The inlaid marble
mosaic floor is one of the most ornate of its kind in Italy, covering the whole floor of the cathedral.
Giorgio Vasari, an Italian Renaissance painter and architect, claimed the floor was “
the most beautiful … great and magnificent pavement ever made.” This undertaking went on from the 14th to the 16th centuries, and about forty artists made their contribution, the majority of whom were Sienese. The floor consists of 56 panels in different sizes. Most have a rectangular shape, but the later ones in the transept are
hexagons or
rhombuses. They represent the
sibyls, scenes from the
Old Testament,
allegories,
virtues, and figures from the ancient world. Most are still in their original state. The earliest scenes were made by a
graffito technique: drilling tiny holes and scratching lines in the marble and filling these with
bitumen or mineral
pitch. Giovanni paciarelli, schema del pavimento del duomo di siena, 1884.jpg|A lay-out of the floor of the cathedral Inside of Siena Cathedral (5771999020).jpg|

Nave and aisles Nave The nave contains scenes from
classical antiquity, which is very unusual in a church from this time period. These additions were primarily included due to the influence of two Sienese popes,
Enea Silvio Piccolomini and
Francesco Tedeschini Piccolomini, who believed that classical authors and figures held knowledge that is applicable across faith traditions. At the entrance of the nave is a scene containing
Hermes Trismegistus, a popular figure of the fifteenth century who was seen as "the founder of human wisdom." Designed by
Giovanni di Stefano in 1488, this panel welcomes visitors into the church and introduces the theme of knowledge that develops throughout the nave and side aisles.
The She-Wolf Suckling Romulus and Remus, or
The She-Wolf of Siena was originally created in the 1360s but heavily restored by Leopoldo Maccari in 1865. It portrays a wolf in the center surrounded by eight smaller circles, each depicting the emblem of major Italian cities.
Allegory of the Mount of Wisdom was designed by
Pinturicchio in 1505 and completed in 1506 by Paolo Mannuci. This complicated scene includes a feminine personification of Fortune who is leading a group of wise men up a rocky, dangerous path to great the female
personification of Wisdom. The final panel in the nave is
Wheel of Fortune (completed in 1372 and restored in 1864 by Leopoldo Maccari). The central image is of a wheel, where a king sits at the top and three male figures cling to the wheel. Surrounding the wheel are four figures depicting philosophers from the ancient world.
Side aisles The side aisles along the nave are decorated with ten panels (five in each aisle) of the
Sibyls. Each panel contains a Sibyl that is an allegorical representation of the known world of the time, as identified by an accompanying inscription:
Persian Sibyl,
Hellespontine Sibyl,
Eritrean Sibyl,
Phrygian Sibyl,
Samian Sibyl,
Delphic Sibyl,
Libyan Sibyl,
Cimmerian Sibyl,
Cumaen Sibyl, and
Tiburtine Sibyl. The effect of these allegorical figures represent the universality of the Christian message. Each full-length Sibyl is contrasted against a black and red background, and illustrated in a variety of poses with flowing robes.
Transepts and chancel The scenes in the
transepts and
chancel represent biblical stories and mark the thematic transition from the scenes in the naves and aisles, which depicted figures from
classical antiquity. The biblical scenes all focus on the theme of humanity’s
salvation. In the Siena Cathedral, the chancel encompasses the
crossing, the area below the dome, extending to the altar.
Left transept The left transept contains three large panels:
The Expulsion of Herod,
The Slaughter of the Innocents, and
The Story of Judith.
The Expulsion of Herod by
Benvenuto di Giovanni (1484–1485) in an incredibly intricate scene representing God’s revenge against
Herod, the persecutor of John the Baptist.
The Slaughter of the Innocents by
Matteo di Giovanni is one of the most awe-inspiring panels of the cathedral, and has evoked emotional responses from visitors since its creation in 1481. The panel articulates the desperation of the mothers who are trying to save their babies from the slaughter of malicious guards.
The Story of Judith by
Francesco di Giorgio Martini (1473), located near the pulpit, depicts the Old Testament narrative of
Judith beheading
Holofernes, an enemy general.
Chancel The majority of the panels in the chancel are grouped together in a large hexagonal portion of the pavement and depict
Scenes from the Lives of Elijah and Ahab. Each of these scenes are either designed within a hexagonal panel or smaller rhombus-shaped panel. The upper half of these scenes (four of the seven hexagons and two of the six rhombuses) were completed from 1519–1524 by
Domenico Beccafumi, who was the most renowned Sienese artist of his time. He worked on cartoons for the floor for thirty years (1518–1547) and made vast contributions to the cathedral’s pavement. The lower portion wasn’t completed until 1878 by
Alessandro Franchi. Beccafumi’s eight-meter long frieze
Moses Striking Water from the Rock was completed in 1525. The work marks a technical and stylistic shift from Beccafumi’s earlier work. Here, the artist used different tones within the same piece of marble to create figures heavily contrasted by light and shadow. The subsequent section, also by Beccafumi, portrays
Scenes from the Life of Moses on Mount Sinai. The large panel, completed from 1525–1529, is a continuation of the previous story and employs a similar technical and stylistic method. Rather than isolating each scene within a panel, the entire panel merges the scenes together in one combined section. Next are five panels arranged horizontally:
Joshua Defeats the Five Kings of the Amorites,
David the Psalmist between
David the Slingsman and
Goliath Falling Backwards, and
Samson Chastising the Philistines. The scenes portraying David are credited to Domenico di Niccolò dei Cori (1413–1423), the first known artist to work on the panels. His successor, Paolo di Martino, completed
Joshua Defeats the Five Kings of the Amorites and
Samson Chastising the Philistines between 1424 and 1426 which contain more details than the previous panels. The final panel in the chancel, located directly in front of the altar, is
Abraham’s Sacrifice of Isaac. Completed in 1547 by Beccafumi, the scene contains one large panel with the story, surrounded by smaller rectangular panels of related scenes. Bordering the main altar is a geometric pattern containing five circular panels which depict
Mercy and
The Four Cardinal Virtues (Fortitude, Justice, Prudence, and Good Government)
. The panels date from 1406, as established by a payment made to Marchese d'Adamo and his fellow workers who executed the cartoons of Sienese painters.
Right transept The right transept contains five sections of panels:
The Seven Ages of Man,
Religion and the Theological Virtues,
The Story of Jephthah,
The Death of Absalom, and
Emperor Sigismund.
The Seven Ages of Man is a collection of six octagonal panels surrounding a central rectangular panel and woven together by a geometric rope-inspired pattern. They depict the stages of life a man goes through, from infancy to death. The majority of the original work by
Antonio Federighi in 1457 was reconstructed in 1871.
Religion and the Theological Virtues is a set of panels, depicting an allegory of religion and three personifications of theological virtues (
Hope,
Faith, and
Charity). The original works from 1780 were replaced a century later by designs by
Alessandro Franchi.
The Story of Jephthah is credited to
Francesco di Giorgio Martini, and notably contains sixty characters throughout the panel. The finer details of the narrative have been lost over time.
The Death of Absalom by Pietro di Tommaso del Minella (1447) narrates a group of soldiers finding King David’s sin, Absalom, hanging dead from a tree. The figures are contrasted by a foreground of red marble, and a background of black marble. In 1434 the renowned painter
Domenico di Bartolo completed the panel
Emperor Sigismund Enthroned. The Holy Roman Emperor
Sigismund was popular in Siena, because he resided there for ten months on his way to Rome for his coronation.Today, the details are incredibly faded. == Works of art ==
