Late Babylonian astronomical procedure texts and tabular texts are the oldest evidence of mathematical astronomy. Then again, Late Babylonian astronomy forms the last and probably the most remarkable phase of intensive and varied occupation of the Mesoptamian people with celestial phenomena. This is evidenced by an extensive textual corpus, which is conventionally divided into three areas, astrology (omina and horoscopes), observational astronomy (star lists, Saros texts, astronomical diaries, goal year texts, almanacs, etc.), and mathemetical astronomy (procedure texts, synodic tables, and auxiliary tables). About 85 procedure texts, 200 synodic tables, and 40 auxiliary tables have been published to date. In the meantime, the number of unpublished procedure texts and synodic tables has increased to approx. 130 and 210 respectively.
