According to the Legenda 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 have performed a miracle by healing the blind daughter of his jailer.
Since Legenda Aurea still provided no connections whatsoever with sentimental love, appropriate lore has been embroidered in modern times to portray Valentine as a priest.
Still in order not to break with tradition, I would like to Wish a happy Valentine's day to all those people with partners and Happy Valentine's day to all those still looking for love in their life. Me, I am happy with my choices, at this point in time lol xx
