The bhavachakra, or wheel of life, from Buddhism.
Quote:
The wheel itself is a circle, symbolising the endless cycle of existence and suffering.
In the middle of the Wheel are the Three Fires of greed, ignorance and hatred, represented by a rooster, a pig and a snake. These are the cause of all suffering and are shown linked together, biting each other's tails, reinforcing each other.
In the next circle out, souls are shown ascending and descending according to their karma.
The next ring out is composed of six segments showing the six realms: gods, humans and Titans above and hungry ghosts, animals and those tortured in hell below.
The outer ring shows twelve segments called nidanas, illustrating the Buddhist teaching of dependent origination, the chain of causes of suffering (explained in the following section).
The wheel is held by Yama, the Lord of Death, who symbolises the impermanence of everything. The beings he holds are trapped in eternal suffering by their ignorance of the nature of the universe.
It's usually shown in a more simple wheel form, like a ship's wheel.
The Dove carrying an olive branch.
The olive branch has been used as a symbol of peace since ancient Greece and Rome. It was associated with the Greek goddess of peace, Eirene or with the Roman goddess Pax. The dove as a symbol of peace comes in with the Christians, who used it as a symbol of baptism, bringing God's peace to the person being baptised.
Sorry it's a bit big.
