This legend is found on a tablet marked K, 3,657, in the British Museum.
The story which the tablet contains appears to be the building of some
great temple tower, apparently by command of a king. The gods are angry at
the work, and so to put an end to it they confuse the speech of the
builders. The tablet is in a very broken condition, only a few lines being
in any way complete.
The late Mr. George Smith has given a translation of the legend in his
work on Chaldean Genesis, and I have published the text and translation in
the fifth volume of "Transactions of the Society of Biblical Archæology."
