Witches in Scotland? Methinks I’ve heard that somewhere before…

What are these,
So wither’d and so wild in their attire,
That look not like th’ inhabitants o’ th’ earth,
And yet are on’t? Live you? or are you aught
That man may question? . . .
Macbeth (1.3.39-41).

First,  religion was interwoven with the land and the people. Winter Solstice was a time to celebrate a return to light from the frosty dark of winter.
Then, there were killings prompted by greed and a surge of Christianity.
Now, we see a resurgence of pagans in Scotland.
