http://www.bbc.co.uk/news/uk-england-humber-20571213 Not sure why a BBC report from someone in Rome is showing up with a humber url, but there you go.
Some of da Vinci's work is actually on show at the moment at the Ferens along with some Andy Warhol's, if you like his stuff. The da Vinci stuff is interesting in the fact that in trying to see what language the writing was in, he lived in France for quite a while although born in Italy, one of the guys working in the gallery, curators? said that he actually wrote left handed and so back to front but he didn't know what language.
That sounds bollocks. Why would he need to write back to front just because he was left handed? I'm left handed and I'm perfectly capable of writing with fountain (ie wet ink) pens. It just means writing with your hand below the writing rather than around it so that your hand doesn't run over the ink before it dries.
