Result

Kassapa seized the throne and had his father killed; the rightful heir Moggallana fled to India.

01“This is all my wealth”

The Culavamsa tells the story plainly. Kassapa imprisoned Dhatusena and demanded the royal treasure. The old king asked to be taken to the Kala Wewa, the reservoir he had built. He bathed in it, drank its water, and told the messengers that this was all the wealth he had. Kassapa, enraged, had him stripped, chained and walled up. Migara, who held a grudge against the king, saw it done. Prince Moggallana, the heir, escaped across the sea to Jambudvipa.

02The fortress on the rock

Fearing his brother’s return, Kassapa moved his court to Sigiriya, a granite rock rising some 200 metres from the forest. He built a palace on its summit, gardens and pools at its foot, and a gateway through the paws of a great stone lion. The painted women on its western face, and the graffiti verses left by visitors over the following centuries, survive. He ruled about eighteen years from there.

Why it matters

The crime gave Lanka Sigiriya, now a World Heritage Site, and set up the war of 495 that ended Kassapa’s reign.
