and
from Gaul or Spain, as some did, Britain was more easily reached than
Ireland by migrating Goidels from the Continent. Prominent Goidelic
place-names would become Brythonic, but insignificant places would
retain their Goidelic form, and to these we must look for decisive
evidence.[35] A Goidelic occupation by the ninth century B.C. is
suggested by the name "Cassiterides" (a word of the _q_ group) applied
to Britain. If the Goidels occupied Britain first, they may have called
their land _Qretanis_ or _Qritanis_, which Pictish invaders would change
to _Pretanis_, found in Welsh "Ynys Pridain," Pridain's Isle, or Isle of
the Picts, "pointing to the original underlying the Greek [Greek:
Pretanikai Nesoi] or Pictish Isles,"[36] though the change may be due to
continental _p_ Celts trading with _q_ Celts in Britain. With the
Pictish occupation would agree the fact that Irish Goidels called the
Picts who came to Ireland _Cruithne=Qritani=Pre-tani_. In Ireland they
almost certainly adopted Goidelic speech.

Whether or not all the Pictish invaders of Britain were called
"Pictavi," this word or Picti, perhaps from _quicto_ (Irish _cicht_,
"engraver"),[37] became a general name for this people. _Q_ had been
changed into _p_ on the Continent; hence "Pictavi" or "Pictones," "the
tattooed men," those who "engraved" figures on their bodies, as the
Picts certainly did. Dispossessed and driven north by incoming Brythons
and Belgae, they later became the virulent enemies of Rome. In 306
Eumenius describes all the northern tribes as "Caledonii and other
Picts," while some of the tribes mentioned by Ptolemy have Brythonic
names or names with Gaulish cognates. Place-names in the Pictish area,
personal names in the Pictish chronicle, and Pictish names like
"Peanfahel,"[38] have Brythonic affinities. If the Picts spoke a
Brythonic dialect, S. Columba's need of an interpreter when preaching to
them would be explained.[39] Later the Picts were conquered by Irish
Goidels, the Scotti. The Picts, however, must already have mingled with
aboriginal peoples and with Goidels, if these were already in Britain,
and they may have adopted their supposed non-Aryan customs from the
aborigines. On the other hand, the matriarchate seems at one time to
have been Celtic, and it may have been no more than a conservative
survival in the Pictish royal house, as it was elsewhere.[40] Britons,
as well as Caledonii, had wives in common.[41] As to tattooing, it wa
