The roots of Helvetia

The name *Helvetia* derives from the Celtic Helvetii, who lived in the area of present-day Switzerland. But the date in the source item is wrong: known written references to the Helvetii are chiefly from the 1st century BCE, including Julius Caesar’s account of events in 58 BCE—not the 5th century BCE. Today *Confoederatio Helvetica* is the Swiss Confederation’s official Latin name, and the country code CH comes from it. [1–3]
