Nalacharitham is a Kathakali play (Aattakatha) written by Unnayi Warrier. Based on the Mahabharatha, it tells the story of King Nalan and his consort Damayanthi. The play consists of four parts – called First, Second, Third and Fourth Day – each part being long enough to be performed over a full night. The source of the story is the tale of Nalan and Damayanthi as told in the Mahabharatha . In the 18th century, Unnayi Warrier structured the contents of this story as Nalacharitham Attakatha to suit the art-form Kathakali. Nalacharitham is a considered the most romantic work of art constructed on the classical basement of Kathakali, which has earned it the epithet of being the Shakuntalam of Malayalam literature.
Story line: Sage Naradan tells Nalan about Damayanthi and the need to marry her. Hamsam acts as the messenger to Damayanthi and fills her mind with love for Nalan.
Sage Naradan reaches Nalan's kingdom Nishadha. King Nalan receives him and asks him what he wanted the King to do. He tells Nalan that in Kundinapuri, there is a beautiful damsel named Damayanthi who is sought after even by gods and he should marry her. Nala wonders what right he, as human being, had to contest with the gods to marry her. But Naradan assures him that as the Ruler of the country, he only had the right and might to marry her and he should endeavour to do it. The Sage wishes him all success and takes leave.
Then, Nalan indulges in thoughts about the beauty of Damayanthi. He visualises her in all splendor in every part of her body and comes to the conclusion that he will have no peace of mind until he marries her. He is so astounded by the lascivious charm of Damayanthi that he entrusts his duties as the King to his Minister and goes to the royal garden to find some peace of mind.
In the royal garden, Nalan, aroused by the description of the beauty of Damayanthi, is further disconcerted by the breeze carrying the perfumes of flowers, the trees embraced by flowering jasmine plants, the dancing peacocks and the sound of sweet-singing birds. He seesthree swans of different colours on the banks of the pond nearby, of which a golden one engrosses his attention immensely.
