Sorry! My blunder!
The Celts Alphabet
here
The ancient Celts had a form of writing called ogham (pronounced OH-yam). It was the writing of Druids and Bards. Ogham is also called 'Tree Alphabet' because each letter corresponds to a tree and an associated meaning. The letters were, in fact, engraved onto sticks as well as larger standing stones.
There is surmise that the Pict's alphabet evolved more early then other Europe's alphabets.
Pictland, was made up of a large area of what is now modern day Scotland, mainly in the low-lying coastal areas of Eastern Scotland where they sustained themselves through fishing and farming. The Picts weren't any one particular race or culture per se, but a military alliance which was formed around 100 AD to defend against the Roman invaders. The name Pict itself is believed to be derived from the Latin word Picti, "painted men". In fact, the Pictish nation out-lasted the would-be conquerors and predated the formal organization of both the Scots and Irish. Historical and archaeological records also show that they were also quite fierce warriors, judging by accounts of those whom they defeated in battle. They were the dominant military power in that area for almost 500 years.
As regards the Pict's origin they were native people of Britain and hadn't any relations to Germanics. This were the nation which lived in all territory of Europe until the Celt's migration began and replaced the Pict's tribes to West.
