From the greatest to the least.
The best remedy for anger is delay. -Seneca
The chief or senior priest and head of the state religion of Rome; in this case, it is not a reference to the Roman Catholic Church but to classical Rome.
At first he was probably required to be a patrician, but by the middle Republic era he was more than likely to be a plebeian. He supervised all of the various members of the priestly colleges—augurs, pontifices, other minor priests, and the Vestal Virgins.
