Papyrus Rylandensis 27 (ca 250 – 300 CE)


Gives rules for computing lunar latitudes and longitudes at lunar apogee, probably for
computing those quantities on an arbitrary day (omitted or lost). The zero-point of the
zodiac used is that of the Babylonian sidereal zodiac, and the epoch is 32 BCE, June 30/July
1, when the Moon was at apogee. The computation employs Babylonian numerical
methods adapted to the Egyptian 25-year calendar cycle.
