The High Renaissance

Achievement.

By the end of the fifteenth century Italian designers had developed a new sophisticated architectural language that relied on elements culled from the monuments and buildings of Antiquity. They had used this knowledge to create daring new structures that were unparalleled in the centuries that preceded the Renaissance. In Florence and other Italian cities, the new knowledge of classical style had also been used to create imposing urban palaces for wealthy families. For most of the fifteenth century architecture had been a craft largely practiced by sculptors, masons, and carpenters. Around 1500, though, painters began to design buildings with increasing frequency. Painters brought new skills to the practice of architecture, including a surer sense of draftsmen's skills acquired in their craft. They also used light and mass in building in bold new ways. Although none of his structures were ever built, Leonardo da Vinci's plans for several buildings point to the vibrancy of this new trend. Both his imagined designs as well as the writings and buildings of Alberti—all of which emphasized harmonious beauty and elegant refinement—were major influences on the development of High Renaissance architects. This period, which began around 1500 and ended abruptly with the Sack of Rome, produced many fine designs for buildings planned on an enormous scale. As in painting and sculpture, the High Renaissance in architecture produced new structures that were more heroic and grand than those of the fifteenth century. Unfortunately, the relatively slow progress of building construction doomed many of the High Renaissance's monumental architectural plans to incompletion. Some builders abandoned projects altogether; other builders truncated their projects or modified them to fit changing tastes. The High Renaissance in architecture, then, frequently presents us with a picture of great promises, but promises that were often left unfulfilled.

Shift to Rome.

Around 1500, the center of architectural innovation also shifted in Italy from Florence to Rome. The pace of construction in the city had already picked up during the second half of the fifteenth century, but with the election of Pope Julius II in 1503 a great period of expansion began. Julius was an impetuous and fiery personality. Known as the "Warrior Pope" he faced friends and foes alike with equal determination. Abroad, Julius marched into battle with his troops, pronounced public curses against his enemies, and beat recalcitrant cardinals who refused to march into battle with him with his cane. At home in Rome, he turned his steely will upon the face of the city, razing whole districts and rebuilding them to suit his desires for a grand capital. The tentative renewal plans of previous Renaissance popes paled in comparison with the building campaigns he waged during his ten-year pontificate. Julius called a host of artists to work in the city and refused to live in the papal apartments that had been recently refurbished by his predecessors. Instead he commissioned Raphael to provide him with new monumental frescoes that might equal the forcefulness of his personality. He hired Michelangelo to work on his enormous tomb, and then only a few years later, redirected the artist to painting the ceiling frescoes of the Sistine Chapel. His greatest endeavor of all, though, was his decision to rebuild St. Peter's Basilica, a structure originally constructed by the Roman emperor Constantine in the fourth century. To create the new church, which he stipulated must outshine every other church in Christendom, he demolished one of the largest surviving buildings from the ancient world. Summoning the architect Bramante, he soon began the greatest building project of the sixteenth century. Along the way to completion, the new St. Peter's Basilica consumed the efforts of the greatest architectural minds of the age, not to mention enormous sums of money. The project also lasted for more than 175 years, long beyond the scope of the pope's life. Before his death in 1513, Julius oversaw the partial destruction of the old basilica and the construction of the piers of the new building's crossing in order to commit future popes to follow through with his ambitious plans, even when those plans ran counter to the best interests of the church. During the reign of his immediate successor, Leo X (1513–1523), the demand for money to continue St. Peter's construction actually contributed to the great crisis of the Protestant Reformation when Leo arranged for the sale of an indulgence in Germany to finance the building's construction. Similar crises throughout the sixteenth century threatened the building's completion, although it was, and it remains, an indubitable testimony to Julius' initial inspiration.

Bramante.

