Relying on the Greek text related to Babylonian-Hellenic observations of lunar eclipses in Ptolemy's "Almagest" (Halma M., 1813) and by analysing some Arabian notes about solar and lunar eclipses -for which S.Newcomb found considerable deviations from the adopted theory -a re-analysis of his results and conclusions is herewith undertaken. The results of ancient data revision are based on Newcomb's alternative presumption that these discrepancies are caused by one or more unknown long-term
