At the head of the diaconate was the archdeacon; the bishop's main deputy in managerial affairs. Originally inferior in rank to the archpriest, the archdeacon by the sixth century had established clear pre-eminence. Subdeacons assisted the deacons, but unlike them were allowed to marry after ordination; consequently many clerics stopped the cursus honorum at this point, and it was not unusual for a subdeacon to be elected bishop; and even Pope.
