BEFORE Britain went metric in 1972, British Imperial measurements were based on man and the harmonies of the earth.

An inch was the length of the first joint of a man’s thumb.

A foot was - you guessed it - the length of his foot.

The ell and the cubit - from fingertip to elbow.

The yard - from nose to fingertips.

According to Trish Mills during her talk on January 24, Sacred Geometry explains the fundamental laws of the universe, the relationship between everything, and everything in harmony.

Pythagoras [570–495 BC] said, ‘Numbers undoubtedly had a hand in the creation of the Universe.’

‘Geometry’ means measurement of the earth, and Trish produced many examples.

‘What is music,’ she asked, ‘but numbers and their harmonic repetition? Cymatics is sound you can see. And spirals! They comply with the rules of sacred geometry too.’

Spirals are nature’s most repeated pattern - the seeds in a sunflower, nebulae in outer space, storms and hurricanes, whirlpools, sea shells, the nautilus and ammonites to name but a few.

That lead us on to fractals, the way nature reproduces itself, increasing or decreasing but always to scale, as in snowflakes, a beautiful fern or the amazing Romanesco cauliflower.

The involute curve gives us the eagle’s beak, the dorsal fin of a shark, a sheep’s horns.

Trish compared the ancient Greek Caduceus with the structure of DNA, discovered in the 1950s, both comprised of spirals twining round each other.

‘Surely that’s too much of a coincidence to be a coincidence?’ she said.

‘The Ancient Greeks must have known about DNA.’

We see sacred geometry in architecture and art, adopted by the medieval church in the middle ages.

It brought harmony in design and composition, then Trish pointed out Euclid’s [325-265 BC] geometry in crop circles.

‘Much of crop circle geometry is very advanced and unlikely to have been known to hoaxers,’ she said, ending with a photograph of that famous crop circle that looks like the seeds in the centre of a sunflower.

‘Can you see the sunflower design?’ she asked.

“The spirals? The fractals??The involute curves?’

Sacred Geometry is everywhere you look, and there is little doubt that when early man was building Stonehenge, and the Egyptians were erecting the pyramids, they knew and understood all about sacred geometry.

Our next talk is Thursday, February 12 - Lorraine Doherty on the Bosnian Pyramids.
