Michelozzo di Bartolomeo Michelozzi (; – 7 October 1472), known mononymously as Michelozzo, was an Italian architect and sculptor. Considered one of the great pioneers of architecture during the Renaissance, Michelozzo was a favored Medici architect who was extensively employed by Cosimo de' Medici. He was a pupil of Lorenzo Ghiberti in his early years, and later collaborated with Donatello.
Known primarily for designing Palazzo Medici Riccardi in Florence, he is often overshadowed by his contemporaries Donatello in sculpture and Brunelleschi in architecture.
Life
Early life
Michelozzo was born in Florence in 1396. He was the son of Bartolomeo di Gherardo Borgognone and Antonia. Borgognone was of French origin and arrived in Florence from Burgundy at an unknown date. Borgognone lived and worked in the Santa Croce quarter of Florence as a tailor, and was made a Florentine citizen on 9 April 1376. Michelozzo had three brothers named Leonardo (b. 1389/90), Zanobi (b. 1391), and Giovanni (b. 1403). By 1391, Michelozzo's family had moved to the San Giovanni quarter, where they continued to live throughout his life.
Beginning in the early 1420s, Michelozzo became a member of the Arte dei Maestri di Pietra e Legname, one of the Guilds of Florence that represented the master stonemasons, wood-carvers, and sculptors. He later served as one of the consuls of the Guild in 1430.
Under Donatello, Michelozzo assisted in the building of the sacristy of Santa Trinita, where "Ghiberti [had] started to fuse together late-Gothic and antique forms." Both Donatello and Michelozzo began as sculptors with an uncompromising dedication to antiquity, and this was evident when Donatello enlisted Michelozzo's help in the decoration of the tabernacle of St. Louis of Toulouse. Michelozzo also became the partner responsible for the architectural frames of Donatello's sculptures such as the funerary monument of Antipope John XXIII. In 1428, together with Donatello, Michelozzo erected an open-air pulpit at an angle of the Cathedral of St. Stephen at Prato, designed for the regular public displays of their famous relic, the Girdle of Thomas (Sacra Cintola). Though Donatello is the more well-known of the two, "it would be a mistake to underrate Michelozzo's share in the work, for where Donatello appears as the sole designer of architectural ornament his style is quite different. He completely subordinates the architectural setting to his sculpture and makes architecture, so to speak, its handmaid. The beautiful ornamental sculpture in Brunelleschi's Sagrestia Vecchia shows how far Donatello would go with his sculpture in order to provide it with an effective frame in the extraordinarily vigorous modelling of the broad, slanting surrounds of his overdoors and medallions."
Michelozzo enjoyed a close relationship to Cosimo de' Medici throughout his life, and according to Giorgio Vasari in The Lives of the Most Excellent Painters, Sculptors, and Architects, from Cimabue to Our Times, was motivated by his great love and fidelity for Cosimo to accompany him into exile in Venice from 1433 to 1434. Historians have cited this as an unparalleled example of esteem between artist and patron. Vasari also claimed that Michelozzo built the library of San Giorgio Monastery in 1434 for Cosimo, though this claim contradicts the original description and documents of the library, which indicate that although the library's construction was started by Cosimo, it was largely built under the direction of Medici bank manager Giovanni d'Orino Lanfredini between 1467 and 1478, which was well after Michelozzo's departure from Venice.
The large Palazzo Medici in Florence, built by Cosimo, was designed by him; it is one of the noblest specimens of Italian fifteenth-century architecture, in which the great taste and skill of the architect has combined the delicate lightness of the earlier Italian Gothic with the massive stateliness of the classical style. With great engineering skill Michelozzo shored up, and partly rebuilt, the Palazzo Vecchio, then in a ruinous condition, and added to it many important rooms and staircases. When, in 1437, through Cosimo's liberality, the monastery of San Marco at Florence was handed over to the Dominicans of Fiesole, Michelozzo was employed to rebuild the domestic part and remodel the church. For Cosimo he designed numerous other buildings, most of them of noteworthy importance. Among these were a guest-house at Jerusalem for the use of Florentine pilgrims, Cosimo's summer villa at Careggi, and the fortified castello that he rebuilt from 1452 as the Villa Medicea di Cafaggiolo in Mugello. For Giovanni de' Medici, Cosimo's son, he also built a very large villa at Fiesole. Between 1445 and 1451, he also expanded Villa San Girolamo next to Villa Medici at the behest of Cosimo.
Filippo Brunelleschi
According to "Architecture in Italy, 1400–1500, Volume 53", Michelozzo's architecture contrasts with Brunelleschi in its closer adherence to the "immediately preceding Gothic tradition, the Gothic classicism which appears in the Loggia dei Lanzi or the monastery of S. Matteo." Ludwig Heydenreich and Paul Davies argue that all of Michelozzo's buildings are "works of considerable standing...the most independent architect after Brunelleschi."
In 1441, Michelozzo launched a legal complaint to remove himself from the responsibility of his two older brothers' debts. Andrea di Benozo, representative for Giovanni, Zanobi, and Michelozzo, elected arbitrators to weigh the complaints. After studying documents and proofs for six weeks, the arbitrators found that the two brothers were the cause behind most of Michelozzo's debts, and they were required to relinquish their inheritance in partial compensation for the amounts they owed.
Brunelleschi's influence on Michelozzo is evident in the palazzo's design, especially in the late-medieval bifora windows, the symmetry and the dominance of the entrance axis, and the combination of traditional and progressive elements. The arcades and entablature of the palazzo's courtyard also follows the model of the loggia of the Spedale degli Innocenti, which is symptomatically Brunelleschi's earliest and most un-Vitruvian building.
Michelozzo added various parts to the church and cloister of Santa Croce, including "the loggia in front of the Ex-Dormitory and Library (octagonal columns with foglie d'acqua capitals) which originally extended across the cloister to the elevated loggia on the south side of the church, running along the eastern flank of the San Giuliano (Mellini) Chapel...which divided the first cloister into two parts before its destruction in the nineteenth century."
Death and legacy

In spite of Vasari's statement that he died at the age of sixty-eight, he appears to have lived until 1472. He is buried in the monastery of San Marco, Florence.
One of the most influential, yet unknown, architects of the Early Renaissance, Michelozzo's designs paved the way for the rapid development of the Central Italian Palazzo type. He developed the aisleless church and became the pioneer of a plan-type of sacred building, which is the most important in modern times. He transformed secular building and his adaptability in use of traditional forms enabled him to evolve good compromise solutions for distant regions, such as Lombardy and Dalmatia.
In his careful treatment of architectural ornament, "Michelozzo was able to adopt ideas and turn them to good account as well as to transmit new ones. The styles of Manetti, Bernardo Rossellino, Giuliano da Maiano, and even of Giuliano da Sangallo are unimaginable without the support and influence of Michelozzo's artistic idiom in addition to that of Brunelleschi, and later, of Donatello."
