A place where the sacred and the profane come together. The floor of the cathedral is covered in esoteric symbols
and religious stories
, such as the Sibyls from Ancient Greek tradition, the Massacre of Innocents, the life of Moses and much more. The Piccolomini Library
is found in the right-side nave, which – despite its name – has never held the books of Pope Pius II. Michelangelo
did, however, work within the Piccolomini Chapel for three years at the beginning of the 1500s, creating 4 statues, which are kept in the lower recesses.
