"Phlegon, who was a collector of stories"

Phlegon of Tralles was one of Hadrian's freedmen, whose work "On Marvels" does include a collection of ghost stories. One of these, "The Bride of Corinth," considered by some to be among the world's first vampire stories, was later adapted as a poem by Goethe. An English translation of both Goethe's poem and Phlegon's original is available at:

It tells the story of a young man tricked into a sexual union with the spirit of a dead girl.
