I recently discovered a remarkable publisher, "Wooden Books", with small, inexpensive volumes that bring together an impressive collection of historical and modern visual wisdom from prehistoric times onwards. A few examples:
"Sacred Geometry" by Miranda Lundy -- the secret visual language underlying much architecture and art from the earliest times to the present.
"Li - Dynamic Forms in Nature" - the ancient Chinese word for the main families of natural design, special patterns with names like "Anfractuous", "Nubilous", "Filices"... food for visual metphor use!
"Earth Grids - The secret patterns of Gaia's secret sites" - this is particularly mind-blowing book talks about theories on the geometry of the distribution of sacred sites all over the world, some dating back 12,000 years.
I trust I have whetted your curiosity and encouraged you to integrate this ancient knowledge into our contemporary search for meaning and planetary harmony! Why reinvent the wheel...
