Dīpavaṃsa

Starting with the Dīpavaṃsa in the 4th century, the Theravādins of the Mahāvihāra in Sri Lanka attempted to identify themselves with the original Sthavira sect of India.

The Dīpavaṃsa lauds the Theravāda as a "great banyan tree," and dismissively portrays the other early Buddhist schools as thorns (kaṇṭaka).

In the meantime, Sinha-bahu and Sinhasivali, as king and queen of the kingdom of Lala (Lata), "gave birth to twin sons, sixteen times."

But the king caused him and his seven hundred followers to leave the kingdom, and they landed in Sri Lanka, at a place called Tamba-panni, on the exact day when the Buddha passed into Maha Parinibbana.
