On the fall of Troy, Menelaus smote Deiphobus in the belly, and poured forth his liver and guts.
Papilio deiphobus was created in 1758.
Athena disguised herself as Deiphobus in order to deceive Hector.
See below to link of Priam's children, incuding Deiphobus.
Menelaus
Deiphobus, horribly mutilated during the sack of Troy, appears to Aeneas in the Underworld. He tells him the story of his death, which entails Helen's betrayal in signaling Menelaus to Deiphobus's bedchamber. He was mutilated in the sack of Troy. While with Aeneas, he begs the gods for revenge against the Greeks.
Dēiphobus, in Greek myth, son of Priamhttp://www.answers.com/topic/priam, king of Troy, and of Hecuba. He took a prominent part in the fighting at Troy. After the death of Paris he married Helen and was subsequently killed at the fall of Troy. His body disappeared, but Aeneas erected a cenotaph to him on Cape Rhoeteum; on his visit to the Underworld Aeneas heard the story of his death from Deiphobus himself (see http://www.answers.com/topic/aeneid%29.
Athena changed herself into Hector's brother, Deiphobus.
Yes Helen was married to Menelaus and married also to Prince Paris of Troy and after his death to Deiphobus his brother, both sons of Priam King of Troy. After Deiphobus died at Menelaus's hands, he took back Helen as his wife as he had intended from the start of the Trojan war.
Achilles was not the lover of Helen during Troy (there is a myth that after death they became immortals on the White Isle and married), her husbands were Menelaus, Paris and Deiphobus
Helene Queen of Sparta, also called Helene of Troy for her marriage to Prince Paris and Prince Deiphobus, sons of Priam King of Troy.
The brothers of Hector in Greek myth (and one must assume the movie Helen of Troy as well) are Troilus, Paris, Aesacus, Deiphobus, Helenus, and the youngest Polydorus- but Priam is said to have had been the father of fifty sons and many daughters. See link.
Yes, Paris of the Trojan War had brothers and sisters. He was a son of King Priam and Queen Hecuba of Troy, and his siblings included Hector, Deiphobus, Helenus, Cassandra, and Polyxena, among others.
