Babylonian Sippar Recombination Text
Babylonian recombination text from Sippar
Old Babylonian tablet BM 85194, held by the British Museum, is a recombination text from Sippar, an ancient Sumerian and later Babylonian city on the bank of the Euphrates River. It contains problems for various kinds of solids.
Exercise 4 gives a computation rule for the volume of a circular dike with a trapezoidal cross-section. Exercises 10–13 are very brief and impossible to understand without their original context. They also show confusion by the writer between the terms ki.lá (weight) and im.lá (weight per volume). A possible interpretation of exercises 10–11 is as the weight of clay in a rectangular pit of certain specified dimensions. Problems 22, 24, 34 and 35 concern a cylinder, or silá.
