Hadrian wrote poetry in both Latin and Greek; one of the few surviving examples is a Latin poem he reportedly composed on his deathbed (see below). Some of his Greek productions found their way into the Palatine Anthology. He also wrote an autobiography, which "Historia Augusta" says was published under the name of Hadrian's freedman Phlegon of Tralles. It was not, apparently, a work of great length or revelation, but designed to scotch various rumours or explain Hadrian's most controversial actions. It is possible that this autobiography had the form of a series of open letters to Antoninus Pius.
