And while on all these lines of investigation we have traced the manifestations of these early forms of culture and civilisation up to points at which they seem to touch the culture and civilisation of the Roman Empire, it is to be observed that they do no more than touch it—they are not merged in it. In all their distinctive features they are still Celtic, and Celtic exclusively. There is nothing Roman in the forms of the prevailing types; there is nothing Roman in the art that decorates these forms; there is nothing Roman in the typical character of the structures in which they are found. The forms, the art, and the architecture are those of Scotland’s Iron Age—the Pagan Period of her Celtic people.
