Eldest son of Upatissa III. He had sixteen brothers. When Silákála rose in revolt, Kassapa defeated him in several contests, and in the end pursued him to his stronghold in the Pácínapabbata, riding to the summit of the mountain on his elephant. This deed earned for him the title of Girikassapa. Later, while fleeing with his parents from Silákála, he lost his way and was surrounded by his enemies. Finding no way of escape he cut his throat.
