“Under the name of five kings who have fallen out of the seven, Blessed Hippolytus understands ages, of which five have already passed. The sixth, in which the Apostle saw this, is still going on, and the seventh age which follows upon the sixth has not yet come, but when it comes will not continue long…”
(The Apocalypse, Archbishop Averky Taushev and Father Seraphim Rose, p. 229)
