" [describing the Mahavamsa, 6th-century chronicle of Sri Lanka]

The king Yasalakatissa, who had come to his title by killing his older brother during a watersports festival, had a gatekeeper named Subha. Subha was the spitting image of the king, and so Tasalakatissa draped Subha in royal regalia and seated him on the throne. Whole the courtiers clustered around the impostor and sang his praises, Yasalakatissa, having dressed as a gatekeeper and stationed himself at the door, shook with laughter at the ingenuity of his jape.

Then one day Subha addressed the ministers while the king was laughing, 'Why does this gatekeeper laugh in my presence?'
He had King Yasalakatissa killed. Subha then reigned six years. Even when the truth was later discovered, he retained his throne and became known as King Subha. "
