The Digenis Akritas (also known as the "Romance of Digenis Akritas") is an epic poem that is believed to have been written in the 10th to 11th centuries AD. However, the author is unknown and there is no evidence of an author named "Digenis Andreas Homatenos" existing.
The poem is considered one of the most important works of Byzantine literature and has been attributed to a variety of authors over the years. Some scholars believe that it may have been written by a group of people over a period of time.
