Friday marks the Christian celebration of the revelation of God the Son in Jesus Christ, also celebrated as the day the Three Kings brought gifts to the baby Jesus.

The word "epiphany" comes from the Ancient Greek "theophany", meaning "vision of God." January 6 is commemorated throughout the world with festivals, feasts, parades, and a whole host of quirky and odd traditions.

In Bulgaria, hundreds of young men have also plunged into rivers and lakes across Bulgaria to retrieve crucifixes cast by priests. It is believed that the person who retrieves the cross will be freed from evil spirits that might have troubled him.

Celebrations in Italy centre around the figure of "La Befana", a witch-like persona from Italian folklore who brings sweets and gifts to children on the night before Epiphany. If the child has been bad, she brings lumps of black coal instead.

In Mexico City, it is traditional to bake a giant cake, known as "Roscon de Reyes" on the day of Epiphany. This year's cake was reportedly made using 38,000 eggs, 1,000kg of fruit, over 2,600kg of sugar and 600kg of marmalade. More than 2,000 bakers took part in making the treat, which stretches 740m and weighs about nine tonnes.
