Everyone in the past was as perverse as you, Rosenfeld? This is pure supposition and publicity-pandering to belittle and defame the memory of a remarkable artist and intellect. There is no way to ever prove or disprove this, so the purpose of bringing it up can only be self-promotion on the part of Rosenfeld, some kind of third-rate art historian. I think this says much more about what Rosenfeld does in his spare time than what Leonardo da Vinci did in his, and then these two dim-bulb reporters fall right into it.
Ping!
