Mathaios Monselas, 58, lived in a cave near the Prison of Socrates on the Filopappos Hill, but left because of the rats. Now he is living out of a tent. He’s well-known in Greece for serving 12 years in prison for murder with the victim’s consent. He said: “In a cave you’re sheltered from the cold. It’s better than living on a bench or on the street, but it’s still a miserable side of life.”
