Sirius the Dog Star: Stellar Mythology

Updated: Aug 9

Sirius, the brightest star in the sky, is a symbol of heat, fire, and fever. The appearance of Sirius heralds the hottest days of the year, when the sun's intensity is at its peak. In Egypt the Dog Star is associated with the fertile floods of the Nile.

Greek astrologers and astronomers see Sirius as a celestial representation of dogs due to its position as the principal star in the Canis Major constellation. Sirius is often referred to as 'the Dog,' also meaning the entire constellation in the night sky.


Sirius captivates the attention of many cultures throughout history. In ancient Greek mythology, Sirius is perceived as the faithful companion animal of the great hunter Orion. The Greeks associated Sirius, below and left of Orion, as his dog following him on his celestial hunts.

This association as Orion's dog adds a layer of symbolism to fierce Sirius, making it an important part of the larger mythological narrative. This star has been of great significance in various cultures throughout history.



In ancient Egypt, Sirius is associated with the goddess Isis / Sopdet. It's a key element in the Egyptian calendar due to its heliacal rise coinciding with the much-anticipated annual flooding of the Nile. Canicula and Sothis (Sopdet) are alternative names for Sirius.

Egyptian Sopdet, called Sothis by the Greeks, is instrumental in ancient Egyptian mythology as the personification of the star Sirius. In Egyptian cosmology, Sopdet is revered not only as a celestial body but also as a goddess embodying duality, nature and the divine.


Associated with fertility, the annual rising of ferocious Dog Star Sirius marks the start of the Nile flood, a crucial event for agriculture and sustenance. As Isis, Sopdet symbolizes magic, motherhood and protection. The Egyptian term for Sirius-Isis-Sopdet is Great Provider.

Her association with Anubis, the god of embalming and the afterlife, adds a funerary or chthonic aspect to her character. This merging of different divine attributes is part of the interconnection and fluidity of ancient Egyptian religion.


Through worship of Sopdet, the Egyptians honor the star Sirius and celebrate the cyclical nature of life, death, and rebirth, echoing the eternal rhythms of the cosmos. Sopdet has diverse manifestations as a star, goddess, and symbol of renewal.

Sirius has a significant place in ancient mythology and astronomy. It's closely associated with Maera, known in Ancient Greek as Μαῖρα, or 'sparkler'. In early times Maera is considered an alternate name for the dog star, Sirius.


The mythological tale surrounding Maera adds depth to the celestial connection. According to the legend, Maera is the loyal hound of Icarius, an elderly Athenian who learns the art of winemaking from wine god Dionysus.

Tragedy strikes when Icarius shares the wine with his fellow Athenians, who've never been intoxicated. The wine puts them to sleep and on waking they think they were poisoned. They kill Icarius. His devoted daughter, Erigone, is led to his body by Maera.


Overwhelmed with grief, Erigone hangs herself. Dionysus immortalizes the trio by placing them in the sky. Erigone is considered to be the archetype for Virgo the Maiden. Maera the loyal hound becomes the star Canicula, known by the Romans as Sirius.