Donato d'Agnolo, who was better known as Bramante, (1444–1514) became the chief aid to Julius in attaining his greatest architectural ambitions. A native of a small town near the central Italian city of Urbino, Bramante had a successful career as a painter before beginning to practice architecture in his forties. At that time he worked for the Sforza duke Lodovico il Moro and he designed several churches in their capital Milan. The architecture of Alberti (particularly in its use of Roman barrel vaults) and the architectural drawings of Leonardo, with their emphasis on the use of the central style and geometric shapes, both influenced Bramante's style. In 1499, French forces conquered Milan, however, and Bramante was left without employment. He traveled to Rome, where he soon found work because of his connections with the Sforza dynasty. In the city a member of the family, Ascanio Sforza, commissioned him to build his tomb, and over the following years Bramante designed and supervised the construction of a cloister in the city. In 1502, he created the small Tempietto, a memorial commissioned by King Ferdinand and Queen Isabella of Spain to mark the site upon which St. Peter supposedly had been crucified. This small domed structure, considered one of the finest of High Renaissance architectural creations, perfects the central style of construction to a point of high finesse. Everything in the small building radiates outward from the memorial's center point, and shows that Bramante had now taken full advantage of his recent viewing of ancient Roman monuments firsthand. Although more severe than the architect's earlier designs, the work points forward toward his plans for the new Basilica of St. Peter's, a commission he won in 1506.

St. Peter's.

For that great construction project the artist may have considered several possible plans, although he settled eventually on a central-style church, created in the shape of a Greek cross. The architectural drawings of Leonardo da Vinci, which Bramante had studied years before in Milan, influenced his plans for a building constructed as a Greek cross in which each of the church's four radiating wings were of exactly equal size. Eventually, the church's later architects abandoned the Greek cross in favor of a more traditional Latin cross design in which the nave was longer than the other three wings. Bramante's plan, however, called for each of the four corners of the building to be crowned with a large tower, and a dome—envisioned from the very first—was to sit atop the central crossing. Inside the structure Roman barrel vaults, drawn from the architecture of Alberti, were to cover each of the wings, a design feature that was also later achieved. The dome Bramante designed was innovative by Renaissance standards, and shows his growing mastery of the architectural forms of Antiquity. Until Bramante's time architects had relied on the ribbed-style dome first used by Brunelleschi at the cathedral of Florence. In that structure, floating ribs of stone had supported panels of masonry. Bramante's plans for the new St. Peter's stipulated a circular structure, an exact hemisphere based upon the still-standing ancient Pantheon in Rome. To give the dome's unusual shape greater height, Bramante placed the structure atop a drum, a structure that was one of the Renaissance's chief design innovations in constructions of this nature. In sum, the plans Bramante crafted for the new St. Peter's were monumental, and befit the enormous ambitions of the "Warrior Pope" Julius II. At the same time the design was too large to be completed in a single person's lifetime. At the time of Julius' death only the eastern portion of the ancient Roman structure at the site had been cleared away. Many of the features of Bramante's design never came to fruition, including his plans for a perfectly hemispherical dome and other elements of his interior and exterior plans for the church. The imaginative design that he envisioned can best be seen not in Rome but in the small central Italian town of Todi. Here in 1508 Bramante designed the much smaller Santa Maria della Consolazione, a small pilgrimage church, which made use of the ideas he was developing for the new St. Peter's around the same time. The building sits on a small plain and is not surrounded by any other structures, a site that provides an excellent vantage point to observe the harmonious aspects of its design. Like many of Bramante's other plans, the structure functions organically, almost as if it were a sculptural, rather than an architectural creation. It is here that one can observe the Renaissance's desire to develop an architecture based upon the design principles of the human form.

A PAPAL ARCHITECT

introduction: The architect and painter Giorgio Vasari wrote a famous series of biographies of Italy's greatest artists, which were first published in 1550. In his life of Bramante, Vasari carefully catalogues the changes that were made up to his day in the architect's plans for the new St. Peter's Basilica. The following excerpt illustrates the dangers of later alteration, to which most of the great architectural projects of the High Renaissance fell prey. By Vasari's time, Michelangelo, then the papal architect, was at work to restore key elements of Bramante's original design.

But the work we are here alluding to was conducted after a much altered fashion on his death and by succeeding architects; nay, to so great an extent was this the case, that with the exception of the four piers by which the cupola is supported we may safely affirm that nothing of what was originally intended by Bramante now remains. For in the first place, Raffaelo da Urbino and Giuliano da San Gallo, who were appointed after the death of Julius II to continue the work with the assistance of Fra Giocondo of Verona, began at once to make alterations in the plans; and on the death of these masters, Baldassare Peruzzi also affected changes when he constructed the chapel of the king of France in the transept which is on the side towards the Campo Santo. Under Paul III the whole work was altered once more by Antonio da San Gallo, and after him Michael Angelo, setting aside all these varying opinions, and reducing the superfluous expense, has given the building a degree of beauty and perfection, of which no previous successor to Bramante had ever formed the idea; the whole has indeed been conducted according to his plans, and under the guidance of his judgment, although he has many times remarked to me that he was but executing the design and arrangements of Bramante, seeing that the master who first founded a great edifice is he who ought to be regarded as its author. The plan of Bramante in this building does indeed appear to have been of almost inconceivable vastness and the commencement which he gave to his work was of commensurate extent and grandeur; but if he had begun this stupendous and magnificent edifice on a smaller scale, it is certain that neither San Gallo nor the other masters, not even Michael Angelo himself, would have been found equal to the task of rendering it more imposing, although they proved themselves to be abundantly capable of diminishing the work: for the original plan of Bramante indeed had a view to even much greater things.

