Babylonian tablets

Question

The MacTutor History of Mathematics archive writes

Two tablets found at Senkerah on the Euphrates in 1854 date from 2000 BC. They give squares of the numbers up to 59 and cubes of the numbers up to 32.

(though this has been copied, it seems, all through the Internet).

I've tried, with no luck so far, to find which tablets these were. The information is not specific enough for me to search it, for example, on cdli.

Any idea how I can find this?

Follow-up: I emailed the authors of the article but have not received a response in the 4 months since I sent it.

Answer 1

I found about 50 different sources for your quote, all verbatim copies of each other and without any indication of which those tablets were, who discovered them or any hint to catalogue numbers. I truly hate the internet sometimes, please treat this answer as a guess, there's no way to verify exactly which tablets the quote is about.

One of the tablets is (most probably) Plimpton 322 that lists Pythagorean triples and is part of the Plimpton Collection at Columbia University:

Plimpton 322 was indeed found in Senkereh, a site near the ancient city of Larsa, that's also known as Tell es-Senkereh, Tell as-Senkereh, Tell Senkereh, Sankarah, and Senkerah. Wikipedia says it was written about 1800 BC, the Rare Book and Manuscript Library of Columbia University is a lot less specific, dating the tablet between 1900 and 1600 BC, and Sherlock Holmes in Babylon asserts that the tablet's style suggests a 1600 BC origin (page 340), so the 2000 BC figure doesn't quite fit.

The 1854 figure is also bit problematic, but it roughly coincides with William Loftus' excavations in the area. Loftus discovered a few tablets, but his work in the area was rushed and under-documented, and as Edgar Banks (who later sold the tablet to George Arthur Plimpton) noted the findings were looted by locals. Without a solid record and with the tablets changing hands, I'm afraid a conclusive answer would be extremely difficult.

Another candidate would be AO 8865, a six sided prism with tables of squares, inverse squares and inverse cubes:

It has a similarly uncertain history with Plimpton 322 and it's dated at around 1750 BC.

Answer 2

You weren't kidding. I found those exact two sentences plagerized verbatim all over the Internet. Truly sad.

I did manage to find a least a couple of references with more information though.

The Handy Math Answer Book was not only original enough to modify the sentence a bit, but included some alternate dates, and a very nice extra aside about one object that may (or may not, they aren't clear) be one of the tablets. In particular, it appears to have been a big square with an x through it that "represents a sexagesimal numerical approximation of the square root of two".

That's a distinctive enough phrase that it is almost certainly the object that goes by the exciting name "Babylonian clay tablet YBC 7289":

The pictures shown in Yannis' answer don't much resemble that, but it could be that the above mentioned tablet was one of the two, and Plimpton 322 was the other.

This presentation transcript claims the two tablets were discovered by W. K. Loftus (also backing up Yannis).
