Babylonian, Greek and Indian texts concerning the mathematical approximation of the periodically varying speed of the lunar motion are systematized and interpreted. Predicting lunar motion was essentially a problem of approximating a periodic zigzag deviation table at a quadratic level. The Babylonians applied arithmetical reasoning. Later the Greeks added a geometric approach. Original theories were modified in India and reached China.
