675. The Lives of the Popes in the Early Middle Ages (Vol. IV), by the Rev. Horace K. Mann (read 24 Sep 1961) This volume tells of the 30 Popes from Formosus, whose reign was from 891 to 896, through Gregory V, reigning from 996 to 999. Contrast the 20th century, when there were only 9 Popes--or the 19th, when there were only 6. ( )
