Dr. Roberto Guatelli was a renowned world expert of Leonardo da
Vinci and specialized in building working replicas of da Vinci.
He had built countless such replicas with four assistants.
On February 13th 1967 an amazing discovery was made by American
researchers working in the National library of Spain, Madrid. They
had stumbled upon 2 unknown works of Leonardo da Vinci know as the
"Codex Madrid". There was much excitement regarding this
discovery and the public officials stated that the manuscripts "weren't
lost, but just misplaced".
In 1967, shortly after the discovery of the "Codex Madrid", Dr. Guatelli flew to the Massachusetts university to examine its copy.When seeing the page with the calculator he remembered seeing a similar drawing in the "Codex Atlanticus". Putting the two drawings together Dr. Guatelli built the replica later in 1968.
It was displayed in the IBM exhibition.
After some years controversy about the correctness on the replica arised and IBM removed the replica from its exhibitions
The text beside the replica said:
The whereabouts of the replica today is unknown. Possibly it is somewhere
in one of IBM's storages.
