The painting 'The martyrdom of St. Sebastian' hangs in the National art gallery, London.

The painting was created by one of the most famous workshops of the time - that owned by the exceptionally talented Pollaiuolo brothers in Florence. This booklet is a detailed examination of that painting that tries to answer the question posed by the author "Was this painting innovative?" Read the evidence and decide for yourself, do you agree with the author?
