The presbytery pavement is raised, housing the
crypt underneath, while the nave and the aisles, separated by columns, have vaults and wooden truss covers respectively. The right aisle was once occupied by the Chapel of St. James (
San Jacopo), built by bishop Atto in the mid-12th century to house the relics of
Saint James brought from
Santiago de Compostela. The silver altar of the saint can be seen today in the Crucifix Chapel.
Chapel of the Blessed Sacrament The Chapel of the
Blessed Sacrament (
Capello del Santissimo Sacramento), which houses the
tabernacle, is also known as the Chapel of San Donato from a painting portraying the
Madonna Enthroned between St. John the Baptist and St. Donatus (c. 1475–1486), on the right hand wall. The painting had been commissioned from
Andrea del Verrocchio by the heirs of
Donato de' Medici and was started by Andrea but, left unfinished, was completed by
Lorenzo di Credi. The bishop next to the Madonna has been identified as Saint Zeno. In the middle is the
Assumption of the Virgin by
Giovanni Battista Paggi (1590–1600). Next to the chapel's entrance is the tomb of Donato de' Medici (1475), Bishop of Pistoia, attributed to
Antonio Rossellino.
Crucifix Chapel This chapel contains the altar of Saint James, in
embossed silver sheet, which was moved here in 1953. It was begun in 1287, when Andrea di Jacopo d'Ognabene was commissioned to make representations of the
Madonna and Child for the rear of the altar, and, for the front section, of
Stories of the New Testament,
Christ in Majesty between Mary and St. James and
Three Stories of St. James, which he finished in 1316. In addition,
Pace di Valentino, a Sienese goldsmith, created some of the figures surrounding St. James. Giglio Pisano executed the large silver statue depicting
St. James Enthroned (1349-1353), commissioned as thanksgiving after the end of the
Black Death in 1348. The two side
antependia were executed by Leonardo di Ser Giovanni and Francesco Niccolai, with
Stories of the Old Testament and
Stories of St. James, between 1361 and 1371. Other works include the
Apostles, St. Eulalia, Bishop Atto, St. John the Baptist and Salome by Piero d'Arrigo Tedesco (1380–1390), another
Christ in Majesty with St. Anthony Abbot, St. Stephen and the
cusp by Nofri di Buto and Atto di Piero Braccini (1394–1398).
Filippo Brunelleschi decorated the front part with two busts of prophets (1401). The other sides were decorated by Piero d'Antonio da Pisa and Domenico da Imola.
Aisles Works in the south aisle include: • Triptych of
Crucifixion between the Madonna, Sts. John, Jerome and James' (1424), by an unknown artist. • A copy of the
Annunciation by
Domenico Cresti • The precious
Crucifixion (1274) by
Coppo di Marcovaldo and his son Salerno. It includes six panels with the
Capture of Jesus,

Deposition of Jesus in the Sepulchre,
The Three Marys at the Sepulchre • Tomb of
Cino Sinibuldi da Pistoia (1337), attributed to
Agostino di Giovanni Works in the north aisle include: •
Monument of Cardinal Forteguerri, commissioned from
Andrea del Verrocchio by the
Consiglio Generale of Pistoia in 1473. After the death of Verrocchio (1488),
Lorenzo Lotti, known as il Lorenzetto, finished the work by sculpting the statue of Charity. The current surround and other details were executed in 1753. •
Madonna delle Porrine, 14th-century fresco by an unknown artist. • Statue of
Pope Leo XI, bishop of Pistoia in 1573 (1618), also from an unknown artist. • Tomb of bishop Federico Alamanni (1776), by an unknown artist. •

Presbytery The vault of the presbytery is decorated by frescoes by Domencio Cresti, depicting the
Father in Glory,
Fall of the Rebel Angels,
Fall of Adam and the
Annunciation (1602). The organ is from 1793. In the apse is a painting by
Cristofano Allori portraying the
Resurrection (1606–1610), beside which are two clay statues of Saint Zeno and Saint James (1609), attributed to the school of
Giambologna. To the right of the high altar is a
Pentecost by
Gregorio Pagani (1602), while on the left is an
Ascension by
Benedetto Veli (1606). Salerno di Coppo executed the fresco of the Madonna and Child on the pilaster in the nave (1475). On the right is a bronze candelabrum by
Maso di Bartolomeo (1442), while in the left aisle is the cenotaph of bishop
Gherardo Gherardi (1703) and, in the right one, the tomb of bishop Alessandro Del Caccia (1650), and the funerary monument of bishop Leone Strozzi (1695), both by unknown sculptors. The pulpit was designed by
Giorgio Vasari (1560). Next to the right entrance is a sculpted
stoup attributed to
Nicola Pisano's workshop.
Others The Chapel of the Last Judgement houses fragments of a fresco by Giovanni da Ponte, dating to 1420–1425. The lateral wall fragments have recently been identified as a depiction of
Dante's Inferno. The
crypt is that of the Romanesque building, and was originally divided into a central and side spaces by columns, and had three apses. After the construction of the Baroque tribune, the central room was destroyed and the side ones buried. After the 1960s restoration, here were found two capitals, fragments of columns, fragments of 12th-century frescoes, and two marble slabs from the late 12th century. The counter-façade houses the Arch of St. Atto, with three marble bas-reliefs from 1337. The baptismal font, to a design by
Benedetto da Maiano (1497), can be seen on the left of the main entrance. In the tympanum over the latter is also a 13th-century fresco by an unknown 13th-century master, while next to the right entrance are frescoes of the
Virtues by Bonaccorso di Cino (1347) and, near the left entrance, the tomb of Bishop Baronto Ricciardi (14th century). == Footnotes ==
