with Euclid explaining the principles of Geometry to his friends. Full of fun, explanation and even jokes, thei is the perfect introduction to a sometimes tricky subject.

Euclid lived 2300 years ago in Alexandria, in northern Egypt. His was a brilliant mind. He devised a method of learning Geometry starting from the simplest idea - an Axiom - something we can all agree is self-evident. Euclid built argument upon argument, creating a brillaintly simple system for learning Geometry which he wrote down in his book - Euclid's Elements - which was still in everyday use in schools well into the 20th century.

Shoo Rayner brings another Mega-mind to life with wit, clarity and sensitivity. For any age that wants to get to grips with geometry.
