Sinus varied in accordance with the different functions the Egyptians ascribed to the star. "When they wished to signify that it opened the year, it was represented as a porter bearing keys, or else they gave it two heads, one of an old man to represent the passing year, and the other of a younger to denote the succeeding year.

Blake gives us the following interesting description of Sirius in the role of herald of the inundation of the Nile:
"This star seems to have been intimately connected with Egypt and to have derived its name from that country, and in this way: The overflowing of the Nile was always preceded by an Etesian wind (that is an annual periodic wind answering to the monsoons) which, blowing from north to south about the time of the passage of the sun beneath the stars of the Crab, drove the mists to the south, and accumulated them over the country whence the Nile takes its source, causing abundant rains, and hence the flood.

The moon was no use for this purpose, but the stars were, for the inundation commenced when the sun was in the stars of the Lion. At this time the stars of the Crab just appeared in the morning, but with them at some distance from the ecliptic, Sirius rose. The morning rising of this
