Tyrrhenus Or Tyrsenus
A son of the Lydian king Atys and Callithea, and a brother of Lydus, is said to have led a Pelasgian colony from Lydia into Italy, into the country of the Umbrians, and to have given to the colonists his name, Tyrrhenians. (Herodotus iv. 94; Dionys. Hal. i. 27.)
Others call Tyrrhenus a son of Heracles by Omphale (Dionys. i. 28), or of Telephus and Hiera, and a brother of Tarchon. (Tzetzes on Lycophron 1242, 1249.) The name Tarchon seems to be only another form for Tyrrhenus, and the two names represent a Pelasgian hero founding settlements in the north of Italy.
From Smith's Dictionary of Greek and Roman Biography and Mythology From Pharsalia By LucanTyrrhenus high
Upon the bulwarks of his ship was struck
By leaden bolt from Balearic sling
Of Lygdamus; straight through his temples passed
The fated missile; and in streams of blood
Forced from their seats his trembling eyeballs fell.
From The Aeneid by Virgil. Book XI
Tyrrhenus, and Aconteus, void of fear, By mettled coursers borne in full career, Meet first oppos'd; and, with a mighty shock, Their horses' heads against each other knock. Far from his steed is fierce Aconteus cast, As with an engine's force, or lightning's blast: He rolls along in blood, and breathes his last. The Latin squadrons take a sudden fright, And sling their shields behind, to save their backs in flight
