Art lovers are being warned of upsetting content before they enter the new William Blake exhibition at the Tate Britain. William Blake at the Tate Britain features 300 of his original prints and paintings in the largest collection of his work for nearly 20 years. But visitors are being told his artwork contains 'strong and sometimes challenging imagery' and 'depictions of violence and suffering' as they make their way towards the entrance. Blake was known for his radical and rebellious attitude, exploring struggles in his personal life as well as the political turmoil of eighteenth century Britain.
