“Life is like an onion.
You peel it off one layer at a time;
And sometimes you weep.”
—Carl Sandburg, American poet
And sometimes you laugh ... that is what life is all about.
In ancient Egypt, the onion symbolized eternity because of its circle-within-a-circle structure. Paintings of onions appear on the inner walls of the pyramids and in the tombs of both the Old Kingdom and the New Kingdom.
The onion was an ancient symbol of eternity because of the concentric circles that it contains. For this reason, Russian and other orthodox churches are designed with onion domes, a bulb-shaped dome with a pointy top.
