One legend contends that Valentine was a priest who served during the third century in Rome. When Emperor Claudius II decided that single men made better soldiers than those with wives and families, he outlawed marriage for young men -- his crop of potential soldiers. Valentine, realizing the injustice of the decree, defied Claudius and continued to perform marriages for young lovers in secret. When Valentine's actions were discovered, Claudius ordered that he be put to death.
During the days that Valentine was imprisoned,
he fell in love with the blind daughter of his jailer. His love for her, and his great faith, managed to miraculously heal her from her blindness before his death. Before he was taken to his death, he signed a farewell message to her, "From your Valentine." The phrase has been used on his day ever since.
