Membership in the various colleges of priests, including the College of Pontiffs, was usually an honor offered to members of politically powerful or wealthy families. Membership was for life, except for the
Vestal Virgins whose term was 30 years. In the early Republic, only
patricians could become priests. However, the
Lex Ogulnia in 300 BC granted the right to become
pontifices and
augures to
plebeians. Nevertheless, even in the late Republic it was still believed that the auspices ultimately resided with patrician magistrates, and certain ancient priesthoods: the
Dialis,
Martialis and
Quirinalis flamines, and the college of the
Salii were never opened to the plebeians. The number of members in the College of Pontiffs grew over time. Originally consisting of three members, the number was increased to nine by the third century BC;
Sulla increased the number to fifteen; Augustus increased the number even further, perhaps to as many as twenty-five. depicting
Julius Caesar as
pontifex maximus Until the 3rd century BC, the College elected the
pontifex maximus from their own number. The right of the college to elect their own
pontifex maximus was returned, but the circumstances surrounding this are unclear. This changed again after Sulla, when in response to his reforms, the election of the
pontifex maximus was once again placed in the hands of an assembly of seventeen of the twenty-five
tribes. However, the College still controlled which candidates the assembly voted on. During the Empire, the office was publicly elected from the candidates of existing pontiffs, until the Emperors began to automatically assume the title, following
Julius Caesar’s example. The
pontifex maximus was a powerful political position to hold and the candidates for office were often very active political members of the College. Many, such as Julius Caesar, went on to hold
consulships during their time as
pontifex maximus. However, after 44 BC the pontiffs, as with the other official priests of Rome, lost their political influence. Martha Hoffman Lewis could only find four instances where the pontiff's advice was asked: before Augustus' marriage to Livia; in 37 BC when they ordered the removal of the body of one of the proscribed from the Campus; they made expiatory sacrifices on the day the emperor Claudius married Agrippina; and their advice was sought concerning reforms of the discipline of the
haruspices. ==Role in the Roman State==
