What is the significance of Plimpton 322?
Plimpton 322, the most famous of Old Babylonian tablets (1900-1600 BC), is the world’s oldest trigonometric table, possibly used by Babylonian scholars to calculate how to construct stepped pyramids, palaces and temples, according to a duo of researchers from the School of Mathematics and Statistics at the University …
Where is Plimpton 322 located?
Plimpton 322 is one of thousands of clay tablets dating back to the Old Babylonian period in Mesopotamia nearly 4000 years ago. It resides in the George Arthur Plimpton collection at Columbia University.

Edgar J. Banks
It was Edgar J. Banks, the inspiration behind Indiana Jones, who discovered the ancient Babylonian tablet later named Plimpton 322. He eventually sold it to publisher and collector George Plimpton for $10, and it was later bequeathed by Plimpton to Columbia University in the 1930s.
What is a Babylonian triple?
Babylonians used Pythagorean triples—a group of three positive integers a, b, and c that make the statement a² + b² = c² true—to help survey farmland.
How many primitive Pythagorean triples are there?
Of these, only 16 are primitive triplets with hypotenuse less than 100: (3, 4,5), (5, 12, 13), (8, 15, 17), (7, 24, 25), (20, 21, 29), (12, 35, 37), (9, 40, 41), (28, 45, 53), (11, 60, 61), (33, 56, 65), (16, 63, 65), (48, 55, 73), (36, 77, 85), (13, 84, 85), (39, 80, 89), and (65, 72, 97) (OEIS A046086, A046087, and …
What was the name of the man who interpreted Plimpton 322 as a list of Pythagorean triples?
In an earlier post we touched upon the notion that Pythagoras was not the first to “discover” the special relationship between the sides of right triangles and their hypotenuse.
What did Babylonians use trigonometry for?
It also indicates that the Babylonians, rather than the Greeks, were the first to make a formal mathematical study of triangles. “Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles,” continued Mansfield.
What century did Pythagoras live in?
Pythagoras, one of the most famous and controversial ancient Greek philosophers, lived from ca. 570 to ca. 490 BCE. He spent his early years on the island of Samos, off the coast of modern Turkey.

Where was the Babylonian tablet Plimpton 322 found?
The Babylonian tablet Plimpton 322 This mathematical tablet was recovered from an unknown place in the Iraq desert. It can be determined, apparently from its style, that it was written originally sometime around 1800 BCE. It is now located at Columbia University.
How tall is the Plimpton 322 tablet in cm?
Provenance and dating. Plimpton 322 is partly broken, approximately 13 cm wide, 9 cm tall, and 2 cm thick. New York publisher George Arthur Plimpton purchased the tablet from an archaeological dealer, Edgar J. Banks, in about 1922, and bequeathed it with the rest of his collection to Columbia University in the mid 1930s.
How is Plimpton 322 used as a trigonometric table?
Some have seen Plimpton 322 as a form of trigonometric table (e.g., [15]): if Columns II and III contain the short sides and diagonals of right-angled triangles, then the values in the first column are tan2 or 1/ cos2 -and the table is arranged so that the acute angles of the triangles decrease by approximately 10 from line to line. 2.
