rex sacrōrum (‘king of the sacred things’), at Rome after the expulsion of the kings (510 BC), a priest whose duty it was to perform some of the king's religious functions. He was a patrician, appointed for life, and unlike the pontifex maximus (to whom he was superior in rank and precedence though inferior in religious authority) disqualified from holding any other office. He and his wife (rēgīna, ‘queen’, who had some religious duties) performed certain state sacrifices.
