I do not often just buy a book that I see on a shelve, but the cover caught my attention, then the name of the author. It took a while before I read it though.
Sacred Geometry: Symbolism and Purpose in Religious Structures is an alright read. The author starts with two introductionary chapters about the principles and the forms of sacred geometry. These are the most interesting parts of the little book. The next chapters are about the application of sacred geometry in different times and cultures, like ancient Britton, Egypt, Mesopotamia, but also the Middle Ages the Renaissance and our own time. The chapters go from rather technical and mathemetical descriptions of geometry to more general observations about cultures and architects. I really had to think back of my mathemetics lessons of way back. The author even lost me on a few points. Also I fail to find the logical in the elaborate diagrams with triangles, squares and circles that supposedly explain the basis of some designs.
Most of the book is easy enough to follow though and Pennick presents a nice introduction into a nice subject.
