Garuda literally means ‘one who flies with the help of wings’.
Significance of Garuda
One of the most common and well-known figures referred in the purāṇas is that of Garuda or Garutmān. He is pictured in a human form with two powerful wings and a sharp beak resembling to an eagle. He is the vāhana of God Viṣṇu. He is also shown as the insignia on the banner (dhvaja) of the flagpost of Viṣṇu temples.
Garuda in Ṛgveda
Garuda in Rāmāyana
In the Rāmāyana of Vālmīki, he appears once on the battlefield, when Rāma, Lakṣmaṇa and others had become unconscious due to the nāgapāśa or sarpāstra (snake-missile) discharged by Indrajit. The serpents immediately fled off when garuda came there. 
Garuda in Mahābhārata
According to the Ādiparva, Garuda was the son of the sage Kaśyapa and Vinatā. Since Vinatā had become the slave of Kadril due to a curse, Garuda liberated her from that curse by bringing the amṛta or nectar from heaven, as per the desire and condition set by Kadru. His many heroic exploits pleased Lord Viṣṇu very much hence he made Garuda his mount.
In the iconographical works, he is usually depicted as a human figure with powerful and outstretched wings at the back of the two arms. This is the pose of añjali or obeisance. Sometimes he is shown as flying and carrying Viṣṇu on his back. His two hands support Viṣṇu’s dangling feet. The color of his body may be that of an emerald or pure white. He is also decked with several ornaments.