Other Projects.

Even as he was at work upon the designs for the new St. Peter's, Julius II deployed Bramante to plan other projects. One of these was the rebuilding of the Vatican Palace. Julius wished to join two structures—the small hilltop house known as the Belvedere and the Vatican Palace—which stood more than an eighth of a mile apart across undulating terrain. Bramante planned two enormous corridors that were more than a thousand feet long and two hundred feet wide. These corridors enclosed three garden terraces filled with fountains and grand staircases designed to follow the rolling shape of the site's hills. The scale of the project was immense, and like many of Bramante's buildings it was left unfinished at his death. Subsequent alterations changed the face of those parts of the work that Bramante designed, destroying the grand vistas that the architect had envisioned for the Vatican complex. Not until Louis XIV's building program at Versailles in the seventeenth century, though, did another monarch attempt anything quite so grand as Bramante's design, and the partial realization of the surviving plans for the gardens of the complex influenced garden planning for several centuries to come. A similarly important work from the architect's later years in Rome was his design for the Palazzo Caprini, a structure that is sometimes referred to as the House of Raphael, since the artist purchased it in 1517. In that building Bramante made full use of the concept of a screen or decorative façade filled with classical elements that masked the building's underlying structural elements. The ground floor of this structure was heavily rusticated and contained a succession of Roman arches. Above this, the living quarters featured decorative balustrades and grouped columns that supported a classical cornice. None of these elements played a structural role, but were design touches that evoked Roman Antiquity and granted an air of refinement to the building. The elegance of the design (the house itself has long since been demolished) affected later architects, including the Venetian Andrea Palladio. Palladio so admired Bramante's Roman buildings that he observed that the artist had single-handedly brought "the light of architecture" back into the world. This hyperbole was far from correct, since a number of great and innovative designers had preceded Bramante. Nevertheless, his grand Roman designs instituted and continued to shape architecture in the style of the High Renaissance throughout the sixteenth century.

Domestic Building.

The first decades of the sixteenth century witnessed a dramatic surge in the building of great urban palaces and suburban villas for Rome's wealthiest citizens and foreign dignitaries. This boom, similar to the great construction bonanza that occurred in fifteenth-century Florence, resulted in the erection of a number of new and innovative domestic structures. The finest painters and architects of the age worked on these projects, including Raphael, Baldassare Peruzzi, Antonio da Sangallo the Younger, and Giulio Romano. By contrast to the solidity and weight of most Florentine palaces of the previous century, an elegant refinement characterized these Roman structures. In the years after Bramante's death in 1514, Raphael entered the arena of Roman architecture. He became director of the construction of St. Peter's Basilica, a project on which he accomplished little since the building program slowed in the years after 1515 because of lack of funds. His most ambitious design program, outside of his involvement in the great basilica, was the construction of the Medici Villa or, as it is now known, the Villa Madama, a large suburban house near the Vatican intended for the use of Cardinal Giulio de' Medici. Raphael designed the structure with a number of intriguing and fantastic details, including circular courtyards and domed ceilings. He made use of the sloping hillside site and planned to set the villa within a series of delightful gardens. As in the case of many ambitious Renaissance projects of this nature, circumstances forced Giulio de' Medici to divert his attentions from the project, and little of Raphael's ambitious design saw completion. One section of the villa, the Great Hall, still stands today, allowing us to observe Raphael's skills as an architect. He designed the room with a series of arches that supported a dome; the room's arches also frame the exterior gardens. Both the interior and exterior space thus work as part of a harmonious whole; later sixteenth-century architects imitated Raphael's design at the Villa Madama.

