The Ancient Roots
- In ancient Greece and Rome, people noticed that during certain times of the year, the star Sirius (known as the 'Dog Star') would rise just before the Sun.
- Sirius is part of the constellation Canis Major, Latin for "Greater Dog". When Sirius would align with the Sun, it coincided with the hottest days of summer, leading to the belief that Sirius’s appearance caused the heat.
The Solar and Star Connection
- Sirius: Brightest star in the night sky, part of Canis Major.
- Hellenistic Astrology: Posited that the ‘dog star’ contributed to a period of heat and drought, hence the phrase.
