In the Roman empire, a number of codifications were developed, such as the Twelve Tables of Roman law (first compiled in 450 BC) and the "Corpus Juris Civilis" of Justinian, also known as the Justinian Code (429 - 534 AD). However, these law codes did not exhaustively describe the Roman legal system. The Twelve Tables were limited in scope, and most legal doctrines were developed by the "pontifices", who "interpreted" the tables to deal with situations far beyond what is contained therein. The Justinian Code collected together existing legal material at the time.
