The word Celt was used to describe both the whole family (including Brythons and Goidels), and also the special branch of the family to which Caesar applied the term. It is as if the word "Teutonic" had been used to describe the whole Aryan Family, and had been specially employed in speaking of the Romance peoples. The word "Celtic" has, however, become a technical term as opposed to "Saxon" or "English", and it is impossible to avoid its use. Besides the Goidels, or so-called Celts, and the Brythonic Celts or Britons, we find traces in Scotland of an earlier race who are known as "Picts", a few fragments of whose language survive. About the identity of these Picts another controversy has been waged. Some look upon the Pictish tongue as closely allied to Scottish Gaelic; others regard it as Brythonic rather than Goidelic; and Dr. Rhys surmises that it is really an older form of speech, neither Goidelic nor Brythonic, and probably not allied to either, although, in the form in which its fragments have come down to us, it has been deeply affected by Brythonic forms. Be all this as it may, it is important for us to remember that, at the dawn of history, modern Scotland was populated entirely by people now known as "Celts", of whom the Brythonic portion were the later to appear, driving the Goidels into the more mountainous districts. The Picts, whatever their origin, had become practically amalgamated with the "Celts", and the Roman historians do not distinguish between different kinds of northern barbarians.
