Very short article so may look for accompanying articles after...
This (https://www.cambridge.org/core/journals/antiquity/article/buckquoy-orkney-addressing-the-pictishviking-transition-in-northern-scotland/7D385A829027ED1D810828861E05994F) is the originating source article from Antiquity (the journal, not the vague historical period ;) ).
The lead author is the same Gordon Noble who wrote the Picts book I read recently, and have reviewed for Slingshot.
Thank you kindly sir. Much obliged :)
