Roman fortifications, York, © Kaly99, <a href='http://commons.wikimedia.org/wiki/File:Roman_Fortifications_in_Museum_Gardens_York.jpg'target=_new'>Wikimedia Commons</a>
His remains were found in York. Analysing the isotopes in his tooth enamel shows that in his early years Piscarius ate food that was not commonly eaten in Britain. At first, it was thought that he had eaten a lot of fish. Now scientists think it might be millet.
