The story of the word

Σείριος means burning, and the Greeks meant it literally. The star rose just before the sun at the height of Mediterranean summer, and they held it responsible for the heat, the fevers and the short tempers of the season; Hesiod warns that Sirius dries out heads and knees. Rome called the period dies caniculares after the constellation of the dog, which English still translates as the dog days.
