Eunoe is a feature of Dante's Divine Comedy created by Dante as the fifth river of the dead. In the Purgatorio, the second cantica of Dante's poem, penitents reaching the Garden of Eden at the top of Mount Purgatory are first washed in the waters of the river Lethe in order to forget the memories of their mortal sins. They then pass through Eunoe to have the memories of their good deeds in life strengthened.
