Just a thought about the serpent biting it's tail symbol within this symbol: called "Ouroboros"
In the book of Revelation of the Bible Jesus calls himself "the Alpha and the Omega", "the beginning and the end", also in Revelation, Satan (the Dragon) is also called "the original serpent" (supposedly the one he used to lie to Eve and also from Genesis 3:15).
Could this symbol of the serpent biting it's tail be a defying message towards Jesus? Satan and his believers could possibly be saying to Jesus: "Satan is the all encompassing one not you Jesus, Satan is the beginning and the end".
Of course that's if you believe in this type of stuff. Just a thought anyways The Ouroboros symbol can be found in many things/places including one of the album covers of my very favorite music band 'RUSH' shown below.
