Following this thread with quite a bit of interest. Going to throw in these bits of information to see where it takes the conversation.
The well-known "Eye of Horus" is not always that. Very similar in appearance is the Eye of Ra, which is considered a feminine aspect of the god Ra. Both are sun gods, but Ra is a forerunner of Horus (someone mentioned that Horus is the son of Isis. Ra is the first being, the one that originated the Ennead which include Isis.) People tend to be more informed about Horus than Ra, so here's a bit of information on that (I'd recommend reading through the whole page):http://www.egyptological.com/2011/04/ey ... horus-1155
In the Heliopolis creation myth the creator deity is Atum, or Atum-Ra, later identified simply as Ra. Ra created two children, a male, Shu (air) and his sister Tefnut (moisture). Shu and Tefnut in turn produced Geb (the earth) and his sister Nut (the sky). The children of Geb and Nut were Osiris, Isis, Seth and Nephthys. Between them they were known as the Heliopolis Ennead (or nine). Geb and Nut were forced apart by their father Shu to produce the sky above, the earth below, and the air and moisture between them – the realm of living humans. In a version of the creation myth dating back to the Old Kingdom Pyramid Texts, Shu and Tefnut became lost in the Primeval Sea. Ra sent his eye to search for them. When the Eye returned she was so grieved to see that Ra has replaced her with a new eye that she shed tears. Her tears gave birth to humanity. Thereafter, when the eye goddess was at Ra’s side, she took the form of a serpent coiled on the deity’s forehead, poised to fight his enemies, now known as the uraeus and best known from the Eighteenth Dynasty golden mask of Tutankhamun, although images of the uraeus are known from as early as the First Dynasty. The Eye of Ra was always able to leave Ra, to act as a servant of the god Ra in the form of an eye goddess.
In some accounts of the story of Horus, the left eye of Horus (the lunar eye) is called the "Eye of Thoth." The right is the "Eye of Horus" (sometimes confusingly called the Eye of Ra in reference to the solar aspect but not they are not the same thing). The left and right eyes of Horus are considered inverses, opposites of one another, the feminine and masculine parts of a greater whole. The left (the moon or evening star) would be associated with concepts of healing and restoration, while the right would be power and perfection (the sun or the morning star). These concepts coexist on the face of Horus, much like a ying yang.
To further confuse, the positioning of the eyes is not a surefire way to know which eye is which. But it can be sometimes. For those who have said the eye is reminiscent of the dollar bill Eye of Providence, it's worth noting that Bob's eye and the dollar eye would occupy opposite sides of the face.
Dollar Bill (Eye of Providence)
Eye of Horus
There seems to be a consensus in referring to the Eye of Providence as a descendant of the Eye of Horus, so matter which way the eye is facing we can likely just refer to it as an Eye of Horus (the right, masculine side). As for the Masonic connection, the Eye of Providence is a very well-known symbol used by the Freemasons, but keep in mind they didn't invent it; so while the relation is
there, one does not necessarily mean the other.
As for Bob's symbol, that's up in the air. Anyway, this is just a little information to add variety to the discussion.
