Plimpton 322: a Babylonian table and its interpreters
Plimpton 322 is a clay tablet filled with columns of numbers. We can read them, but scholars still debate why the table was made.
What Plimpton 322 shows
Columbia University Libraries, which hold the tablet in the Plimpton collection, identify Plimpton 322 as created around 1800 BCE and note its mathematical significance. The research record treats it as an established object with an approximate date that still needs a refined scholarly dating range. Columbia University Libraries ↗
Numbers first, meaning second
The tablet's columns are directly visible. What they were for is a separate claim layer: the record explicitly keeps the interpretation of mathematical purpose apart from the object's description. Several readings exist, and the tablet does not announce which one is right.
What can you see on Plimpton 322?
Write down what can be observed: material, layout, the sequence of numbers, a broken edge. Then list what each interpretation adds. A persuasive modern reading should explain the observed features better than its rivals, not just fit them.
Would a new date change the interpretation?
If the dating is refined by even a century, which interpretations would be affected, and which depend only on the mathematics?
