Ancient connection to Sirius II

The  Egyptian hieroglyph representing Sirius has been esoterically interpreted to be a representation of this cosmic trinity.

This concept is so crucial for Freemasons, that it was embedded in some of the most important structures in the world. As stated by Albert Pike above, the Egyptian god Horus and the star Sirius are often associated.

In Masonic symbolism, the eye of Horus (or the All-Seeing Eye) is often depicted surrounded by the glittering of light of Sirius.

Given the symbolic correlation between the All-Seeing Eye and Sirius, the next image becomes self-explanatory.
