The Patriarchs referred to in Genesis and their seemingly exaggerated longevity have been a source of continuous debate ever since biblical criticism developed in the 18th century. Cornelius de Pauw referred to the apparently exaggerated life spans of the biblical patriarchs explaining that it was widespread in the Middle East and further afield to name a dynasty or family after its founder and attribute the total years of its reign to that founder.

Emilio Spedicato in a paper(f) entitled Large Numbers in Asian Chronology Decrypted includes some radical ideas on how to resolve the mystery of the ages of the patriarchs recorded in the Bible.
A paper(a) by an unnamed and apparently deceased author was published by Duane L. Christensen. It approaches the ages of the patriarchs from a numerological standpoint with some curious conclusions. I’m wary of all such occult claims but will leave it to readers to decide.
Another paper by Dean Talboys, entitled Methuselah Debunked(b)(c)(d) offers a convoluted explanation for the ages based on Babylonian astronomy/astrology.
>Philip Coppens has also touched on a possible astronomical explanation for the patriarchal numbers(g).<
