__***What are the cultural and historical backgrounds of Italian Renaissance art and architecture?***__
By the end of the Middle Ages, the most important Italian cultural centers lay north of Rome in the cities of Florence, Milan, and Venice, and in the smaller court cities of Mantua, Ferrara, and Urbino. Political power and artistic patronage were both dominated by wealthy families: the Medici in Florence, the Montefeltro in Urbino, the Gonzaga in Mantua, the Visconti and Sforza in Milan, and the Este in Ferrara (MAP 20–1). Cities grew in wealth and independence as people migrated from the countryside in unprecedented numbers. Like in northern Europe, commerce became increasingly important. Money conferred status, and a shrewd business or political leader could become very powerful. The period saw the rise of mercenary armies led by entrepreneurial (and sometimes brilliant) military commanders called condottieri, who owed allegiance only to those who paid them well; their employer might be a city-state, a lord, or even the pope. Some condottieri, like Niccolò da Tolentino (SEE FIG. 20–1), became rich and famous. Others, like Federico da Montefeltro (SEE FIG. 20–39), were lords or dukes themselves, with territories of their own in need of protection. Patronage of the arts was an important public activity with political overtones. As one Florentine merchant, Giovanni Rucellai, succinctly noted, he supported the arts “because they serve the glory of God, the honour of the city, and the commemoration of myself” (cited in Baxandall, p. 2). The term Renaissance (French for “rebirth”) was only applied to this period by later historians. However, its origins lie in the thought of Petrarch and other fourteenth-century Italian writers, who emphasized the power and potential of human beings for great individual accomplishment. These Italian humanists also looked back at the thousand years extending from the disintegration of the Western Roman Empire to their own day and determined that the achievements of the Classical world were followed by what they perceived as a period of decline—a “middle” or “dark” age. They proudly saw their own era as a third age characterized by a revival or rebirth (“renaissance”), when humanity began to emerge from what they erroneously saw as intellectual and cultural stagnation to appreciate once more the achievement of the ancients and the value of rational, scientific investigation. They looked to the accomplishments of the Classical past for inspiration and instruction, and in Italy this centered on the heritage of ancient Rome. They sought the physical and literary records of the ancient world—assembling libraries, collecting sculpture and fragments of architecture, and beginning archaeological investigations. Their aim was to live a rich, noble, and productive life—usually within the framework of Christianity, but always adhering to a school of philosophy as a moral basis. Artists, like the humanists, turned to Classical antiquity for inspiration, emulating ancient Roman sculpture and architecture even as they continued to fulfill commissions for predominantly Christian subjects and buildings. But a number of home furnishings from the secular world, such as birth trays and marriage chests, have survived, richly painted with allegorical and mythological themes. Patrons began to collect art for their personal enjoyment. Like Flemish artists, Italian painters and sculptors increasingly focused their attention on rendering the illusion of physical reality. They did so in a more analytical way than the northerners. Rather than seeking to describe the visual appearance of nature through luminosity and detailed textural differentiation, Italian artists aimed at achieving lifelike but idealized weighty figures set in a space organized through strict adherence to linear perspective, a mathematical system that gave the illusion of a measured and continuously receding space (see “Renaissance Perspective” on page 623).
