Note 342 — Chapter XIII · THE CHURCHES OF THE EAST
Reading edition
Thus, during the seventy-five years between 1625 and 1700, there were no fewer than 50 patriarchs whose average tenure of office was a year and a half. Compare this with the long reign—seventy-two years—of Gregory XVI, Pius IX, and Leo XIII whose average tenure of office was twenty-four years—just thirty-six times as long as that of the unfortunate Patriarchs in question.
