A popularly ascribed hagiographical identity appears in the Nuremberg Chronicle (1493). Alongside a woodcut portrait of Valentine, the text states that he was a Roman priest martyred during the reign of Claudius Gothicus. He was arrested and imprisoned upon being caught marrying Christian couples and otherwise aiding Christians who were at the time being persecuted by Claudius in Rome. Helping Christians at this time was considered a crime. Claudius took a liking to this prisoner. However, when Valentinus tried to convert the Emperor, he was condemned to death. He was beaten with clubs and stones; when that failed to kill him, he was beheaded outside the Flaminian Gate. Various dates are given for the martyrdom or martyrdoms: 269, 270, or 273.