ASSESSING ANCIENT ROME

introduction: With the death of Bramante, Pope Leo X appointed Raphael to serve as his chief architect. One of the tasks given to the artist was to complete a survey of the surviving ancient monuments in Rome. Raphael was a poor writer, so it appears that he wrote his report with the aid of his friend, Baldassare Castiglione. Castiglione was the author of the Book of the Courtier, one of the greatest prose works in sixteenth-century Italian. The following excerpt from the report shows the deep feelings of wonder that ancient architecture inspired in Raphael, and he laments the decay of the city.

For, if one considers what may still be seen amid the ruins of Rome, and what divine gifts there dwelt in the hearts of the men of ancient times, it does not seem unreasonable to believe that many things which to us would appear to be impossible were simple for them. Now I have given much study to these ancient edifices: I have taken no small effort to look them over with care and to measure them with diligence. I have read the best authors of that age and compared what they had written with the works which they described, and I can therefore say that I have acquired at least some knowledge of the ancient architecture.

On the one hand, this knowledge of so many excellent things has given me the greatest pleasure: on the other hand the greatest grief. For I behold this noble city, which was the queen of the world, so wretchedly wounded as to be almost a corpse. Therefore I feel, as every man must feel, pity for his kindred and for his country. I feel constrained to use every part of my poor strength to bring to life some likeness, or even a shade of that which once was the true and universal fatherland of all Christians …

May your Holiness, while keeping the example of the ancient world still alive among us, hasten to equal and to surpass the men of ancient days, as you even now do, by setting up magnificent buildings, by sustaining and encouraging the virtuous, by fostering talent, by rewarding all noble effort—thus sowing the fruitful seeds among the Christian princes. For, as by the calamities of war are brought to birth the destruction and the ruin of the arts and sciences, so from peace and concord are born the happiness of men and that highly-prized serenity of spirit that may imbue us with strength to accomplish work reaching to the heights of achievement.

Sangallo.

Another domestic project from the early sixteenth century merits mention. In 1517, the influential Cardinal Alessandro Farnese commissioned Antonio da Sangallo the Younger to remodel a palace he had bought in Rome. Sangallo, a member of the Florentine dynasty of builders and designers, had originally served as a carpenter at the building of St. Peter's Basilica in Rome. The majestic structure he crafted for Farnese established Sangallo's reputation; he received numerous commissions and even served as the chief architect of St. Peter's during the years between 1539 and 1546. The architect planned a huge masonry palace for the cardinal that abandoned the long-standing use of rusticated stone on its façade. Rough stone appears only at the arches that grant entrance into the building's massive interior courtyard. On the first floor he used low-rising windows, similar to ones that Michelangelo had designed to be installed a few years before on the façade of the Medici Palace in Florence. On the story above he relied on the Corinthian columns to frame the windows, which are alternately topped by rounded and triangulated pediments. Above on the structure's final floor, he mixed elements from the lower two floors before capping the entire structure with a cornice. Michelangelo, who supervised the later years of the building's long construction period, made this element grander and more prominent. The Palazzo Farnese was a huge building, massive in size, severe, yet refined in its effect. It influenced the design of many public and private buildings in European cities for years to come. The Palazzo Farnese also shaped American architecture. With the Renaissance architectural revival that occurred in North America in the late nineteenth century, numerous buildings resembling Italian palaces appeared in American cities. The style of the Farnese became popular. Perhaps it is for this reason that, in 1944, the United States purchased the Palazzo Margherita, another palace closely constructed upon the model of the Farnese, to serve as its embassy in Rome.

Pleasure Palaces.

The sixteenth century in Rome also produced a spate of pleasure palaces, buildings designed as retreats for their owners and as the backdrop for impressive banquets and other entertainments. The artist Raphael, who had already designed the suburban Villa Madama, also played a role in the decoration of one of these projects, a pleasure palace constructed for Agostino Chigi, the pope's banker. This structure is now known as the Villa Farnesina (since the Farnese family later bought it and connected it to their town Palazzo by a suspended walkway). Originally, the villa stood in a quiet country setting on the outskirts of the city. Chigi chose Baldassare Peruzzi as the project's architect. The building has two stories with a large façade of Roman arches in the center facing the surrounding gardens. Originally, delicate ornamentation carved into the stucco plaster or intonaco decorated the façade. Today, these decorative details survive only on the building's frieze, the others having been covered up since the sixteenth century. The delicacy of these decorations suggested the building's role as a pleasure palace, a building intended for the amusement of Chigi, his wife, and their guests, as opposed to a dwelling. The villa had only a few major rooms, but these were sumptuously decorated and used to entertain. At Chigi's banquets, guests were said to have imitated the customs of ancient Rome by throwing their gold plates out the villa's windows (although Chigi's servants soon reclaimed them below). The interior walls of the villa were filled with ornate and sumptuous decorative cycles painted by Peruzzi, Raphael, and other artists in a style that imitated ancient Roman frescoes. The illusionistic details of the frescoes suggested the architecture of ancient Rome, and their erotic and classical imagery impressed Chigi's guests not only with the size of his fortune but the depth of his learning. The example of Chigi's pleasure villa inspired other members of Italy's ruling classes to build similar structures in the decades that followed.

