In the post-feast portion of this fragmentary text, Eumolpus (Mr. Good Singer) replaces Ascyltus as Encolpius' rival for Giton's affections. Like Petronius, Eumolpus is a writer. When Encolpius first meets him in the art gallery (c. 8), he says that his appearance suggests that he was a man of letters with an "indefinable aura of greatness." Encolpius expects great things from this man who proclaims to be a genius and complains about the contemptible morals of his fellow Romans. Describe how Eumolpus' appearance deceives Encolpius. Give 3 examples that truly display his character.
