Excerpt:
Although the numerical methods and parameters found in the Babylonian Astronomical Procedure texts and Ephemerides of the Seleucid Era [310 B.C. - 75 A.D.] have been described in some detail, notably by Neugebauer (1955),1 (1975), 2 Van der Waerden (1974) 3 and others, it is far from certain whether the extant material represents the state of Babylonian astronomy per se, or merely scattered remnants of a larger corpus of knowledge.
