Note 8 — Book the First
Reading edition
In the Acta Consistorialia of the Vatican Secret Archives, this Pope is called Calixtus the Fourth, evidently by the stupidity of some Apostolic Scribe, who happened to know that one John, Abbot of Struma, called himself Calixtus III. (having got himself schismatically and uncanonically elected in the reign of the Lord Alexander P.P. III); and who had not the sense to know that the Holy Roman Church has the habit of ignoring pseudopontiffs and other pretenders.
