lived by the grace of God in the desert, was created by Lorenzetto but it was finished by Raffaello da Montelupo around 1523/24. In two other niches are sculptures by Bernini: Habakkuk and the Angel (1656–61) that took him by the hair and transported him to Babylon to succour Daniel and the Lion, who is represented in the corresponding niche on the opposite wall, sculpted by Bernini in 1655-56. With these two statues Bernini created a spatial relationship that enlivened the entire chapel, turning its classical form to a new religious use. Pyramids On the side walls are the matching pyramidal wall tombs of Agostino Chigi (died 1520) and his brother Sigismondo (died 1526), each represented in a medallion, looking towards the altar. The monuments were probably designed by Raphael but their execution was left to Lorenzetto who nearly finished one tomb in 1522. As for the other pyramid, the evidences are inconclusive. The pentimenti at the marble cornices suggest that originally only one pyramid for the eastern side was envisaged. The first time when "sepulchres" are mentioned in plural form is in a contract between the Chigi family and Bernardino da Viterbo on 8 April 1522 when the sculptor was commissioned to add the final touches to Lorenzetto's work. Nonetheless the other pyramid was still recorded as mostly unbuilt in 1552 when the Chigis paid their long-standing debt towards Lorenzetto's family. (In the proceedings the base of the second pyramid and the slabs for the marble covering were also duly recorded.) Most probably the second monument was only erected by Fabio Chigi for his great-grandfather, Sigismondo. In 1996 Antonio Pinelli discovered the original 1552 contract in the Getty Research Institute which had only been known through an inaccurate 19th-century transcription. He interpreted the text as a proof that the pyramid of Agostino was originally planned for his wife, Francesca Ordeasca together with the bronze relief of Christ and the Samaritan woman. This theory remains disputed but the corrected text indeed speaks about a female tondo which had not been executed by Lorenzetto - a hint that the second pyramid was prepared for a woman, most probably Ordeasca. Pyramidal tombs were a new invention at the time but pyramids were the traditional symbols of eternity and immortality. The Chigi tombs were inspired by antique sources because they recalled the tombs of the pharaohs and two famous Roman funeral monuments, the
