This article is about the Hindu god Kasyapa. See also Mahakasyapa information on the Buddhist monk.
In Hinduism, Kasyapa ("tortoise") is an ancient god (one of the rishis), father of the devas, asuras, nagas and all of humanity. He is married to Aditi, with whom he is the father of Agni and the Adityas. He received the spoils of Parasuma's conquest of King Kaartaveerya-arjuna.
The Mahavansa, the ancient historical record of Sri Lanka, describes King Kasyapa as the son of King Dhatusena.
Kasyapa murdered his father by walling him alive and then usurping the throne which rightfully belonged to his brother Mogallana, Dhatusena's son by the true queen.
Knowing the inevitable return of Mogallana, Kasyapa is said to have built his palace on the summit of Sigiriya as a fortress and pleasure palace.
