practised by the Scotti ("the scarred and painted men"?), and the
Britons dyed themselves with woad, while what seem to be tattoo marks
appear on faces on Gaulish coins.[42] Tattooing, painting, and
scarifying the body are varieties of one general custom, and little
stress can be laid on Pictish tattooing as indicating a racial
difference. Its purpose may have been ornamental, or possibly to impart
an aspect of fierceness, or the figures may have been totem marks, as
they are elsewhere. Finally, the description of the Caledonii, a Pictish
people, possessing flaming hair and mighty limbs, shows that they
differed from the short, dark pre-Celtic folk.[43]

The Pictish problem must remain obscure, a welcome puzzle to
antiquaries, philologists, and ethnologists. Our knowledge of Pictish
religion is too scanty for the interpretation of Celtic religion to be
affected by it. But we know that the Picts offered sacrifice before
war--a Celtic custom, and had Druids, as also had the Celts.

The earliest Celtic "kingdom" was in the region between the upper waters
of the Rhine, the Elbe, and the Danube, where probably in Neolithic
times the formation of their Celtic speech as a distinctive language
began. Here they first became known to the Greeks, probably as a
semi-mythical people, the Hyperboreans--the folk dwelling beyond the
Ripoean mountains whence Boreas blew--with whom Hecataeus in the fourth
century identifies them. But they were now known as Celts, and their
territory as Celtica, while "Galatas" was used as a synonym of "Celtae,"
in the third century B.C.[44] The name generally applied by the Romans
to the Celts was "Galli" a term finally confined by them to the people
of Gaul.[45] Successive bands of Celts went forth from this
comparatively restricted territory, until the Celtic "empire" for some
centuries before 300 B.C. included the British Isles, parts of the
Iberian peninsula, Gaul, North Italy, Belgium, Holland, great part of
Germany, and Austria. When the German tribes revolted, Celtic bands
appeared in Asia Minor, and remained there as the Galatian Celts.
Archaeological discoveries with a Celtic _facies_ have been made in most
of these lands but even more striking is the witness of place-names.
Celtic _dunon_, a fort or castle (the Gaelic _dun_), is found in
compound names from Ireland to Southern Russia. _Magos_, "a field," is
met with in Britain, France, Switzerland, Prussia, Italy, and Austria.
