Era notations test page

In post-Severan times (after 235 AD), the small number of pagan senators interested in becoming pontiffs led to a change in the pattern of office holding. In Republican and Imperial times no more than one family member of a gens was member of the College of Pontiffs, nor did one person hold more than one priesthood in this collegium. However, these rules were loosened in the later part of the 3rd century A.D. In periods of joint rule, at first only one of the emperors bore this title, as it occurred for the first time during the joint reign of Marcus Aurelius and Lucius Verus (161–169 AD), when only Marcus Aurelius was pontifex maximus, but later two pontifices maximi could serve together, as Pupienus and Balbinus did in 238 AD—a situation unthinkable in Republican times.
