Consider the vastness of Space.

Q

The brightest star visible from any part of Earth is Sirius in the constellation Canis Major the Greater Dog. Sirius is sometimes called the Dog Star. Most people in the Northern Hemisphere notice Sirius in the southeast – south – or southwest on evenings from winter to mid-spring. February evenings are a grand time to see it. It’s also fun to spot Sirius as it ascends in the east before dawn on late summer mornings.

Although white to blue white in color, Sirius might be called a rainbow star, as it often flickers with many colors.

Historically, many cultures have attached special significance to Sirius.

Sirius, known in ancient Egypt as Sopdet or Sothis, is recorded in the earliest astronomical records. The hieroglyph for Sothis features a star and a triangle.

During the era of the Middle Kingdom, Egyptians based their calendar on the heliacal rising of Sirius, namely the day it becomes visible just before sunrise after moving far enough away from the glare of the Sun. This occurred just before the annual flooding of the Nile and the summer solstice, after a 70-day absence from the skies.

Sothis was identified with (the embodiment of) Isis, wife and consort of Osiris who appeared in the sky as Orion. Together they formed a trinity with their son Horus. The 70-day period symbolized the passing of Isis and Osiris through the duat (Egyptian underworld).

Sothis (Isis) and her husband, the god named Sah (Orion), came to be viewed as manifestations of Isis and Osiris. She was not only represented as a woman with a star on top of her headdress, but as a seated cow with a plant between her horns (just as Seshat's hieroglyph might have been a flower or a star) as depicted on an ivory tablet of King Djer. The plant may have been symbolic of the year, and thus linking her to the yearly rising of Sirius and the New Year. She was very occasionally depicted as a large dog, or in Roman times, as the goddess Isis-Sopdet, she was shown riding side-saddle on a large dog.

Sirius was both the most important star of ancient Egyptian astronomy, and one of the Decans (star groups into which the night sky was divided, with each group appearing for ten days annually). The heliacal rising (the first night that Sirius is seen, just before dawn) was noticed every year during July. Early Egyptians used this to mark the start of the New Year ('The Opening of the Year'). It was celebrated with a festival known as 'The Coming of Sopdet'.

As early as the 1st Dynasty, Sophis was known as 'the bringer of the new year and the Nile flood'. When Sirius appeared in the sky each year, the Nile generally started to flood and bring fertility to the land. The ancient Egyptians connected the two events, and so Sopdet took on the aspects of a goddess of not only the star and of the inundation, but of the fertility that came to the land of Egypt with the flood. The flood and the rising of Sirius also marked the ancient Egyptian New Year, and so she also was thought of as a goddess of the New Year.

Her aspect of being a fertility goddess was not just linked to the Nile. By the Middle Kingdom, she was believed to be a mother goddess, and a nurse goddess, changing her from a goddess of agriculture to a goddess of motherhood. This probably was due to her strong connection with the mother-goddess Isis. Not just a goddess of the waters of the inundation, Sopdet had another link with water - she was believed to cleanse the pharaoh in the afterlife. It is interesting to note that the embalming of the dead took seventy days - the same amount of time that Sirius was not seen in the sky, before it's yearly rising. She was a goddess of fertility to both the living and the dead.

In the Pyramid Texts, she is the goddess who prepares yearly sustenance for the pharaoh, 'in this her name of "Year"'. She is also thought to be a guide in the afterlife for the pharaoh, letting him fly into the sky to join the gods, showing him 'goodly roads' in the Field of Reeds and helping him become one of the imperishable stars. She was thought to be living on the horizon, encircled by the Duat. Paralleling the story of Osiris and Isis, the pharaoh was believed to have had a child with Sopdet.
