Ripheus
Ripheus (also Rifeo and Rupheo) was a Trojan hero and the name of a figure from the Aeneid of Virgil. A comrade of Aeneas, he was a Trojan who was killed defending his city against the Greeks. "Ripheus also fell," Virgil writes, "uniquely the most just of all the Trojans, the most faithful preserver of equity; but the gods decided otherwise" (Virgil, Aeneid II, 532-3). Ripheus's righteousness was not rewarded by the gods.
Ripheus in later works
Dante
In Paradiso Canto XX:73-148, St. Thomas Aquinas suggests that the virtuous pagan will receive either inspiration or an instructor from God to achieve his conversion. In his Divine Comedy, Dante placed Ripheus in Paradisio, in the sixth sphere of Jupiter (Paradiso Canto XX:1-72), the realm of those who personified justice (Cantos 18 through 20).
Boccaccio
In Boccaccio's Il Filostrato (1333-1339), Ripheus is named as one of the Trojans taken prisoner by the Greeks (IV.3.).
Chaucer
Il Filostrato served as the basis for Chaucer's Troilus and Criseyde. In it, Ripheo is mentioned as being unable to prevent Antenor from being taken prisoner (Tr IV.50-56). As Rupheo, he appears once, in final rhyming position (Tr IV.53).
