Nice Work was mistaken when it claimed in its post of January 9th 2008, Duke of Berry, Mrs. Potiphar & 2 Frinks, (in a mouseover text) that the Duke of Berry’s first name was Franken.
It was not.
The Christian name of the 14th-15th century French Duke, who happens to have been the brother of the French King, Charles V, was, in fact, John.
So far as the fact-checking department of Nice Work has been able to ascertain, there never existed a Franken, Duke of Berry.
Nice Work regets the error.
