laws up to that time, which later came to be known as the Corpus Juris Civilis (lit. 'Body of Civil Law'[1]). The other two parts were a collection of statutes, the Codex (Code), which survives in a second edition, and an introductory textbook, the Institutes; all three parts were given force of law. The set was intended to be complete, but Justinian passed further legislation, which was later collected separately as the Novellae Constitutiones (New Laws or, conventionally, the "Novels").
