A comment on history as told and history as written: in the beginning, as you all know perfectly well, but not all will have stopped to consider it, ALL history was word of mouth. Do you remember the whisper around the table game we played as children at birthday parties? The last in the circle would speak out loud what they had just had whispered in their ear, and it would be NOTHING like what was started around the circle!
So gossip built upon gossip built upon gossip. And politics and tribal hatred came into it big time. You hear the lies being told flat out and blatantly in public today? Much worse then, because no one could trace anything back to the source. Remember: everyone illiterate, no radio, no tv, no newspapers, no printing, no telephone, and so on and on.
Now serious historians can go to the Vatican and other sources of what was written down (wealthy homes, museums, private collections, city and state archives, and so forth) and can actually travel world over to find authentic items and can come up with something closer to reality. I do not believe in Lucrezia's case it is a matter of white-washing at all. I think she was a scape goat.
