Feral children, children who have lived from a young age without human contact, appear in mythological and fictional works, usually raised by animals. Often their dual heritage is a benefit to them, protecting them from the corrupting influence of human society, such as in Tarzan's case. It may also permit the development and expression of their own animal nature, for example Enkidu, or providing access to the wisdom and lore by which animals survive in the wild, for example Mowgli.
