Donald W. Patten (1929-2014) was an American researcher and keen supporter of catastrophism. He was also a dedicated creationist. His cosmological theories were comparable to those of Velikovsky, who claimed that some of the planets in our Solar System were rearranged within the memory of man. This reorganisation involved a number of damaging close encounters by some planets with the Earth. While Velikovsky was to a great extent focused on the movements of Venus, Patten was more concerned with the activities of Mars.
>Stuart Harris noted in a 2017 paper(c) that “Donald W. Patten modeled flybys of Mars as a fIxed sequence that alternated spring and fall, spaced 108 years apart. He sequenced flybys from 701 to 1404 BCE using historical records. Flybys altemated between the night of March 20-21 on odd years, and during the day of October 24 on even years.”
Harris’ paper “extends Patten’s methodology to March 7137 BC by recognizing that the 108-year interval was not constant but occasionally increased in increments of four years. Two important milestones are March 3161 BC, the Biblical Flood, and March 3761 BC, the start of the Hebrew calendar.”<
Patten wrote a number of books and papers, two of which were with Samuel R. Windsor entitled The Recent Organisation of the Solar System, and The Mars-Earth Wars, which are also available online(a)(b).
