Berytus's law school was widely known; two of Rome's most famous jurists, Papinian and Ulpian, were natives of Phoenicia and taught there under the Severan emperors. When Justinian assembled his ''Pandects'' in the 6th century, a large part of the corpus of laws was derived from these two jurists, and in AD533 Justinian recognised the school as one of the three official law schools of the empire.
