Myth
The ancient Egyptians called Sirius the ‘dog star’, after their god Osirus, whose head pictorgrams resembles that of a dog. In Egypt, Sirius shines for the most of the summer, and since it is such a bright star, the Egyptians actually believed that the additional light from this nearby star was responsible for the summer heat. This of course is not true. However, the origin of the pharse ‘the dog days of summer’ comes from this ancient belief – the ‘dog star’ being root of this common saying!
