Ancient Romans are originally from Greeks

According to Dionysius of Halicarnassus, many Roman historians (including Porcius Cato and Gaius Sempronius) regarded the origins of the Romans (descendants of the Aborigines) as Greek despite the fact that their knowledge was derived from Greek legendary accounts.^[2] The Sabines, specifically, were first mentioned in Dionysius's account for having captured by surprise the city of Lista, which was regarded as the mother-city of the Aborigines.^[3] Ancient historians were still debating the specific origins of the Sabines. Zenodotus of Troezen claimed that the Sabines were originally Umbrians that changed their name after being driven from the Reatine territory by the Pelasgians. However, Porcius Cato argued that the Sabines were a populace named after Sabus, the son of Sancus (a divinity of the area sometimes called Jupiter Fidius).^[4] In another account mentioned in Dionysius's work, a group of Lacedaemonians fled Sparta since they regarded the laws of Lycurgus as too severe. In Italy, they founded the Spartan colony of Foronia (near the Pomentine plains) and some from that colony settled among the Sabines. According to the account, the Sabine habits of belligerence (aggressive or warlike behavior) and frugality (prudence in avoiding waste) were known to have derived from the Spartans.^[5] Plutarch also states in the Life of Numa Pompilius, "Sabines, who declare themselves to be a colony of the Lacedaemonians..."
