500th death anniversary of Leonardo da Vinci
This portrait, newly identified as Leonardo da Vinci, is going on display in London as the world marks the 500th anniversary of the death of the artist and inventor.
Until 6 May, 144 of Leonardo's drawings are on display in 12 simultaneous exhibitions across the UK in venues including Belfast, Cardiff and Glasgow.
The original mural, seen above, is one of only around 20 paintings Leonardo completed and was commissioned for the refectory of the Convent of Santa Maria delle Grazie in Milan.
The Louvre in Paris expects huge demand for its forthcoming Leonardo da Vinci exhibition this October, urging visitors to book a time slot ahead of their visit.

Entitled Landscape 8P, it was sketched when the artist was 21. The museum describes the image as "a kind of palimpsest for all of Leonardo's future output".
