Leonardo da Vinci could have experienced nerve damage in a fall, impeding his ability to paint in later life, Italian doctors suggest.
Leonardo da Vinci, who lived from 1452-1519, was an artist and inventor whose talents included architecture, anatomy, engineering and sculpture, as well as painting but his painting skills wore away towards the end of his life
A portrait of the Italian Renaissance artist shows his right hand, wrapped in clothing like a bandage and suspended in a stiff, contracted position. It had been suggested that his hand impairment was caused by a stroke.
But in the Journal of the Royal Society of Medicine, the doctors suggest it was nerve damage that meant he could no longer hold a palette and brush. Experts believe the injury may have forced him to leave many works incomplete.
