Irish Kilt?

[SeumasA]

One of the newer books on this subject is Tim Clarkson's "The Makers of Scotland: Picts, Romans, Gaels and Vikings". He covers this question in detail.

This was a popular view from the 1760's to the 1960's where the main source of this was Bede retelling Geoffrey of Monmouth. There was no real evidence to support this. Even as far back as 1845 historians such as J. M. Lappenberg were publishing books saying it was all nonsense. Even if you refer to where Geoffrey took his info from, the Irish Annals of Tigernach, it states Feargus Mor mac Earca cum gente Dal Riada partem Britaniae tenuit, et ibi mortuus est, (Fergus Mór mac Eirc, with the people of Dál Riata, held part of Britain, and he died there.) This section of the Annals appears to have been written about 500 to 600 years after this supposed event, it's not part of the original document and it's been made doubtful that such names existed in their written forms at that earlier time.
But, regardless of it being a forgery or not, note it doesn't mention Scotland, only Britain.
A more modern view of what is being taught in Scotland today can be found summarised fairly well here. http://www.electricscotland.com/hist...scotsirish.htm
No invasion from the Gaelic Irish, no Irish settlers, just a group of different peoples living in the extreme North West of Europe but with similar languages, customs and cultures.

What I briefly remember about that period from the survey course 'Scottish History 1' (c. 800 CE to 1707 CE) at Glasgow University was that the evidence pointed to two way traffic in trade, human migration and cultural cross-pollination between the north-east of Ireland (primarily Antrim, but even as far west as Donegal) and the western sea board of Scotland especially from Galloway to Argyll, and from much earlier than the formation of Dal Riata.
