Greek namen, from (πολύ) [poli] + (ξενία) [ksenos] = "very hospitable"
In Greek mythology, Polyxena was the youngest daughter of king Priam of Troy and his queen, Hecuba. She is considered the Trojan version of Iphigenia, daughter of Agamemnon and Clytemnestra. Polyxena is not in Homer's "Iliad", appearing in works by later poets, perhaps to add romance to Homer's austere tale. An oracle prophesied that Troy would not be defeated if Polyxena's brother, Prince Troilus, reached the age of twenty. During the Trojan War, Polyxena and Troilus were ambushed when they were attempting to fetch water from a fountain, and Troilus was killed by the Greek warrior Achilles, who soon became interested in the quiet sagacity of Polyxena.
Achilles, still recovering from Patroclus' death, found Polyxena's words a comfort and was later told to go to the temple of Apollo to meet her after her devotions. Achilles seemed to trust Polyxena-he told her of his only vulnerability: his vulnerable heel. It was later in the temple of Apollo that Polyxena's brothers, Paris and Deiphobus, ambushed Achilles and shot him in the heel with an arrow, supposedly guided by the hand of Apollo himself, steeped in poison.
