The legacy of a Liverpool man who changed the way we look at the night sky was almost lost to history.
Jeremiah Horrocks died when he was just 22, but his discoveries paved the way for Isaac Newton and "changed the way we see the universe", according to the producers of Horrox, a new play about the forgotten hero.
He was born in Toxteth Park, a former royal deer park near Liverpool, in 1618. The Ancient Chapel of Toxteth he attended is still there, surrounded by houses and a derelict cinema where trees once stood. A plaque inside is one of few memorials to him in the city.
