In 1558 Albrecht V, Duke of Bavaria acquired the library of the humanist, orientalist, philologist, and theologian, Johann Albrecht Widmannstetter. This was the origin of the Bayerische Staatsbibliothek, München.
"Albert was a patron of the arts and a collector whose personal accumulations are the basis of the Wittelsbach antique collection of Greek and Roman antiquities, the coin collection and the Wittelsbach treasury in the Munich Residenz; some of his Egyptian antiquities remain in the collection of Egyptian art. His personal library has come to the Bavarian State Library in Munich, inheritor of the Wittelsbach court library.
"Like an American millionaire of the Gilded Age, he bought whole collections in Rome and Venice; in Venice, after tiresome drawn-out negotiations with the aged Andrea Loredan, he purchased the Loredan collection virtually in its entirety: 120 bronzes, 2480 medals and coins, 91 marble heads, 43 marble statues, 33 reliefs and 14 various curiosities, for the sum of 7000 ducats; 'they were all exported from Venice secretly at night in large chests'. At the same time, squabbles among the heirs of Gabriele Vendramin thwarted him in his attempt to purchase the single most important collection in Venice and paintings and antiquities, drawings by the masters and ancient coins. To house his antiquities he commissioned the Antiquarium in the Munich Residenz, the largest Renaissance hall north of the Alps.
"He appointed Orlando di Lasso to a court post and patronized many other artists; this led to a huge burden of debts (½ Mio. Fl.)" (Wikipedia article on Albert V, Duke of Bavaria, accessed 01-03-2010).
