A campaign has begun for a statue of a bishop credited with coming up with his own "Big Bang" theory, centuries before anyone else.
Robert Grosseteste was an English statesman, scholastic philosopher, scientist, theologian and Bishop of Lincoln from 1235 to 1253.
Born in Suffolk in 1175 - he was ahead of his time according to the theologian leading the campaign.
Dr Jack Cunningham said he deserved recognition for his achievements.
The theology lecturer, from Bishop Grosseteste University in Lincoln, said: "Eight hundred years before they came up with the theory about the Big Bang - he came up with something that is incredibly similar."
"A theory of how the universe was created by light and the expansion of light dragging matter around," he said.
"It is outstanding as he did it without computers or telescopes."
He was also the first scientist to identify light refraction as the cause of rainbows.
Dr Cunningham is now campaigning to get support in "paying tribute to Britain's forgotten scientist philosopher", who apart from having the university and a minor planet named after him, remains largely unknown.
"It is inconceivable that this would happen if Grosseteste had been born in Paris, Madrid or Milan," he said.
"We're calling on the city's authorities to mark the achievements of Robert Grosseteste properly."
The campaign was announced at a university conference in Lincoln, attended by scholars from all over the world.
