Greek writers started associating the name "Tyrrhenians" with the "Pelasgians"

It was only in the 5th century BC, when the Etruscan civilization had been established for several centuries, that Greek writers started associating the name "Tyrrhenians" with the "Pelasgians", and even then, some did so in a way that suggests they were meant only as generic, descriptive labels for "non-Greek" and "indigenous ancestors of Greeks".
