Apocalipse 17:10

And there are seven kings: five are fallen, and one is, and the other is not yet come; and when he cometh, he must continue a short space.

And they are seven kings — Anciently there were royal palaces on all the seven Roman bills. These were the Palatine, Capitoline, Coelian, Exquiline, Viminal, Quirinal, Aventine hills. But the prophecy respects the seven hills at the time of the beast, when the Palatine was deserted and the Vatican in use. Not that the seven heads mean hills distinct from kings; but they have a compound meaning, implying both together. Perhaps the first head of the beast is the Coelian hill, and on it the Lateran, with Gregory VII. and his successors; the second, the Vatican with the church of St. Peter, chosen by Boniface VIII. the third, the Quirinal, with the church of St. Mark, and the Quirinal palace built by Paul II. and the fourth, the Exquiline hill, with the temple of St. Maria Maggiore, where Paul V. reigned. The fifth will be added hereafter. Accordingly, in the papal register, four periods are observable since Gregory VII. In the first almost all the bulls made in the city are dated in the Lateran; in the second, at St. Peter's; in the third, at St. Mark's, or in the Quirinal; in the fourth, at St. Maria Maggiore. But no fifth, sixth, or seventh hill has yet been the residence of any Pope. Not that the hill was deserted, when another was made the papal residence; but a new one was added to the other sacred palaces. Perhaps the times hitherto mentioned might be fixed thus: - 1058. Wings are given to the woman1077. The beast ascends out of the sea1143. The forty-two months begin1810. The forty-two months end1832. The beast ascends out of the bottomless pit1836. The beast finally overthrown. The fall of those five kings seems to imply, not only the death of the Popes who reigned on those hills, but also such a disannulling of all they had done there, that it will be said, The beast is not; the royal power, which had so long been lodged in the Pope, being then transferred to the city.

One is, the other is not yet come — These two are remarkably distinguished from the five preceding, whom they succeed in their turns. The former of them will continue not a short space, as may be gathered from what is said of the latter: the former is under the government of Babylon; the latter is with the beast. In this second period, one is, at the same time that the beast is not. Even then there will be a Pope, though not with the power which his predecessors had. And he will reside on one of the remaining hills, leaving the seventh for his successor.
