The Palazzo Medici, also called the Palazzo Medici Riccardi after the later family that acquired and expanded it, is a Renaissance palace in Florence.The palace was designed by Michelozzo di Bartolomeo for Cosimo de' Medici, head of the Medici banking family, and was built between 1444 and 1484. It was well known for its stone masonry includes rustication and ashlar. The tripartite elevation used here expresses the Renaissance spirit of rationality, order, and classicism on human scale. This tripartite division is emphasized by horizontal stringcourses that divide the building into stories of decreasing height. The transition from the rusticated masonry of the ground floor to the more delicately refined stonework of the third floor makes the building seem lighter and taller as the eye moves upward to the massive cornice that caps and clearly defines the building's outline.Michelozzo di Bartolomeo was influenced in his building of this palace by both classical Roman and Brunelleschian principles. During the Renaissance revival of classical culture, ancient Roman elements were often replicated in architecture, both built and imagined in paintings. In the Palazzo Medici Riccardi, the rusticated masonry and the cornice had precedents in Roman practice, yet in totality it looks distinctly Florentine, unlike any known Roman building.Similarly, the early Renaissance architect Brunelleschi used Roman techniques and influenced Michelozzo. The open colonnaded court that is the center of the palazzo plan has roots in the cloisters that developed from Roman peristyles. The once open corner loggia and shop fronts facing the street were walled in during the 16th century. They were replaced by Michelangelo's unusual ground-floor "kneeling windows" (finestre inginocchiate) with exaggerated scrolling consoles appearing to support the sill and framed in a pedimented aedicule a motif repeated in his new main doorway.{Citation needed|date=August 2012} The new windows are set into what appears to be a walled infill of the original arched opening, a Mannerist expression Michelangelo and others used repeatedly.The building reflects the accumulated wealth of the Medici family. The fifteen-year-old Galeazzo Maria Sforza was entertained in Florence in 17 April 1459, and left a letter describing, perhaps in the accomplished terms of a secretary, the all-but-complete palazzo, where his whole entourage was nobly accommodated.Cosimo received the young Sforza in the chapel "not less ornate and handsome than the rest of the house". The building still includes, as its only 15th century interior that is largely intact, the Magi Chapel, frescoed by Benozzo Gozzoli, who completed it in 1459 with a wealth of anecdotal detail of character types traditionally held to be portraits of members of the Medici family, along with the emperors John VIII Palaiologos and the Emperor Sigismund of Luxemburg, parading through Tuscany in the guise of the Three Wise Men. Other decorations included two lunettes by Filippo Lippi, depicting Seven Saints and the Annunciation, now at the National Gallery, London.When the Medici family returned to Florence after their short-lived exile in the early 15th century, they kept a low profile and executed their power behind the scenes. This is reflected in the plain exterior of this building, and is said to be the reason why Cosimo de' Medici rejected Brunelleschi's earlier proposal. The palace was the site of the wedding reception between Ferdinando de' Medici, Grand Prince of Tuscany and Violante Beatrice of Bavaria in 1689.
