Highlights of the Piccolomini Library

The Three Graces
In the center of the library, you will find the magnificent sculpture of the Three Graces. The Three Graces is a sculpture of three nude women, representing the daughters of Zeus, and is a 2nd-century copy of the original. The sculpture was discovered in the middle of the fifteenth century and was purchased by Francesco Todeschini Piccolomini from Cardinal Prospero Colonna in Rome. It is said that many non-secular, including a pope, were offended by the nudity of the statue. However, being a lover of art, the wishes of the Pope were respected, and the statue's place in the Piccolomini Library was justified as it was meant to be a secular room.

The Life of Aeneas Silvius Piccolomini
There are ten wall paintings around the Piccolomini Library that depict the life and career of Enea Silvio Bartolomeo Piccolomini, to whom the library is dedicated to. The cycles of frescoes are done in the Renaissance style and are very elaborate in the use of characters and its landscape. Some of the paintings depict Piccolomini as a youth leaving for the Council of Basil. In another, he is named as the imperial poet by HRE Frederick III and Piccolomini as a cardinal. One fresco depicts his ascension to being Pope Pius and another shows him announcing the launch of a crusade. It took Pinturicchio seven years to complete the cycle of frescoes. It is said that Raphael, who was an apprentice of Pinturicchio, was often used as a model for various characters in the frescoes.

Illuminated Codices
The books of the Piccolomini were never transferred to the library from Rome. What was brought over was a group of 15th-century codices and illuminated manuscripts that included choir books and liturgical books. They are masterfully illustrated by Italian illustrators like Girolamo da Cremona and Liberale da Verona from the north of Italy and other Sienese artists.
