Libri juris civilis

The Libri juris civilis was a significant legal work by the Roman jurist Gaius Cassius Longinus, who flourished in the 1st century AD. He was a student of the renowned jurist Massurius Sabinus and co-founded a legal school. Cassius held several important public offices, including consul and proconsul, and was later banished by Emperor Nero before being recalled by Emperor Vespasian.1

His Libri juris civilis, a work comprising 10 books, contained extracts that were later incorporated into the Corpus juris civilis by the Byzantine emperor Justinian I in the 6th century. Roman law, as developed by jurists like Cassius, has profoundly influenced legal systems worldwide, forming the basis for the civil law tradition found in many European countries and beyond.123
