Note 46 — ST. MARK'S CHURCH[46]
Reading edition
From "The Stones of Venice." St. Mark's is merely a church. It is not a cathedral; that is, it is not the "cathedra" of a bishop. Originally it was the private chapel of the Doge. Likewise, St. Peter's at Rome is a church only—the church of the Pope. The cathedral of the Pope (who is the Bishop of Rome), is St. John Lateran.
