April 23rd is Sant Jordi in Barcelona, a celebration where the main event is the exchange of roses and books between couples. It’s the Catalan equivalent to St. Valentine day.
The tradition of giving a book on April 23rd comes from the universal expo on 1929 in Barcelona, when booksellers went out on the streets to sell books. It was so good for business that they decided to do it every year, on April 23rd, World Book Day.
The rose tradition comes from the legend of Sant Jordi, the story about how good wins against evil, the knight in shiny armour kills the dragon that kidnapped the princess. The knight defeating the evil dragon repeats itself all over Europe since the medieval age.
Legend says that in the village of Montblanc long time ago there was a dragon that scared the villagers and poisoned the water and the animals, but the dragon wasn’t satisfied with that and the villagers decided to sacrifice a person by lot, and the princess was elected to be sacrified.
The dragon took the princess and went to its cave. Then Jordi, a knight in shiny armour appeared in the village, went to save the princess and killed the dragon. The battle took place in front of the king and the villagers of Montblanc, the knight killed the dragon by a spear attack, and from the blood of the dragon on the ground grew red roses. The knight took the most beautiful rose and gave it to the princess.
They headed back to the village were a huge banquet took place celebrating the victory of the knight Jordi.
