| Astronomical data, especially the heliacal risings of Sothis recorded by dates of their celebration in the vague year. |
| Their year originally began when the rapid rising of the Nile coincided with the rising of the star Sirius, called by them Sothis. |
| Then followed, beginning like the rest with the beginning of a Sothis period, the rule of human kings. |
| The beginning of the inundation of the Nile was marked by the rising of the star Sothis or Sirius. |
| Hence the priests of Lower Egypt commenced the reign of the seven great gods with the beginning of a Sothis period. |
| The twelve months completed, a new year began, whose birth was heralded by the rising of Sothis in the early days of August. |
