Pliny the Elder, a Roman writer, documented the earliest account pertaining to the inhabitants of the peninsula around the mid-first century AD, referring to them as the Catharrei, a designation which may have derived from the name of a prominent local settlement. A century later, Ptolemy produced the first known map to depict the peninsula, referring to it as Catara. The map also referenced a town named “Cadara” to the east of the peninsula.
