# Stonehenge Builders Used Pythagoras’ Theorem 2,000 Years Before It was ‘Invented’

Evidence of advanced knowledge in mathematics, astronomy, and engineering can be found all over the world, at different ancient sites.

As it turns out, the proportions between the sides of the Stonehenge triangles refer to the famous formula, according to a recently published book.

The builders of the megalithic monument—thought to be more than 4,000-years-old—used advanced geometric concepts thousands of years before they were actually ‘discovered’.

This doesn’t come as a surprise as experts have uncovered signs of its use among ancient Babylonian, ancient Chinese, and Vedic Indian cultures.

A newly published book (Megalith) by a British researcher argues that the builders of the megalithic monument of Stonehenge (United Kingdom) already knew the foundation of the famous theorem of Pythagoras, which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

“People often think of our ancestors as rough cavemen but they were also sophisticated astronomers,” John Matineau, a contributor, and editor to Megalith told the Telegraph. “They were applying Pythagorean geometry over 2000 years before Pythagoras was born.”

“We see triangles and double squares used which are simple versions of Pythagorean geometry” used in the layout of Stonehenge, Martineau said.

The book suggests that a massive Pythagorean triangle can be conceptualized between Stonehenge and two other equally important prehistoric sites in Britain.

It is believed that the British Megalithic Marvel was erected in a number of different stages sometimes between 2,000 and 3,000 BC.

And while we have come to understand many important aspects about Stonehenge, the ancient monument remains shrouded in mystery as experts are unable to unanimously conclude how or why the structure was built, thousands of years ago.

However, it is noteworthy to mention that the book—while extremely interesting and packed with incredible information—is not a research paper that’s passed peer review.

Therefore, we need more information about the builders of the monument, their techniques, and reasons to understand everything about the British archaeological jewel.

Having that said, it is still of great importance to find such a mathematical formula embedded in an ancient monument. This tells us that ancient civilizations were far more advanced than what we credit them for.
