2Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at DarkSideOfTheNet.com
When they would represent a year, they delineate
[paragraph continues] ISIS, i. e. a woman. By the same symbol they also represent the goddess. Now Isis is with them a star, called in Egyptian, Sothis, but in Greek Astrocyon, [the Dog' star]; which seems also to preside over the other stars, inasmuch as it sometimes rises greater, and at other times less; sometimes brighter, and at other times not so; and moreover, because according to the rising of this star we shew all the events of the ensuing year: 1 therefore not without reason do they call the year Isis. When they would represent the year otherwise, they delineate a PALM TREE 2 [BRANCH], because of all others this tree alone at each renovation of the
moon produces one additional branch, so that in twelve branches the year is completed.
II. ISIS SOTHIS, from the ceiling of the Ramesseion.
III. The palm branch; on which Thoth measures time.
9:1 Regulate the calendar.
9:2 Qy. A palm branch, Sharpe, 636. Clemens Alex. describing a procession, states that the Horoscopus carries a φοίνικα, which evidently must imply a palm branch. See passage of Clemens in the Appendix.
