>"On looking at the Barbary Castle pattern the ratio of the angles of the radial jumps is apparently the first ten (10) digits of the mathematical constant Pi ( the ratio of the of circumference of a circle to the diameter)

The dot after the first radial jump is even positioned correctly as the decimal point.

Take the pattern and draw radial lines from the center of the central depression though each radial jump. Take the smallest angle sector and call it one (1), then compare the other ten sectors contained angle to the smallest and pick the closest single digit for the ratio. They come out as 3.141592654.

Note that the last ratio digit has even been rounded up to four (4) since the the value of Pi out to twelve digits is 3.14159265358 and the tenth digit would normally be rounded up to four (4) if the number was only given to ten (10) places.

The significance of the three decreasing diameter circles at the end may be trying to convey the the idea that the number goes on indefinitely. The fact that the Pi decimal point is included and there is rounding up to 10 decimal places is to me a little mind boggling!”
