The Proculeian or Pegasian school was one of the two most important schools of law in ancient Rome during the 1st and 2nd centuries.
The Proculeians originally took their name from the prominent jurist Proculus, but later came to often be called "Pegasians" after the prominent Proculeian Plotius Pegasus. However, the tradition on which the school was based comes from the jurist Marcus Antistius Labeo. Labeo spent half the year convening sessions at actual schools with regular students, who then carried forth his views and perspectives on the law. [1]
They were often contrasted with the Sabinian school, a rival school operating in roughly the same time and place, and were (very generally) considered the more progressive of the two, while the Sabinians were seen as more advocates of legal conservatism. Proculeians were thought to "push a legal principle to all its logical consequences," [2] and the legal tradition they inherited from Labeo was one of liberalism influenced by a keen understanding of the science of the day. [1] The Proculeians tried to enlarge the scope of Roman law, and tried to push legal innovations into practice such as were suggested by their liberal philosophy and the principles of reason. [3]
The progressive and conservative natures of the schools increased over time, and there came to be wider chasms between the two, which is perhaps why the schools came to be named after later prominent disciples and students, and not after their originators (the Proculeian school being named after Proculus but originated by Labeo, and the Sabinian school being named after Masurius Sabinus but originated by Gaius Ateius Capito).
The Roman legal compendium known as Digest records many decisions in which the Proculeians advocated. Among these were:
The rivalry with the Sabinians ended in the 2nd century CE when the two schools either merged or disappeared, or were united under the 3rd century's leading legal mind, Papinian. [1]
Tribonian was a notable Byzantine jurist and advisor, who during the reign of the Emperor Justinian I, supervised the revision of the legal code of the Byzantine Empire. He has been described as one of the wisest collaborators of Emperor Justinian.
Gaius Trebatius Testa was a jurist of ancient Rome, whose family, and himself, originated from Elea.
Marcus Antistius Labeo was a Roman jurist.
Gaius was a Roman jurist. Scholars know very little of his personal life. It is impossible to discover even his full name, Gaius or Caius being merely his personal name (praenomen). As with his name it is difficult to ascertain the span of his life, but it is safe to assume he lived from AD 110 to at least AD 179, since he wrote on legislation passed within that time.
Masurius Sabinus, also Massurius, was a Roman jurist who lived in the time of Tiberius. Unlike most jurists of the time, he was not of senatorial rank and was admitted to the equestrian order only rather late in life, by virtue of his exceptional ability and imperial patronage. Masurius was the first person to give "state-certified opinions" (publice respondere), a privilege granted by the emperor which marked increasing imperial control over the judicial process after the end of the Roman Republic. Before the Principate of Augustus, the value of legal opinions was based on the expertise of those who gave them. The passage in the Digest of Justinian that discusses the granting of Masurius's authority is thus a pivotal point in the history of Roman law.
Julius Paulus, often simply referred to as Paul in English, was one of the most influential and distinguished Roman jurists. He was also a praetorian prefect under the Roman Emperor Alexander Severus.
Lucius Octavius Cornelius Publius Salvius Iulianus Aemilianus, generally referred to as Salvius Julianus, or Julian the Jurist, or simply Julianus, was a well known and respected jurist, public official, and politician who served in the Roman imperial state. Of north African origin, he was active during the long reigns of the emperors Hadrian, Antoninus Pius, and Marcus Aurelius, as well as the shorter reign of Marcus Aurelius' first co-Emperor, Lucius Verus.
Pacuvius Labeo was a Roman jurist and senator, and one of the murderers of Julius Caesar. He was father of the more eminent jurist Marcus Antistius Labeo, who lived under the emperor Augustus.
Gaius Ateius Capito was a Roman jurist in the time of emperors Augustus and Tiberius. He was consul suffectus in the year 5 from July to December as the colleague of Gaius Vibius Postumus.
Aulus Ofilius was a Roman jurist of Equestrian rank, who lived in the Roman Republic. He is named as a jurist by Pomponius. Ofilius was a friend to Roman statesman Marcus Tullius Cicero, dictator Gaius Julius Caesar and in opinion had opposed the jurist Trebatius Testa.
The gens Antistia, sometimes written Antestia on coins, was a plebeian family at ancient Rome. The first of the gens to achieve prominence was Sextus Antistius, tribune of the plebs in 422 BC.
The gens Cocceia was a plebeian family at ancient Rome. The gens is first mentioned towards the latter end of the Republic, and is best known as the family to which the emperor Nerva belonged.
Proculus was an ancient Roman jurist who founded a distinctive tradition of the interpretation of Roman law. His followers were known as the "Proculiani", or Proculeans, after him.
The gens Neratia or Naeratia was a plebeian family at ancient Rome, some of whom subsequently became patricians. The first of the gens to appear in history occur in the time of Augustus, but they did not rise to prominence until the time of Vespasian, when Marcus Neratius Pansa became the first to obtain the consulship. The Neratii married into the Roman imperial family in the fourth century.
The gens Plautia, sometimes written Plotia, was a plebeian family at ancient Rome. Members of this gens first appear in history in the middle of the fourth century BC, when Gaius Plautius Proculus obtained the consulship soon after that magistracy was opened to the plebeian order by the lex Licinia Sextia. Little is heard of the Plautii from the period of the Samnite Wars down to the late second century BC, but from then to imperial times they regularly held the consulship and other offices of importance. In the first century AD, the emperor Claudius, whose first wife was a member of this family, granted patrician status to one branch of the Plautii.
(Lucius?) Plotius Pegasus was a Roman senator and jurisconsult active under the Flavian dynasty. He was suffect consul in an uncertain year, most likely 72 or 73, as the colleague of Lucius Cornelius Pusio Annius Messalla. Shortly after his ascension to the imperial throne, Domitian appointed Pegasus urban prefect, one of the most prestigious offices in a senatorial career.
Titius Aristo was a distinguished jurist of ancient Rome, who lived around the 1st and 2nd centuries CE, under the emperor Trajan, and was a friend of Pliny the Younger. He is spoken of by Pliny in terms of the highest praise, as not only an excellent man and profound scholar, but a lawyer thoroughly acquainted with private and public law, and perfectly skilled in the practice of his profession.
The gens Trebatia was a minor plebeian family at ancient Rome. Members of this gens are first mentioned at the time of the Social War, in which one of the Samnite generals was a Trebatius, but the best-known of the Trebatii is likely the jurist Gaius Trebatius Testa, a contemporary and friend of Cicero, Caesar, and Augustus.
