At present philologists do not seem able to speak with certainty on this point.

But the evidence for some amount of invasion seems adequate.] All this must have contributed to the reintroduction of Celtic national feeling and culture.

A Celtic immigrant, it may be, was the man who set up the Ogam pillar at Silchester (Fig.

21), which was discovered in the excavations of 1893.[1] The circumstances of the discovery show that this pillar belongs to the very latest period in the history of Calleva.
Its inscription is Goidelic: that is, it does not belong to the ordinary Callevan population, which was presumably Brythonic.

It may be best explained as the work of some western Celt who reached Silchester before its British citizens abandoned it in despair.
