For centuries, the name Pythagoras has been synonymous with the Pythagorean theorem. This fundamental principle of geometry, taught to high school students the world over, states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). It’s a cornerstone of mathematics, but did Pythagoras actually discover it, or were there others before him who understood this fundamental relationship?
Recent research sheds light on the ancient Babylonians and their potential role in the origin of the Pythagorean theorem. While it is widely believed that Pythagoras, the Greek mathematician, formulated this theorem around 2,500 years ago, evidence suggests that the concept might predate him by several centuries.
A study conducted in 2009 highlighted the possibility that the ancient Babylonians were well aware of the principles that would later be known as the Pythagorean theorem, although it was not referred to by that name at the time. This theorem is also known by various names, including Pythagoras’ Theorem and Euclid I 47.
The real surprise comes from deciphering ancient Babylonian tablets, which suggest that they were already using the principles of the theorem. One notable tablet, IM 67118, is estimated to date back to 1770 BC, a time long before Pythagoras was born.
This tablet, along with another one dating back to 1800-1600 BC, contained diagrams and mathematical notations that, when interpreted using the Babylonians’ base 60 counting system, unveiled their understanding of the Pythagorean theorem.
The groundbreaking discovery on the Babylonian tablet IM 67118 revealed a crucial piece of information. It displayed the formula d = √2, where “d” represents the length of the diagonal of a square, and “2” signifies the ratio of the diagonal to the side length. This discovery implies that the Babylonians were already aware of the Pythagorean theorem or, at the very least, a special case of it related to the diagonal of a square.
Bruce Ratner, a mathematician, emphasized the significance of this finding. He stated, “The conclusion is inescapable. The Babylonians knew the relation between the length of the diagonal of a square and its side: d = √2.” This particular number, the square root of 2, is known to be irrational and holds a central role in the Pythagorean theorem.
What’s even more intriguing is that this knowledge would have predated Pythagoras by over a millennium. The scarcity of written records from that time makes it challenging to definitively establish who first conceived these mathematical concepts. It’s possible that Pythagoras’ contributions were passed down orally through generations, and the Greeks eventually attributed the theorem to him out of respect for their leader.
This revelation raises an important question about the history and evolution of mathematical knowledge. Did Pythagoras truly discover the Pythagorean theorem, or was he merely a custodian of ancient wisdom that was already in circulation long before his time? The answer to this question could reshape our understanding of the development of mathematics and the transmission of knowledge in ancient civilizations.
In conclusion, while Pythagoras is undeniably celebrated for his contributions to mathematics, it appears that he might not have been the original author of the Pythagorean theorem. The ancient Babylonians, with their advanced mathematical understanding and the discovery of tablets predating Pythagoras, challenged the conventional wisdom regarding the origins of this fundamental geometric concept.
As we continue to explore the annals of history, we must remain open to the possibility that knowledge often emerges from collective wisdom, rather than the genius of a single individual. The question of whether Pythagoras truly discovered the Pythagorean theorem invites us to reevaluate the foundations of mathematical history.

While most individuals who have delved into geometry can recall some aspect of the Pythagorean Theorem, the intriguing tale of Pythagoras and his renowned theorem remains relatively obscure. This article aims to shed light on key plot points within this narrative. The famous theorem is known by various appellations, some rooted in the context of its time, such as the Pythagorean Theorem, Pythagoras’ Theorem, and notably, Euclid I 47.
Widely regarded as the most iconic proposition in mathematics, it also ranks as the fourth most aesthetically pleasing equation. Surprisingly, there exist more than 371 distinct proofs of the Pythagorean Theorem, initially compiled in a book in 1927.
These proofs include contributions from notable figures like a 12-year-old Einstein, who would later employ the theorem in his groundbreaking work on relativity, as well as Leonardo da Vinci and the U.S. President, James A. Garfield. Pythagoras is forever associated with the discovery and proof of this eponymous theorem, despite the absence of concrete evidence supporting his direct involvement.
In fact, historical records indicate that Babylonian mathematicians had uncovered and proven the Pythagorean Theorem a millennium before Pythagoras’ birth.
