DEIPHEBE, DEIPHEBUS was the third son of Priam and Hecuba of Troy. He married Helen after Paris's death (Heroides XVI, 361-362; Aeneid VI.500-534; Ephemeridos belli Troiani I.10, IV.22, V.12).
The Dreamer sees Deiphebus in hell, HF I.444. Virgil says that Aeneas meets Deiphebus in the underworld, and Deiphebus tells the story of his betrayal by Helen, whom he married after Paris's death, and how he died when Odysseus and his companions came out of the Trojan horse. In Troilus and Criseyde, Deiphebus is Troilus's favorite brother. (Boccaccio describes briefly the affection between Troilo and Deifebo in Il Filostrato vii.77-83.) Pandarus arranges a rendezvous between Troilus and Criseyde at Deiphebus's house, where Troilus pretends to be ill, and Criseyde visits him there. Helen and Deiphebus also visit him; then they go down together into the garden to read a letter from Hector, Tr II.1394-1750. When they return, Troilus groans loudly, Tr III.204-207; then Helen and Deiphebus leave him, Tr III.218-226. [Creseyde: Eleyne2: Pandar: Troilus]
