traces of onions recovered from bronze age settlements in china suggest that onions were used as far back as 5000 bce, not only for their flavour, but the bulb's durability in storage and transport. ancient egyptians revered the onion bulb, viewing its spherical shape and concentric rings as symbols of eternal life. onions were used in egyptian burials, as evidenced by onion traces found in the eye sockets of ramesses iv.
