He fought alongside his half-brother, Ajax, in the Trojan War and is the legendary founder of the city of Salamis on Cyprus.
Through his mother, Teucer was the nephew of King Priam of Troy and the cousin of Hector and Paris—all of whom he fought against in the Trojan War.
In total, Teucer slew thirty Trojans during the war;[4] of those Homer mentions Aretaon, Orsilochus, Ormenus, Ophelestes, Daetor, Chromius, Lycophontes, Amopaon, Melanippus, Prothoon and Periphetes,[5] as well as the aforementioned Archeptolemus.
[6] After Ajax's suicide, Teucer guarded the body to make sure it was buried, insulting Menelaus and Agamemnon when they tried to stop the burial.
He was disowned by his father, wasn't allowed back on Salamis Island, and set out to find a new home.
