Eugammon of Cyrene in Wikipedia
Eugammon of Cyrene was an early Greek poet to whom the epic Telegony was ascribed. According to Clement of Alexandria, he stole the poem from the legendary early poet Musaeus; meaning, possibly, that a version of a long-existing traditional epic was written down by Eugammon. He is said to have flourished 567/6 BC.
