Pope Agapetus I (†536) was the bishop of Rome from 13 May 535 to his death. In 536, Agapetus traveled to Constantinople at the behest of King Theodahad of the Ostrogoths and unsuccessfully tried to persuade Emperor Justinian I to call off a Byzantine invasion of the Ostrogoth kingdom. While in Constantinople, Agapetus also deposed the patriarch Anthimus I and personally consecrated his successor who is Mennas of Constantinople. Agapetus was canonized in both the Catholic and Orthodox traditions; his feast day is 20 September in the former and 22 April in the latter.
Pope Adeodatus I (†618), also called Deodatus I or Deusdedit, was the bishop of Rome from 19 October 615 to his death. He was the first priest to be elected pope since John II in 533. The first use of lead seals or bullae on papal documents is attributed to him. He is venerated as a saint in the Eastern Orthodox Church as one of the pre-Schism "Orthodox Popes of Rome". His feast day is 8 November.
