What is "rudrata"

Rudrata (, ) was a Kashmiri poet and literary theorist, who wrote a work called the Kavyalankara in the first quarter of the ninth century. Very little is known about Rudrata. From Namisadhu's commentary on the verses 12-14 of the fifth chapter of the Kavyalankara, it is inferred that he was also known as Shatananda and his father's name was Bhamuka.
