Who was Pope Saint Clement I?

Pope Clement I served as pope for just over a decade before being martyred around the year 101AD by the Roman emperor Trajan. He was tied to an anchor and thrown into the sea off the Crimea - modern-day Ukraine. As a result he is the patron saint of mariners. Archbishop George Stack, Chair of the Bishops' Conference Patrimony Committee, tells us about St Clement having received a relic - a bone fragment - of the saint from James Rubin, owner of Enviro Waste - the company that discovered it in some rubbish collected in central London.
