I didn't know that they were referred to as Sun of the Sun. I do know that Sirius is the brightest star from us,and it's located in the constellation of Canis Major. It is referred to as the Dogstar. It's a small star too. The reason that it's so bright is because it is so close to us.
Its name comes from the Greek word for "searing" or "scorching," certainly appropriate for a star that shines at the bright end of the "minus-first" (-1.47) magnitude. Sirius is the luminary of the constellation Canis Major, the Greater Dog, which represents Orion's larger hunting dog, and as such is commonly referred to as the "Dog Star." So great is its prominence that it has two "announcer stars" that from the mid- northern hemisphere rise before it, Procyon and Mirzam. Famed from times long past, the first glimpse of Sirius in dawn announced the rising of the Nile in ancient Egypt. (It no longer does because of precession, the 26,000-year wobble of the Earth's axis.) Sirius is also part of a large asterism, the Winter Triangle, the other two stars of which are Betelgeuse in Orion and Procyon in the smaller dog, Canis Minor.

According to Bernadette Brady, Sirius is one of the great stars of the sky. The Egyptians called it The Shining One or The Scorcher and it was linked with the life-giving waters of the Nile. Brady, in Starlight tells us Sirius is the marker of great deeds where, through the individual being sacrificed to the collective expression, the mundane can become sacred, where the small action of the individual may have a large effect on the collective.
The centre of Egyptian civilisation was the Nile. Flooding every year at the same time, it provided rich soil for agriculture. The Egyptian astronomers, who were actually priests, recognised that the flooding always occurred at the summer solstice, which also just happened to be when the bright star Sirius rose before the sun. By interpreting and using this information, the priests were subsequently able to predict the annual flooding, a skill which in turn rendered them considerable power. The year was divided into twelve 30 day months, followed by a five day feast period. Because the Egyptian calendar did not have leap years, it cycled through the seasons completely every 1460 years. The period that elapsed between these risings is known as the "sothic cycle". Over ancient Egypt's history, the months completely rotated through the seasons at least twice due to this quarter day discrepancy. http://www.egyptologyonline.com/astronomy.htm
