Santo Spirito, Florence. The Basilica di Santo Spirito is a church in Florence, Italy. Usually referred to simply as Santo Spirito, it is located in the Oltrarno quarter, facing the square with the same name. The interior of the building-internal length 97 meters-is one of the preeminent examples of Renaissance architecture. The land for the Augustinian church and convent was donated by Speziale and Acolti to Aldebrandino, a prior of the Augustinian establishment in Arcetri in 1250. The plot was located on the south bank of Arno in the sesto Oltrarno, within the communal walls of 1173-1175, but in a sparsely populated area. It became more accessible with construction of the Holy Trinity bridge in 1252. The Augustinians started the church and the convent in the same year, incorporating an old church of San Romolo in the complex. It was originally dedicated to Mary, All Saints and the Holy Spirit, changing by the end of the century to Mary, the Holy Spirit and Matthew. The churches and convents of mendicant orders were constructed with the financial support of the commune, which provided funds for Santo Spirito in 1267, and then from 1292 to 1301. The convent of S. Spirito became a center of scholarly activities and was recognized as Studium Generale of the Augustinian order in 1284. The first Rule and Constitutions of the Augustinians were approved in 1287 by the general chapter of the order that was held in Florence. Houses were purchased in 1301 to produce a public square in front of the church, the Piazza Santo Spirito. By 131Santo Spirito had seven altars and a number of family chapels. More chapels were built during the next hundred years. By mid-century Santo Spirito was a very substantial complex, including a large first cloister. Frescoes Crucifixion and The Last Supper were painted by Andrea Orcagna and his workshop in the 1360s. The confraternity of Santa Maria delle Laude, dedicated to the Virgin Mary and her praise was founded before 1322. It was staging an annual Pentecost play celebrating the descent of the Holy Spirit to the Apostles. It also was involved in charity: friar Simone Fidati da Cascia directed the laudese foundation of a house for former prostitutes. In 1333 it already housed more than fifty women. Santo Spirito was associated with the early humanism in Florence. One of the groups, led by Bocaccio, gathered there in 1360s and 1370s. Upon his death in 1375 Bocaccio bequeathed his library to the convent.In the 1380s and early 1390s another circle of humanists met daily in the cell of Luigi Marsili. Marsili had studied philosophy and theology at the Universities of Padua and Paris. He came into contact with Petrarch at Padua in 1370 and later became a friend of Bocaccio. This group included Coluccio Salutati, Chancellor of Florence from 1375. He soon became the central figure of the circle.The most important of Salutati disciples was Leonardo Bruni, the future Chancellor of Florence. Another member of the circle was Niccolo de' Niccoli, a humanist and an associate of Cosimo Medici. Santo Spirito was a scene of several dramatic events during the period of political instability of 1370s.As the only area of the city located across the Arno, the sieste of Santo Spirito was physically and politically apart from the rest of Florence. Among its inhabitants were some of the most prominent and ancient families of the city, such as the Capponi, the Soderini, and Frescobaldi, as well as some of the poorest unskilled laborers. This politically explosive mix gave to the quarter its image of one of the most ready to rebel.One of the most sensational political assassinations in the history of the Republic of Florence was a murder of Sandro da Quarata, a prominent member of the Ricci faction, in November 1370, when he was exiting the church after mass.In the lead up-to the Ciompi revolt the monastery was attacked by rioters on 22 June 1378, but defended by the forces loyal to signoria. Interrogations of the conspirators arrested on 19 July, indicate the planned revolt was to be staged in four separate rising, with the largest in the church of S. Spirito. After the Florentine victory over the Milanese in 1397 during the second Milan war on the feast day of Saint Augustine, the signoria decided to rebuild the church to honor the saint, placing it under the patronage of the city.Despite this decision, nothing much happened until 1434, when the operai retained the services of Filippo Brunelleschi. Work on the new church progressed slowly until March 1471. During the Descend of the Holy Spirit sacra rappresentazione organized by the laudese in honor of the visit of Galeazzo Maria Sforza the old church caught fire and was heavily damaged, together with parts of the convent.
