History of Scotland
Pinkerton next collected and printed in 1789 certain "Vitae sanctorum scotiae", and, a little later, published his "Enquiry into the History of Scotland preceding the Reign of Malcolm III". His assertion that the Celts were incapable of assimilating the highest forms of civilisation excited "violent disgust", but the Enquiry was twice reprinted, in 1794 and 1814, and is still of value for the documents embodied in it.
