The Catholic Encyclopedia also speaks of a third saint named Valentine who was mentioned in early martyrologies under date of February 14. He was martyred in Africa with a number of companions, but nothing more is known about him. Some sources say the Valentine linked to romance is Valentine of Rome, others say Valentine of Terni. No romantic elements are present in the original early medieval biographies of either of these martyrs.

Legend Aurea: St Valentine was persecuted as a Christian and interrogated by Roman Emperor Claudius II in person. Claudius was impressed by Valentine and had a discussion with him, attempting to get him to convert to Roman paganism in order to save his life. Valentine refused and tried to convert Claudius to Christianity instead. Because of this, he was executed. Before his execution, he is reported to haveperformed a miracle by healing the blind daughter of his jailer. Saint Valentine was killed (beheaded) because he continued to marry young couples even though Claudius forbade it. Apparently Claudius thought that married soldiers weren't as good as single soldiers.

In Great Britain, Valentine's Day began to be popularly celebrated around the seventeenth century. By the middle of the eighteenth century, it was common for friends and lovers in all social classes to exchange small tokens of affection or handwritten notes. By the end of the century, printed cards began to replace written letters due to improvements in printing technology. Ready-made cards were an easy way for people to express their emotions. Americans probably began exchanging hand-made valentines in the early 1700s. In the 1840s, Esther A. Howland began to sell the first mass-produced valentines in America.

In Wales wooden love spoons were carved and given as gifts on February 14th. Hearts, keys and keyholes were favourite decorations on the spoons. The decoration meant, "You unlock my heart!"

In some countries, a young woman may receive a gift of clothing from a young man. If she keeps the gift, it means she will marry him.

If she saw a goldfinch, she would marry a millionaire.
