Take the humble fly for example: the fly symbol was used at the end of the ancient Egyptian word for the insect itself, and to mean 'to fly'. Flies were also worn as protective amulets as well as symbolizing persistence: soldiers were awarded golden flies by the pharaoh as reward for heroic efforts in battle.
