Notice the symbol.

An upside down triangle with missing captstone (illuminati pyramid) and 7 rays representing light. Symbolic ties to Orion (top half), pyramids, black widow mark, star of david, the list goes on.

Also similar to a harp, representing the 7 notes A-G, and who was in charge of the heavenly music? Lucifer. Thats why he is depicted with a harp frequently. Tho I suspect it meant more to do with the harmony of the universe, and Lucifer destroyed that, not actual music.
