CAMPEYYA-JATAKA.
"Who is it like," etc.--This story the Master told while dwelling in Jetavana, about the fast-day vows. The Master said, "It is well done, lay Brethren, that ye have taken upon you the fast-day vows. Wise men of old likewise even renounced the glory of being a Serpent King, and lived under these vows." Then at their request he told a story of the past.
Once upon a time, when Anga was king in the kingdom of Anga, and Magadha king in Magadha, betwixt the realms of Anga and Magadha was a river Campa, where was a place where serpents dwelt, and here a serpent king Campeyya held sway.
Sometimes King Magadha took the Anga country, sometimes King Anga took Magadha. One day King Magadha, having fought a battle with Anga and got the worse, mounted his charger and took to flight, pursued by Anga's warriors. When he came to the Campa river, it was in flood. But he said, "Better death drowned in this river than death at the hands of my enemies!" Then man and horse plunged in the stream.
Now the serpent king Campeyya had built him under the water a jewelled pavilion; and there at this moment in the midst of his court he was carousing deep. But the king and his horse plunged into the river just in front of the Serpent King. The serpent, beholding this magnificent monarch, conceived a liking for him. Rising from his seat, he made the king sit down upon his own throne, bidding him fear nought, and asked why he came plunging into the water. The king told him all as it was. Then said the serpent, "Fear nothing, O great king! I will make you master of both kingdoms." Thus he consoled him, and for seven days he showed him high honour. On the seventh day he with King Magadha left the serpent palace. Then by the Serpent King's power, King Magadha got possession of King Anga, and slew him, and ruled over the two realms together. From that time there was firm affiance between him and the Serpent King. [455] Year by year he caused a jewelled pavilion to be built on the bank of the river Campa, and offered tribute to the Serpent King at great cost: the Serpent King would come forth with a large retinue from his palace to receive the tribute, and all the people beheld the glory of the Serpent King.
