A collection of documents written by Leonardo da Vinci give an insight into an extraordinary mind.

The Chester Beatty Library in Dublin is to display documents written by Leonardo da Vinci.

Handwritten in Italian in his characteristic mirror writing, this manuscript is one of a number of journals written by Leonardo da Vinci during his prolific career as a scientist, artist, astronomer, and inventor.

The 72 page document known as The Codex Leicester dates from the early 1500s and contains theories on the movement of water, the reflection of light from water and the perception of colours.

The Renaissance manuscript was bought at auction in 1994 by billionaire and philanthropist Bill Gates for over $30 million. Each year, the Gates family allow The Codex Leicester to go on display in a different city.

This summer, Leonardo's writings have come to Dublin.

Dr Michael Ryan, Director of the Chester Beatty Library, describes Leonardo da Vinci as "a restless genius". The document provides an interesting insight into the marvellous mind of a many talented man..

The paper of the codex is almost five hundred years old and very fragile. The Chester Beatty Library has developed a unique lighting system to make sure that the manuscript is both viewed and protected at the same time.

The Codex Leicester will be on display at the Chester Beatty Library until the 12 August. While admission is free, booking is strongly advised as demand for tickets is high.
