Bodhi Vamsa is a medieval Pali prose-poem or religious chronicle from Sri Lanka that tells the story of the Bodhi tree, the sacred fig tree linked to the Buddha's enlightenment. Because it is a specific historical work rather than a general poetic form, the term usually refers to that text itself, not to a broad class of poems.
A prose poem in elaborate Sanskritized Pali, composed by Upatissa in the reign of Mahinda IV. of Ceylon about a.d. 980. It is an adaptation of a previously existing work in Sinhalese on the same subject, and describes the bringing of a branch of the celebrated Bo or Bodhi tree (i.e. Wisdom Tree, under which the Buddha had attained wisdom) to Ceylon in the 3rd century b.c. The Bodhi Vamsa quotes verses from the Mahavamsa, but draws a great deal of its material from other sources; and it has occasionally preserved details of the older tradition not found in any other sources known to us.
Example
A Bodhi Vamsa passage might describe the sacred branch arriving in Ceylon, with the king watching as the people bow and the river winds silver around the shore.
