Lecture for the Summer School "Application of Informational Technologies to Biblical Studies" July 27 - August 7, 1998 - Sofia, Bulgaria Dating the Apocalypse using Computational Astronomical Methods -------------------------------------------------------------- Emil Kelevedzhiev Institute of Mathematics and Informatics, Bulgarian Academy of Sciences, Sofia, Bulgaria e-mail: keleved@math.acad.bg Abstract -------- Many discussions about the Bible and especially about the book of Revelation (the Apocalypse) concern the date of writing. In some cases efforts to determine these dates take precedence over the substance and application of the books. In searching for the date when a book of Bible was written, we must consider both internal and external evidences. By internal, we mean, evidence contained within the book. Following the Fomenko's ideas we make an attempt to interpret some of the fantastic pictures, described in the book of Revelation as an observation of the night stellar sky. Looking at any medieval astronomical map, we may see almost the same set of monsters and animals, which are presented in the text of the Apocalypse. In the Middle Ages astronomy the constellations and planets were traditionally pictured as such like symbols, now preserved in astrology. Deriving by analysing the text of Revelation a location for each planet in a respective ecliptic constellation, we can find a moment in the past historical time, when this distribution occured. That may be done by the help of a computer using the exact computational methods of celestial mechanic. Providing computations we found that the given positions of the planets might be realized only at the following years A.D.: 395, 632, 1249 or 1486. This result remains disputable and contradictory to the commonly accepted view of early dating of Apocalypse from the time of the Roman Emperors Nero (54-68 A.D.) up to Domitian (81-96 A.D.).
