The Tyrrhenians, or Tyrsenians , were exonyms used by authors of Ancient Greek to refer to a non-Greek people. While ancient sources have been interpreted in a variety of ways, one theory identifies the Tyrsenians with the Etruscan, Raeti, and Lemnian cultures, whose languages have been grouped together as the Tyrsenian languages, based on strong similarities in their written languages.
Earliest references
The origin of the name is uncertain and is known to be used only by Greek authors although it is apparently not of Greek origin. It has been connected to tursis, also a "Mediterranean" loan into Greek, meaning "tower". Direct connections with Tusci, the Latin exonym for the Etruscans, from Turs-ci, have also been attempted. See also Turan, tyrant. The earliest instances in literature are in Hesiod and the Homeric hymn to Dionysus. Hesiod has The Homeric hymn to Dionysus has Tyrsenian pirates seizing Dionysus:
Possible identification with Etruscans
In the 6th and 5th centuries BC, the name referred specifically to the Etruscans for whom the Tyrrhenian Sea is named, according to Strabo. In Pindar, the Tyrsanoi appear grouped with the Carthaginians as a threat to Magna Graecia: The name is also attested in a fragment by Sophocles. The name becomes increasingly associated with the generic Pelasgians. Herodotus places them in Crestonia in Thrace, as neighbours of the Pelasgians. Similarly, Thucydides mentions them together with the Pelasgians and associates them with Lemnian pirates and with the pre-Greek population of Attica. Lemnos remained relatively free of Greek influence until Hellenistic times, and the Lemnos stele of the 6th century BC was inscribed with a language very similar to Etruscan, which has led to the postulation of a Tyrrhenian language family of Etruscan, Lemnian and Raetic. There is thus evidence that there was indeed at least a linguistic relationship between the Lemnians and the Etruscans. The circumstances of this are disputed; most scholars would ascribe Aegean Tyrrhenians to the Etruscan expansion from the 8th to the 6th centuries, putting the homeland of the Etruscans in Italy and the Alps, particularly because of their relation to the Alpine Raetic population. Another hypothesis connecting the Tyrrhenians and the Etruscans posits that the Etruscans derive at least partially from a 12th century BC invasion from the Aegean and Anatolia imposing itself over the Italic Villanovan culture, with some scholars claiming a relationship or at least evidence of close contact between the Anatolian languages and the Etruscan language. There is no archaeological evidence from material culture of such a cultural shift, but adherents of the latter school of thought point to the legend of Lydian origin of the Etruscans referred to by Herodotus and Livy's statement that the Raetians were Etruscans driven into the mountains by the invading Gauls. Critics of the theory point to the very scanty evidence of a linguistic relationship of Etruscan with Anatolian and to Dionysius of Halicarnassus, who decidedly argues against an Etruscan-Lydian relationship.
Identification with ''Spard''
Spard, or Sard, another name closely connected to the name Tyrrhenian, was the capital city of the land of Lydia, the original home of the Tyrrhenians, anf was referred to by the Greeks as "Sardis". The name preserved by Greek and Egyptian renderings is "Sard" since the Greeks called it Sardis, and the name appears in the Egyptian inscriptions as Srdn.
It has been hypothesised that the Teresh, who appear among other Sea Peoples in a number of Ancient Egyptian inscriptions from 1200 to 1150 BC, may be the same people as the Tyrsenians.
