Sorry Joar, for this duble post, but I found a good Saint Ambrose! If the Saint doesn't interest you, please tell me, I'll stop my search, no problem! 
Saint Ambrogio was born in Trier or Augusta Treverorum, in 339 or 340 AD and died in Milan in 397. I'll not add more informations about his life, because probably they are not needed, I'll say only that the Saint who was also Bishop of Milan, was one of the most important figures of the church in IV century, famous is the so called 'Humiliation' of Theodosius the Great by the Saint.
In the years 379 - 386 AD was built for his inspiration, the great Basilica of Saint Ambrose in Milan, which is today the most famous church of Milan. The Basilica of Saint Ambrose preserves the remains of the Saint in the Sacello of Saint Vittore in Ciel d'Oro. Here there is this very interesting Late Antique Mosaic which is considered a real protrait of the saint still alive, in fact the Sacello was built when Ambrose was still alive.
Here the Basilica of Sant'Ambrogio today in Milan (I'm not going to talk about the church, because it wouldd be off-topic and because I well know that sadly one of the most boring experience in the life of an human being is listening an architect speaking about architecture!!

....but the history of this ancient church is very, very, very interesting!!!
