The legend is given its most vivid and detailed treatment in the Roman poet Virgil's epic, the Aeneid (published around AD 20). According to this, the Latin tribe's first king was Latinus, who gave his name to the tribe and founded the first capital of the Latins, Laurentum, whose exact location is uncertain. The Trojan hero Aeneas and his men fled by sea after the capture and sack of their city, Troy, by the Greeks in 1184 BC, according to one ancient calculation. After many adventures, Aeneas and his Trojan army landed on the coast of Latium near the mouth of the Tiber. Initially, King Latinus attempted to drive them out, but he was defeated in battle. Later, he accepted Aeneas as an ally and eventually allowed him to marry his daughter, Lavinia. Aeneas supposedly founded the city of Lavinium (Pratica di Mare, Pomezia), named after his wife, on the coast not far from Laurentum. It became the Latin capital after Latinus' death. Aeneas' son (by his previous Trojan wife, a daughter of king Priam of Troy), Ascanius, founded a new city, Alba Longa in the Alban Hills, which replaced Lavinium as capital city. Alba Longa supposedly remained the Latin capital for some 400 years under Aeneas' successors, the Latin kings of Alba, until his descendant (supposedly in direct line after 15 generations) Romulus founded Rome in 753 BC. Under a later king Tullus Hostilius (traditional reign-dates 673-642 BC), the Romans razed Alba Longa to the ground and resettled its inhabitants on the mons Caelius (Caelian Hill) in Rome.
