ANSA is reporting:
"The hidden drawings which lie underneath one of Leonardo Da Vinci's most famous works were shown to the public for the first time in Florence this week .A bloody battle scene, a clutch of figures rebuilding a ruin and even an elephant were all sketched by Leonardo in detail in the preparatory 'underdrawing' for his 'Adoration of the Magi' .
Yet in the version of the painting known to the world, in which much of the drawing is reproduced, none of these particular elements is visible.
I wish I would have heard about this before it happened, I am not sure exactly what "public" actually got to see it.
