According to tradition, the names of the Magi in Greek were Melchior, Gaspar and Balthasar. Matthew, in his Gospel, tells of the question which burned in the hearts of the Magi: “Where is the infant king of the Jews?” (Mt 2: 2). It was in order to search for him that they set out on the long journey to Jerusalem. This was why they withstood hardships and sacrifices, and never yielded to discouragement or the temptation to give up and go home. Now that they were close to their goal, they had no other question than this.
You should know that in 1164 the relics of the Magi were escorted by the Archbishop of Cologne, Reinald von Dassel, from Milan, across the Alps, all the way to Cologne, where they were received with great jubilation. On their pilgrimage across Europe these relics left visible traces behind them which still live on today, both in place names and in popular devotions … here in Cologne one of the Magi has been identified as a Moorish King of Africa, so that a representative of the African Continent has been seen as one of Jesus Christ’s first witnesses.
In honor of the Magi the inhabitants of Cologne produced the most exquisite reliquary of the whole Christian world and raised above it an even greater reliquary: Cologne Cathedral. Along with Jerusalem the “Holy City”, Rome the “Eternal City” and Santiago de Compostela in Spain, Cologne, thanks to the Magi, has become down the centuries one of the most important places of pilgrimage in the Christian West.
