Context of Blot out
The Egyptians arrived at their estimate of the length of the solar year by observing the star Sirius. On one day in the summer this star became visible on the horizon just before sunrise. On succeeding days it was visible for a longer time before the sun‘s growing light blotted it out. The first day on which it was visible just before sunrise was known as the heliacal rising of Sirius, and the interval between two such days was about 365 1 /4 days ; so the Egyptians adopted, supposedly in 4241 B.C., a civil calendar of 365 days for the year.
