Pythagorean Theorem Found On Clay Tablet 1,000 Years Older Than Pythagoras

Last updated on 21 AUG 2024

Imagine a world where our mathematical truths, the ones we’ve etched into the very foundation of our education, hold secrets that stretch even further back in time than we ever thought possible. Among these truths, the Pythagorean Theorem stands as a monumental pillar in the world of mathematics, a theorem that has frustrated students and delighted mathematicians for centuries. Typically, we credit this theorem to the ancient Greek philosopher Pythagoras, a name synonymous with triangles and their mystifying properties. But what if the roots of this mathematical principle reached back not just a few centuries before Pythagoras but over a millennium? This revelation not only reshapes our understanding of mathematical history but also invites us to explore the depths of human intellect in the ancient world. Join us as we unravel a story that bridges time and civilizations, shedding light on a piece of knowledge that has traversed through ages to reach us.

The Discovery of Ancient Wisdom

Our journey begins with an unassuming artifact, a clay tablet known by its catalog number IM 67118. This ancient Babylonian tablet, dating from 1770 BCE, has stirred the pot of historical and mathematical debates. Unlike any ordinary piece of clay, this tablet holds within it calculations that echo the famed Pythagorean theorem, suggesting that Babylonian scholars grasped the essence of this mathematical truth well over a thousand years before Pythagoras was even born. The tablet, believed to have served an educational purpose, showcases the lengths and breadths of a rectangle’s diagonals in a manner that unmistakably parallels the Pythagorean theorem. This discovery is not just a testament to the Babylonians’ mathematical prowess but also a puzzle piece in understanding the evolution of mathematical thought.

Understanding Babylonian Mathematics

The ancient Babylonians were not just pioneers in the realm of architecture and astronomy; their mathematical acumen was equally advanced, if not revolutionary. Their civilization, flourishing in what is now modern-day Iraq, developed a counting system based on the number 60, a system that has endured through the ages to influence how we measure time and angles today. This base 60, or sexagesimal system, allowed them to perform complex calculations with a precision and ease that was unparalleled in the ancient world.

Another fascinating artifact, a tablet dating from around 1800–1600 BCE, offers further evidence of their mathematical sophistication. This tablet features a square with labeled triangles inside, revealing that ancient mathematicians had a deep understanding of geometric principles, including those encapsulated by the Pythagorean theorem. When the markings on this tablet were translated from their base 60 notation, it became clear that these mathematicians knew the relationship between the length of a square’s diagonal and its side, essentially understanding the square root of 2. This discovery was groundbreaking because it indicated that the Babylonians were aware of irrational numbers, a concept that would not be firmly established in the mathematical world until the Greeks.

Bruce Ratner, in his exploration of this topic, emphasizes the Babylonians’ familiarity with what we now recognize as the Pythagorean Theorem. His research suggests that this knowledge was not an isolated insight but a fundamental part of their mathematical toolkit, especially in their construction and surveying practices. This revelation underscores the sophistication of Babylonian mathematics, revealing a culture that not only valued mathematical inquiry but also possessed an understanding that would not be matched for centuries.

With this backdrop of Babylonian mathematical prowess, we move closer to unraveling the mystery of how the Pythagorean theorem came to be associated with a Greek philosopher born centuries later.

The Real Origin of the Pythagorean Theorem

The narrative surrounding the Pythagorean theorem, a cornerstone of geometry, is as much about the origins of mathematical thought as it is about the theorem itself. The story takes an intriguing turn with the Babylonian clay tablets, which not only predate Pythagoras by a millennium but also compellingly suggest that the theorem was part of a much older mathematical tradition. Mathematician Bruce Ratner’s paper illuminates this perspective, offering a deep dive into the Babylonian understanding of geometry and numbers.

Ratner’s analysis of the Babylonian tablets, particularly the one known as IM 67118, showcases a civilization that had not only conceptualized the theorem but had applied it in practical contexts. The Babylonians’ grasp of geometric principles, especially the relationship between the sides of a right-angled triangle and the square root of 2, highlights an advanced mathematical culture. This finding is pivotal because it introduces the possibility that the theorem, long attributed to Pythagoras, was actually part of a collective knowledge that spanned across civilizations and was passed down through generations.

The acknowledgment that the Babylonians understood the theorem in its form (d2 = a2 + a2 = 2a2) for the diagonal of a square, underscores the theorem’s real origins in ancient mathematical practice. This was not merely theoretical knowledge but a practical tool for architects, surveyors, and scholars of the time. The Babylonians’ familiarity with irrational numbers, as evidenced by their handling of the square root of 2, marks a significant milestone in the history of mathematics. It suggests a level of abstraction and reasoning that forms the bedrock of modern mathematical thought.

Ratner’s work sheds light on a critical aspect of mathematical history: the dissemination and attribution of knowledge. The fact that the theorem’s origins can be traced back to Babylonian mathematicians challenges the traditional narrative and invites us to reconsider the contributions of ancient civilizations to our contemporary understanding of mathematics.

Pythagoras and His Legacy

Pythagoras, a figure shrouded in mystery and legend, has long been celebrated as a pioneering mathematician and philosopher. His contributions to mathematics, particularly the theorem that bears his name, have cemented his place in history. However, the revelation that the Pythagorean theorem predates him by over a thousand years raises fascinating questions about knowledge, attribution, and legacy in the ancient world.

Pythagoras founded a school in southern Italy, known as the Semicircle of Pythagoras, which became a center for philosophical and mathematical inquiry. This community was somewhat secretive, with teachings passed down orally among its members. This method of knowledge transmission, coupled with the scarcity of writing materials, meant that much of what was learned within the Pythagorean circle was attributed to Pythagoras himself, out of respect for his leadership and teachings.

Mathematician Bruce Ratner points out that the absence of original writings from Pythagoras complicates our understanding of his contributions. The practices of the Pythagoreans, including attributing discoveries to their founder, have led to a historical conflation between man and mathematics. This tradition of ascribing mathematical findings to Pythagoras, regardless of their true origins, underscores the complexities of ancient intellectual property and the preservation of knowledge.

The Pythagorean school did more than just popularize the theorem; it became a crucible for mathematical and philosophical ideas that would influence Western thought for centuries. While Pythagoras may not have been the first to discover the relationship between the sides of a right-angled triangle, his legacy and the community he built played a pivotal role in the development and dissemination of mathematical concepts.

The association of the theorem with Pythagoras, despite its earlier Babylonian origins, is a testament to the enduring impact of the Pythagorean tradition. It reminds us that the history of mathematics is not just a collection of equations and proofs but a tapestry of stories, personalities, and cultures that have contributed to our understanding of the world.

As we reflect on the legacy of Pythagoras and the ancient Babylonians, we are reminded of the fluidity of knowledge and the importance of recognizing the contributions of all civilizations to the collective human endeavor of understanding the universe. The story of the Pythagorean theorem, far from being a simple mathematical formula, is a narrative about the human capacity for curiosity, discovery, and the sharing of wisdom across generations.
