Rhythms of world history are studied within a framework of the original authors' approaches in their possible relationship to the planetary cycles, calendar systems and Christian eschatology. The "imperial cycle" of Venus, discovered by the authors, correlates with the dates of world wars and collapses of states, acquiring religious meaning in the context of Daniel's prophecies and Philotheus's concept "Moscow is the Third Rome". Nostradamus's astrological quatrains, astronomical senses of Revelations, futurological predictions, including the theory of demographic singularity by Forster-Kapitsa and historical singularity by Dyakonov-Panov were considered. There was found the symbolic correspondence between the dates of the Jewish calendar and the events of Jewish and world history.
