So this

The Greek form of the Egyptian word for Sirius, the brilliant star in the constellation Canis, from whence its name the dog-star, perhaps the most important star known to Egyptian astronomers. Its importance also to the modern chronologer can hardly be over-estimated, for the Egyptian calendar was arranged by the heliacal rising of So this. The star was personified as a godde , and frequently represented, especially in the Graeco-Roman temples, as a cow. She is queen of the thirty-six constellations recorded in old astronomical tables, and was the star of Isis. Part of the temple at Dendera was devoted to the festivals in honour of the rising of So this. (See Year .)
