Guidoccio Cozzarelli's greatness derives from eclecticism and the spirit of humanity that saturate his paintings. Cozzarelli's historical works possess a passionate exuberance, bursting with dramatic details. His energetic style generated steady lucrative commissions throughout his painting career. He is considered one the greatest Renaissance painters of all time.
The newly emerging painting techniques and styles were a reflection of the transformation that was taking place in Europe, the change from the medieval period to a more enlightened, tolerant society. According to Historian Hendrik van Loon, "People were tremendously alive. Great states were being founded. Large centres of commerce were being developed. High above the turreted towers of the castle and the peaked roof of the town-hall, rose the slender spire of the newly built Gothic cathedral. Everywhere the world was in motion. The high and mighty gentlemen of the city-hall, who had just become conscious of their own strength (by way of their recently acquired riches) were struggling for more power with their feudal masters.

This painting depicts the girls swimming across the Tiber in the center and arriving at the gate of Rome on the right. At the left Publicola returns them to the Etruscan camp and Cloelia kneels before Porsena.

Biccherne are painted biccherna tablets, originally book covers of the ledgers of the biccherna and gabella, the financial and fiscal offices of the commune of Siena.
Almost all the Sienese Renaissance artists ventured on painting the wooden panels, precious like miniatures and very often characterized by the representation of the main events of Sienese history. Sano di Pietro was commissioned more than once to celebrate contemporary people and their noble achievements (in 1457, in 1471, in 1473); Vecchietta depicted the Coronation of Pope Pius II Piccolomini in the biccherna of 1460; Francesco di Giorgio recalled the earthquake in the biccherna of 1467; Neroccio was entrusted with the Intercession of the Virgin Mary to Jesus for the town of Siena and Guidoccio Cozzarelli depicted the scene of the Presentation of the Virgin in the Temple, so skillfully that considering he was confined to the small surface of the tablet the result is with no doubt equal to any of his altarpieces.

The panel The Virgin guiding “the ship of the Republic” refers to the return to Siena of the magistracy of the Nine lead by Pandolfo Petrucci, who later became Siena’s ruler, as a welcome change occurred under the Virgin’s protection. Traditionally attributed to Guidoccio Cozzarelli it was presented at the National Gallery exhibition in London as a work of Guidoccio’s master Matteo di Giovanni.

Piazza del Duomo is dominated by the imposing structure of Siena’s cathedral, dedicated to Santa Maria Assunta. The building stands over an existing church that in turn was built over a pagan temple dedicated to the goddess Minerva. Construction of the existing Duomo started in 1200, with the main sections already completed by 1215. The dome was built between 1259 and 1264.

The Latin cross design of the church includes three naves and is entirely sheathed in strips of alternating black and white marble, a reference to the black and white colours of the coat of arms of the city of Siena.

Six sided at its base, the cupola develops into twelve sides as it rises and is adorned with gilded statues of saints placed in the niches at its base. The asymmetrical canopy above is decorated with 42 figures of the patriarchs and prophets, painted at the end of the 15th century. In 1532 Baldassare Petruzzi completed the marble high altar, which is surmounted by a bronze tabernacle by Vecchietta (1467-1472). The vast stained glass window of the apse is by Duccio di Buoninsegna.
