Pier Crisologo, by the activity of other distinguished archbishops, who have united their name with a group of sacred monuments which together with those of Rome are the most representative of the Paleo-Christian art: the basilicas - among which S. Vitale and S. Apollinare in Classe stand out - and baptisteries and mausoleums.
