Aldenwater egg geometry reveals nine-fold and Pythagorean construction methods. Two circles constructed using Pythagorean triangles Top and bottom circles divided into nine equal parts Equilateral triangles inside both circles create nine-pointed star geometry

Alen water's egg-shaped stone circle reveals sophisticated use of Pythagorean triangles to construct two circles, both divided into nine equal parts. Equilateral triangles within create nine-pointed star geometry, with the top circle's 2/9 positions coinciding precisely with corresponding points below. Alexander Thom's measurements show these Pythagorean methods for establishing right angles are still used by UK builders today — a technique stretching back over 5,000 years.

Key Facts

  • Two circles constructed using Pythagorean triangles
