Hanuman, in Hindu mythology, is the monkey commander of the monkey army. His miracles are described in the great Hindu Sanskrit poem Ramayana.
As a child, Hanuman, the son of the nymph of Vayu, tried to fly and capture the sun. Which he mistook for a fruit. Indra, the king of gods, struck Hanuman (Hanu) on the jaw with a thunderbolt. Hence his name. As Hanuman continued to misbehave. Powerful sages cursed him to forget his magical powers, the ability to fly or become infinitely great, until they remembered.
