Pliny

Celts form the fourth Aryan race. It is very difficult to determine the origin of it, since it is a part of the early Aryan race that had remained uncontaminated in the centre of Europe.

The Celts gave rise to the Greeks, Macedonians and Carthaginians; these peoples were beautiful, strong, warlike, versatile and lovers of Nature. The origin of the Romans is very obscure because the Etruscans, ancient remnants of the Iranians, and the Sabinians, inhabitants of the Latium, were of Aryan-Semite origin; but in Sicily and throughout the coast of Calabria Italic people lived, of pure Celtic race, who eventually make their lands thrive and, mixed with other peoples, founded the Roman caste.
