These texts are probably from Babylon, although their exact provenance is unknown. All concern luni-solar phenomena with the exception of a text on the last visibility of Mercury, which is found on one side of a tablet whose other side deals with lunar eclipse magnitudes & longitudes. The texts fall into 2 groups. One comprises "Saros Cycle Texts," which give the months of eclipse possibilities arranged in consistent cycles of 223 mo. (or 18 years). Three of the 4 texts in this group concern lunar eclipse possibilities; the other treats solar eclipse possibilities. Included in this group is B.M. 34597, known as the "Saros Canon," which is repub. to correct errors in previous pub., & to clarify its structure. The 2nd group contains astronomical functions.
