so do you have any opinion as to what language group pictish is?

there were celtiberian scripts, but the few i've seen do not
obviously resemble ogham. ogham appears to be based on the needs of
gaelic, but i don't think it's latin based. this is probably why
later gaelic writing in the latin alphabet gave different values to
latin letters. (i actually speak a bit of almost extinct nova scotian
gaelic--lochaber and barra dialects--but it isn't much use in
toronto, so i'm getting worse every year)

the gaelic use of the alphabet gives letters different values
depending on where they are found in the word or in relation to the
heighnouring words. i have assumed that this is a remenant of ogham
and of early irish, but it could just as easily be the creation of
late medieval monks.

so what about scythian. is there any surviving written scythian?
