This paper derives a legendary -1356 Jan 26 SS-Gm-GZT with aid of precession, and tropical and Venus leap days, and while details of this knowledge are lost to us, a legacy of astronomical computations persists in astro-calendric structures in all Long Count dates as an astronomical repository, accessed by a period residual arithmetical methodology embedding calendric proper fractions. Stela-1 teaches Long Count with aid of astro-calendric structures serves as an astronomical repository of the past, with astronomy preserved for posterity accessible by computations rather than descriptive textural repositories. Deep time mythological Venus leap day patterning underpins Stela-1’s contemporary triple locked embedded Venus cycle, showing intent and precision in selecting the Stela’s Period Ending Long Count interval to the Epoch, along with a forward Venus Round for a net 2365 Venus cycles to the remote past. Tulum’s Diving God suggests Monte Alban’s upside down heads are not deposed rulers of subjugated places but rather a diving deity, and the entire Citadel is now cognized as an astronomical observatory implicated in Long Count’s inaugural launch. Venus astronomy played a commanding role in the Long Count’s inauguration, and this paper presents the simplicity deriving from Venus leap days in computations.

Keywords Ordovician Orbital forcing Astrochronology Cyclostratigraphy Biostratigraphy Review of current progress in Mid to Late Ordovician astrochronological studies exposes some important issues related to cyclostratigraphical studies, including the completeness and correlation of successions, and the connection between inferred astronomical cycles and geological events recorded in the sedimentary record. While bulk, low-field, mass specific magnetic susceptibility methods are widely applied in studies of high resolution cyclostratigraphy, they require close support from sequence stratigraphy and biostratigraphy, and should be linked back to outcrop patterns. Otherwise they risk distortion in the calibration against geological time, through lack of anchoring to well-defined biostratigraphical horizons and unrecognised condensed intervals and larger hiatuses. A significant limitation currently is that few high-resolution radio-isotope ages are linked to well-defined biostratigraphical boundaries. Nevertheless, fourth order sedimentary sequences linked to 405 ky orbital eccentricity cycles, and longer orbital cyclicity impressed in third-order sequences, represent good grounds for development of a reliable astrochronological scale. The astrochronologically calibrated sequence-stratigraphical record documented from high latitude Gondwana shows significant impact from orbital forcing on the Mid to Late Ordovician global climate.

The article demonstrates how lunar phases and heliacal risings of Sirius can be calculated and used for fixing points of pharaonic absolute chronology. Specific dates dealt with are the lunar dates of Amasis’s year 12 and of the Battle of Megiddo, as well as the series of lunar dates and the Sirius date in the Illahun archive. General problems considered are: (1) the beginning of the Egyptian lunar month on the day after last crescent; (2) the emendation of the date of the Battle of Megiddo; and (3) the methodological confusion arising from the fact that the Illahun Sirius date is predicted, but was calculated as if the star’s rising were observed. Technical astronomical topics include: (1) visibility criteria for old and new crescent; (2) the erroneous check of visibility criteria by Fatoohi, Stephenson & Al-Dargazelli; and (3) the partial repetition of the same lunar phase in shifts of 25 Egyptian years. The appendix consists of letters by the astronomer F. Hinderer to the mathematician B. van der Waerden relating to the latter’s erroneous correction of P. V. Neugebauer’s calculation of new and old crescent, published in 1942 (a mistake repeated by the phycicist L. W. Casperson in 1986).
