The Story of the Friend at the Inn, from Cicero

In this episode, two friends on a long journey argue over whether or not they should spend the night at a rather grim and unpleasant taverna... This Greco-Roman folktale was 'very well known' according to Cicero, and features some familiar tropes, including dreams, vengeance and danger on the road; the story has been adapted from Cicero, On Divination, 1.57 and Valerius Maximus, Memorable Deeds and Sayings, 1.7.ext.10.
