This is a graphic story of the gradual unveiling of the meaning of the Apocalypse in the light of the events of history. It traces this development through eighteen centuries, from the days of the apostolic and martyr Church to those of the mediaeval Church, the Reformation Church, and the Church of modern times. It is a history of the gradual evolution during eighteen centuries, under the influence of historical facts, of that system of interpretation which has commended itself to the most temperate and enlightened minds, Historicism.
