Nanda and Yashoda pushing baby Krishna on a swing.
Nanda (also known as Nandagopa), according to the Harivamsha and the Puranas, was the head of the Gopas, a tribe of cowherds referred as Holy Gwals. Vasudeva, took his new-born son Krishna to Nanda on the night of the child's birth so that Nanda could raise him. Nanda, who was married to Yasoda, brought up both Krishna and Balarama. Krishna derives his name Nandanandana (meaning son of Nanda) from him.
