For over 400 years, rumours have surrounded the death of Danish astronomer Tycho Brahe, including one which suggested that Brahe was murdered using mercury by his assistant Johannes Kepler. Now, after two years, evidence from the scientist's exhumed body disproves the theory.
'To definitively prove or disprove these much debated theories, we took samples from Tycho Brahe's beard, bones and teeth when we exhumed his remains in 2010. While our analyses of his teeth are not yet complete, the scientific analyses of Tycho Brahe's bones and beard are,' explains Dr Jens Vellev, an archaeologist at Aarhus University in Denmark. The result: Normal concentrations of mercury.
