Italians try to crack Leonardo da Vinci DNA code with lock of hair

Hair tagged as polymath's in US collection to be tested against remains in French grave

Two Italian experts are set to perform a DNA test on a lock of hair that they say might have belonged to Leonardo da Vinci.

The hair strand was found in a private collection in the US and will go on display for the first time at the Ideale Leonardo da Vinci museum in Vinci (the Tuscan town where the artist was born), from 2 May, the 500th anniversary of the artist's death.
