more ancient European group, known as the Solutrean culture. This style bears an uncanny resemblance to that of the Clovis tools found in the United States, which could suggest that humans may have entered America from the east over a route that has been dubbed the Atlantic Maritime route. 6.

Finally, Newbold anagrammed the letters of this senary text to produce his Latin plaintext. In April, 1921, Newbold announced the preliminary results of his solution according to this method before brilliant and learned audiences. These results stamped Roger Bacon as the greatest scientific discoverer of all time. According to Newbold, Bacon had recognized the Great Nebula in Andromeda as a spiral galaxy, identified biological cells and their nuclei, and come close to seeing the union of the sperm with the ovum. He had therefore to have not merely speculated about but to have actually constructed a microscope and a telescope and used them to make discoveries that anticipated the 20th century.
