Baltasar = African
Gaspar = Asian
Melchor = European
These men were "hierophants" who brought gifts of myrrh, incense and gold to the Infant of Nazarath and his parents on January 6th, the Epiphany.
In Spain, in 1866, this day had beome the official day to celebrate with the "Calbagata de Los Reyes" ( national Parade) and an official national holiday .. The most important holiday in Spain .. Papa Noel or Santa Klaus is called Noche Buena and this is a reunión of dear ones and family - who have a large fish dinner called La Vigilia ..
It is celebrated in a similar way to Christmas, however, gifts are given on this day verses the 25th of December and a large lunch is served with a cake called El Roscon de Los Reyes ( a large ring prepared with bread flour, unbleached flour, and filled with whipped cream and topped with glazed fruits and confectioner´s sugar ) .. The translation is " the ring of the 3 Kings " ..
In France ( tart with a Crown ) and Italy ( Befana the good witch ) the festivities are similar however, with nuances ..
