Spy, you're the one who underestands the symbolism, what's the precise meaning of this icon if used by a mason in context with other masons. I'm not asking you to speculate again about this particlular instance, but within masonry, how would this be interpreted? Is there any difference between the eye on top of the triangle/pyramid and the eye inside it? Do the rays at the top add anything specific?
To be honest I'm not the best person to ask about this sort of stuff. ViolentPanda may be your man for this (not suggesting that he's a mason but he knows a lot about it). There's tons of iconography and symbolism in freemasonry some of which is more used than others. Remember also that the All Seeing Eye was not originally a masonic symbol but one that they themselves borrowed from the Egyptians which they nicked from someone else. If you're particularly interested I can find out more for you but whenever I've come across it in freemasonry it's been used to acknowledge the fact that the Grand Architect (god to many) is observant of all our thoughts and actions. I'm buggered if I can work in any masonic connection to it being painted on Saville's house though.
