One day a Roman jailer come to Valentine with his blind daughter.  Though her condition looked grim, Valentine agreed to see the young girl regularly and to pray for her.  Several weeks later, Valentine was arrested by Roman soldiers.  All his medicines and medical equipment were destroyed.  The jailer wanted to help Valentine, but could do nothing for  him.  Valentine knew he would be executed.  He asked the jailer for pen and paper and wrote a farewell note to his blind daughter.  Later that day, on February 14, 270, Valentine was executed.

When the jailer went home, he gave his daughter the note from Valentine.  When the girl opened the note, a yellow crocus spilled out.  The note simply said, "From your valentine."  As the crocus fell onto her hand, her eyesight was miraculously restored.

St. Valentine was venerated by Pope Gelasius I in 496.  February 14, the day of his death, is his feast day.  In 1969 he was dropped for the official liturgical calendar by the Roman Catholic Church.
