Pope John III
John III was
pope from
561 to
574. A Roman surnamed Catelinus, he was of a distinguished family, being the son of one Anastasius who bore the title of
illustris. Although John reigned nearly thirteen years very little is known of his pontificate. It fell during the stormy times of the
Lombard invasion, and practically all the records of his reign have been destroyed. It is recorded in the
Liber Pontificalis that he died on
July 7, 574.
