Robertvs

Was in Edinburgh for lunch and popped into the National Portrait Gallery.
This is a plaster replica of Robert the Bruce's skull. Not sure of the provenance. 

It says Robertus Scotorum, which I initially read as Robertus Scrotum... And now I can't unsee it. 

Apologies to a national hero and historians, but a big part of being Scottish is having a cheeky sense of humour.
