In Asia, Cranes are symbols of longevity and immortality. The White Crane can fly to the heavens and it is a Chinese symbol for "wisdom" and is sometimes called the "heavenly" or "blessed" Crane. Cranes were vehicles of the gods and in China fly them to the "Isle of the Immortals", the legendary home of the eight immortals. A Crane's eggs were used in magic potions to grant eternal life upon its drinkers.
In many parts of the world, Cranes are regarded as a messenger of the gods. In ancient Egypt, legend says that a two-headed crane was once seen flying over the Nile, to announce a new age of joy and prosperity.
Cranes are masters at killing snakes, thus, in Christian symbolism, they were seen as natural enemies of Satan.
