The Mona Lisa and the Vitruvian man are among Leonardo da Vinci's most famous works – skilfully depicting the human form in perfect proportions.
He honed his talents in this area, through a detailed study of human anatomy, producing hundreds of drawings between 1480 and 1513.
Leonardo da Vinci: Anatomist is the largest-ever exhibition of this work, containing 87 examples drawn in chalk, pen and ink, or with a metal stylus.
These were selected from piles of notes and drawings that were left, unsorted by Leonardo when he died, and obtained by Charles II in the seventeenth century for the Royal Collection.
Some of the pages contain notes in "mirror writing" – which is normally written with the left hand. Da Vinci was known to paint with his left hand, although some records suggest he may have been ambidextrous, meaning he was able to use either hand.
The drawings are on display in the Queen's Gallery, Buckingham Gate, Buckingham Palace road, London SW1 from now until 7 October.
