was the "Mona Lisa" really DaVinci's Self-Portrait?

First of all, I think that remark was uncalled for.

It wasn’t in reference to you - it was about the nitpickers, jumping in. Sorry.

Second, I have yet to find a single biographer or art historian who says that “Da Vinci” is a valid surname for the great master, Leonardo.

“So what?” someone might say. Well, it seems to me that on a forum that’s dedicated to fighting ignorance, such attention to detail is warranted. The experts certainly don’t seem to think that its an invalid distinction.

OK, what is the distinction, exactly?
