The floor of the Chigi Chapel, in the church of Santa Maria del Popolo, sports a striking image of a winged skeleton holding aloft the coat of arms of the Chigi family. The four enlarged letters of the inscription 'MORS ADCAELOS' ('Through Death to Heaven') form the date MDCL (1650), the year the chapel was finally completed.
Skeleton Holding the Coat of Arms of the Chigi family
In 1507 the chapel was granted by Pope Julius II (r. 1503-13) to the Sienese banker Agostino Chigi (1465-1520), one of the richest men of his day. Chigi engaged Raphael (1483-1520), who had worked for him at the Villa Farnesina, to decorate the chapel. Only Raphael's designs for the mosaics in the dome and for the statues of Jonah and Elijah were used. The mosaics were executed by Luigi da Pace, a Venetian artist. In the central roundel is God the Father, while the eight panels depict the Sun, Moon, and the six known planets, each accompanied by an angel with colourful wings.
The statue of Jonah was carved by Lorenzetto, who also started work on Elijah, which was completed by Rafaello da Montelupo.
Vault
In the 1550s, Francesco Salviati frescoed the lunettes and the drum of the dome. He also completed the altarpiece of the Nativity of the Virgin, which had been left unfinished by Sebastiano del Piombo in 1534.
Daniel by Bernini
In the middle of the 17th century, Pope Alexander VII, the great-grandson of Agostino Chigi, commissioned Gian Lorenzo Bernini to complete the family chapel.
Habbakuk and the Angel by Bernini
Bernini carved the statues of Habakkuk and the Angel and Daniel and the Lion and completed the pyramidal tombs of Agostino Chigi and his brother Sigismondo, which had been started by Lorenzetto and Rafaello da Montelupo, probably to a design by Raphael.
Detail of Frieze
The 'dropped' friezes between the capitals are embellished with festoons of fruit, above which there are a variety of curious images, such as a bearded male head wearing a hat that takes the form of the heraldic arms of the Chigi family, namely a star and six montini.
