From the article:

Sir Walter Scott took the plot of his Bride of Lammermoor from this incident, but he disclaimed any intention of making Lord Stair the basis for Sir William Ashton.

Jack, I agree that the photo you linked to is a more appropriate depiction of the period being portrayed, and is the way I have usually seen the production. But—you're going to have to explain to me why the wearing of kilts by some of the cast members in some productions of Lucia do Lammermoor offensive to Scots.

It's a work of FICTION, Jack!

And Un Ballo in Maschera, once again, although the idea for the plot of the play from which Verdi got his idea for the opera was derived from an actual incident, in the opera itself, the assassination plot was hatched up by Count Anckarström, who is under the impression that the King and his wife, Amelia, are having an affair.

Again, A WORK OF FICTION.

What does today's political climate have to do with it?
