I first read John Michell's "The New View Over Atlantis" about 25 years ago. I was too young to appreciate it at the time; to me it seemed like hippy nonsense trying to pass itself off as some kind of ancient science through the allure of Arthurian legend. Reading it again many years later, I was able to appreciate that a great deal of ancient wisdom is passed down through generations of ignorance precisely because it was successfully hidden and blended into myth and legend. Many numbers, and the relationships between them, are significant not because they are derived from the words and numbers our ancestors choose to use - but very much the other way around - our ancestors derived words and numerical relationships from observing and measuring the earth and the heavens.
In "The Dimensions of Paradise" Michell continues to expound on a lifelong theme - that ancient civilizations had an incredible level of science and technology. Specifically, they understood geometry and mathematics, used them to obtain accurate measurements of the earth, the moon, and the sun, along with the distances between them. The ancients did not merely know these measurements (better than we did until quite recently) and express them in their original units of measure; they created systems of measurement based on known lengths, defining units in proportion to the cosmos. So it is should not be surprising to see examples where our ancestors used these measures and relationships to build monuments around the world. It was not just a vain attempt to recreate heaven on Earth; it demonstrates harmonics that work on the scale of stars and planets and moons, right down to pleasing forms in pyramids, temples, and calendar-stones. The same numbers, proportions, and ideas are also expressed in mythical construction around the world, from Plato's Magnesia and Atlantis to the Bible's New Jerusalem and beyond.
Because of the numerous forms these measures took in ancient expression, we can more easily rediscover their knowledge after dark ages of forgotten wisdom. We are forced to recognize that many ancient units of measure, and even the English units still used today, are derived from the same system. "The Dimensions of Paradise" is an excellent introduction to sacred geometry, gematria, and ancient systems of measure. But it is not light reading and a good background in ancient history and mythology will help readers appreciate Michell's exposition of ancient wisdom. As an author myself, I will say that these two books were of great help to my own writing efforts, as the knowledge Michell reveals allowed me to synthesize many related ideas over a broad range of topics.
Anyone interested in these topics may also want to read books like Hapgood's "Maps of the Ancient Sea Kings," Weidner and Bridges' "The Mysteries of the Great Cross of Hendaye," and de Santillana and von Dechend's "Hamlet's Mill." Many unusual numbers that stand out in the Bible, and throughout world mythology, will also take on new meaning after reading Michell's work.
