In the recently restored Piccolomini Library Pinturicchio's fresco cycle is a rare example of a unified decoration of the early sixteenth century. Well-suited to Pinturicchio's skills and to a somewhat provincial Siena, his lyric style fits comfortably into the medieval setting of the Cathedral. The subject matter concerns incidents in the life of Pius II, the Sienese pope and humanist, an unusually complete program for someone neither a saint nor a ruler.

The donor of the library and its furnishings was Francesco Todeschini (1439-1503) who wished to create a monument to his family and a memorial to his mother's brother Enea Silvio Piccolomini who had served as Pope Pius II from 1458 to 1464. In 1460 Pius II elevated Todeschini to the rank of cardinal and permitted him to assume the Piccolomini name and the family's coat of arms. In 1503 Francesco succeeded Pope Alexander VI as Pius III but his reign was brief, he died twenty-six days later.

The contract for the decoration of the library was signed in the presence of Francesco Todeschini-Piccolomini on June 19, 1502 and the painting was finished in April 1508.

The source for the ten episodes from the life of Pius II was Pius II's autobiography, the famous Commentarii, written between 1462 and 1464. In addition to being the official life story of a pope, it is a fascinating political and historical chronicle. The narratives are illustrated with descriptive clarity, the figures precisely drawn, the unatmospheric landscape bright and sharply defined.
