The Three Wise Men - In Cologne, Germany

Reliquary Of The Three Wise Men
Cologne Cathedral, Germany
In 1162 (some sources say 1164), the relics of The Three Magi were brought to Cologne, Germany.  They are now kept in a beautiful three-leveled reliquary above and behind the high altar of Cologne Cathedral.

Adoration of the Magi
by Vicente Gil (c. 1465-1536)
The Roman Martyrology lists the Three Wise Men as saints within the July 24 entry ... a day set aside to remember these searchers of truth and recall that their relics were kept safe and delivered to the Cologne Cathedral in 1162/1164.  January 6, the traditional feast of Epiphany is a day which honors the visit these Magi (three is just a traditional guess based on the fact that three gifts were mentioned in the Bible) made to pay homage to the baby Jesus.

A Reasonably Close Translation:
In Cologne in Lotharingia (the region where Germany, France, and Switzerland come together today), the translation/moving/arrival of the relics of The Three Magi, the wise men from the Orient who, bearing gifts, came to Bethlehem to contemplate in the Child the mystery of the Glory of the Only-Begotten Son.
