Legacy is about the rivalry between Leonardo and Michelangelo – in particular their differing attitudes to their legacy.

It also draws on other rivalries such as architects Richard Rogers and Norman Foster – both supremely talented but one more interested in new ideas and the other striving to prove (with some justification) to be the best in the world EVER. Some rivalries fizzle out over time, others last a lifetime. Some are purely business, others incredibly personal. Most of them encourage great works – but occasionally heartbreaking disappointments.
