The three wise men were visitors who visited Jesus when he was born. They wanted to pay homage and gave him three very symbolically wealth presents: Gold, Incense and myrrh.
Melchor (Magalath) is a White haired and long white beard old man. He gave myrrh to Jesus. A very appreciate material in the antiquity. Myrrh is the symbol of MEN. Gaspar (Galgalath) is the youngest of the three and he comes from Asia. He gave the incense to the new born. This is the symbol of GOD. Baltasar (Serakin), originating from Africa, gave the most appreciated noble metal to Jesus: Gold. This is the symbol of the KING.
Every Christmas, children write a letter to their majesties. In the message, they write to the kings if they have been good and they have had good grades. Then they ask for the presents they would like to receive.
If they are lucky and they have been really good during all the year (the three kings know it because the can see everything), the three wise men bring them what they wish. Otherwise, if they have been bad, their majesties bring them coal.
The magic of the three wise men from Orient starts the night of the 5th of January, the cavalcade night. All the cities of Spain are on party to welcome Melchor, Gaspar and Baltasar. All the royal pages have travelled with them. They are who, during the night, will help them to share out all the presents. They have a lot of homes to visit and one night it is not a lot of time. In some homes, children receive the presents the same night after the cavalcade. Others have to wait until next morning.
