Came across an essay on him by Mysore Hiriyanna that sheds some light on his masterpiece - "Uttara Rama Charita"
How does it differ from Uttara Kanda in Valmiki Ramayana on which it is based
He belongs to the early part of 8th century - a native of Vidarbha, who nevertheless spent most of his career in the court of the Kannauj king Yashovarman = who was a successor to Harsha, though not related to him
He is best known for his two Ramayana based plays - Mahaviracharita (deals with Rama's early life) and Uttara Rama Charita (based on Uttara Kandam)
Hiriyanna's essay outlines the differences b/w this play and Valmiki's Uttara Kandam, which probably precedes this play by nearly a thousand years
1. In the Epic, Sita prays to Mother Earth to relieve her of her misery. The Earth opens up and she disappears
Perhaps the playwright was particular about a happier ending for his audience than the epic afforded
In the play, SIta throws herself into Ganga, but gives birth to kids thanks to the intervention of Ganga and Bhumi, who entrust the kids to Valmiki
In the play, nobody is aware of her whereabouts, which adds to the audience's appreciation of her pathos
In the play, Rama bursts into tears more than once, as per Hiriyanna, revealing his human side
