Digest of Justinian

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 Eastern Roman (Byzantine) 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.

The original Codex Justinianus was promulgated in April of 529 by the C. "Summa". This made it the only source of imperial law, and repealed all earlier codifications. However, it permitted reference to ancient jurists whose writings had been regarded as authoritative. Under Theodosus II's Law of Citations, the writings of Papinian, Paulus, Ulpian, Modestinus, and Gaius were made the primary juristic authorities who could be cited in court. Others cited by them also could be referred to, but their views had to be "informed by a comparison of manuscripts."

The principal surviving manuscript is the Littera Florentina of the late sixth or early seventh century. In the Middle Ages, the Digest was divided into three parts, and most of the manuscripts contain only one of these parts. The entire Digest was translated into English in 1985.

The Digest was discovered in Amalfi in 1135, prompting a revival of learning of Roman law throughout Europe. Other sources claim it was discovered in 1070 and formed a major impetus for the founding of the first university in Europe, the University of Bologna (1088).
