The legend was retold in later texts, and in the "Nuremberg Chronicle" of 1493 AD, involved the Roman priest being martyred during a general persecution of Christians. The text states that St. Valentine was beaten with clubs and finally beheaded for giving aid to Christians in Rome. The "Golden Legend" of 1260 AD recounts how St. Valentine refused to deny Christ before the "Emperor Claudius" in 270 AD and as a result was beheaded. Since then, February 14 marks Valentine's Day, a day set aside by the Christian church in memory of the Roman priest and physician.
