petrus romanis (Cardinal of Rome) should be the next Pope's name. But Vatican maffia dont allow other cardinals to choose him by their free independant votes. So as per instructions given they choose another one, but a fake one as selected John XXIII instead Cardinal Siri. So new Pope choose not other name than 'Francis I' as his official name. Just because the St. Francis of Assise was the one who had predicted about this 'last-day-incident' in early 13th century.
