Most people have heard of Leonardo da Vinci. Most will think of the Mona Lisa. But for me, its his drawings that capture the imagination. His sketches and technical drawings have a character and delicacy that just fascinates me. Da Vinci was one of the first artists whose work captured me, and it still does. Nottingham Castle is one of four venues across the UK and Ireland that is playing host to a touring exhibition of ten drawings from the Royal Collection. The drawings show the variety of da Vinci’s interests and curious nature, spanning anatomy, map making and engineering to botanicals.
