The Biblioteca Ambrosiana is a historic library in Milan, also housing the Pinacoteca Ambrosiana, the Ambrosian art gallery. Named after Ambrose, the patron saint of Milan, it was founded in 1609 by Cardinal Federico Borromeo, whose agents scoured Western Europe and even Greece and Syria for books and manuscripts. Some major acquisitions of complete libraries were the manuscripts of the Benedictine monastery of Bobbio (1606) and the library of the Paduan Vincenzo Pinelli, whose more than 800 manuscripts filled 70 cases when they were sent to Milan and included the famous Iliad, the Ilia Picta.
Among the 30,000 manuscripts, which range from Greek and Latin to Hebrew, Syriac, Arabic, Ethiopian, Turkish and Persian, is the Muratorian fragment, of ca 170 A.D., the earliest example of a Biblical canon and an original copy of De divina proportione by Luca Pacioli. Among Christian and Islamic Arabic manuscripts are treatises on medicine, a unique 11th-century diwan of poets, and the oldest copy of the Kitab Sibawahaihi.
Artwork at the Pinacoteca Ambrosiana includes da Vinci's Portrait of a Musician, Caravaggio's Basket of Fruit, and Raphael's cartoon of The School of Athens.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
