Of course parts of the continent have to be called places that
were 'once' Celtic, places such as Austria and the Czech Republic, and of
course things Celtic survived in Gaul long after the Roman conquest -
Sidonius Appolinaris refers to the 'Celtic language' in the fifth century
AD! But to take from this that the 12th Century Norman-French were
culturally indebted to the Celts enough for them to be the first to give
us notice of a 'genuine' Celtic figure is overstepping the bounds of
evidence just a little. Frankly I really don't see why the celticity of a
figure such as Lancelot need be defended so staunchly, its not as if
there is a shortage of real Celtic heroes.