Michelangelo.

The artist Michelangelo had the longest and most varied career of any figure of the Renaissance. He lived until 1464 and his art underwent a progression from the idealized, heroic forms of the High Renaissance to the more willful and turbulent creations that inspired Italian Mannerism. As the greatest artistic genius of the age, his development affected other figures who avidly imitated his design innovations. Originally trained as a painter in the studio of the prosperous Florentine artist Domenico Ghirlandaio, Michelangelo also studied sculpture, and throughout his life he felt most at home in this medium. It was as a sculptor that the artist made his first decisive marks on Renaissance art. The carving of his Roman statues Bacchus and the Pietà established his reputation. Following these masterpieces, Michelangelo returned to Florence to complete, among many other works, his colossal David, the largest free-standing statue since Antiquity. Michelangelo continued to work in Florence, but with the accession of Julius II to the papacy, he was soon called to Rome to work on the pope's tomb project. The plans for the Julian tomb called for a massive independent structure that would contain scores of sculptures, architectural niches, and a bronze frieze. The tomb was never completed on this ambitious scale and it took more than thirty years for a greatly scaled-down memorial to be finished. But in the years between 1505–1508, Michelangelo was at work on the project, and from these initial experiences he began to acquire the skills necessary to be a successful architect and project supervisor. The tomb project required the quarrying of enormous amounts of marble and the supervision of large work crews. Although Michelangelo worked on the project for several years full time, Julius II soon moved him to work on the famous Sistine Chapel ceiling frescoes, a commission he completed in the years between 1508 and 1512. The election of the Medici pope Leo X in 1513 confirmed Michelangelo's papal patronage, and by 1517 the artist was back in Florence, undertaking an important project for the pope: the construction of a new façade for the Medici's family church of San Lorenzo. During the fifteenth century the family had richly showered this site with patronage. By the time that Michelangelo worked there, the Medici had weathered several challenges to their control over Florence and they had now allied themselves through marriage to the kings of France. The family now turned again to San Lorenzo, to shower it with new projects that underscored their rising status. Just before Michelangelo had arrived in Florence the venerable architect Giuliano da Sangallo, the uncle of the Roman architect Antonio, had made several drawings for plans for the project, although he had died before progressing further on the project. One of Sangallo's designs created an imaginative solution to the problem of the façade. Sangallo created a two-story Roman temple flanked by enormous towers to hide certain of the unattractive exterior elements of Brunelleschi's original design. In this drawing he planned to mass classically-styled sculptures of the saints atop the façade's upper story, in effect creating a screen similar to that with which Baldassare Peruzzi was experimenting in Rome at the Palazzo Caprini around the same time.

San Lorenzo.

The Medici chose Michelangelo's plan for the church's façade instead. In keeping with the grand pretensions of the church's patron family, Michelangelo intended his design to be a "mirror of architecture and sculpture of all Italy" and he labored on the plans for over three years. The design he formulated was also for a two-story structure, although Michelangelo designed his structure without towers to cover the entire area of the church's edifice. Like the earlier project for the building of Julius' tomb, the San Lorenzo project was overly ambitious; it included eighteen statues in bronze and marble as well as fifteen carved reliefs. A surviving model of the façade shows shallow niches, from which the planned statues were to have projected outward. The use of marbles and bronze together would have created a dramatic interplay of color. Michelangelo set himself to the task quickly, supervising the quarrying of stone, a project that eventually required him to build a road through a portion of the Apennine Mountains outside Florence. But although the artist worked feverishly on the project for several years, the Medici cancelled the commission for the façade abruptly in 1520, deciding to expend the family's resources on a chapel and family tomb at the church instead. They chose Michelangelo again to direct this commission, and the chapel he designed was made to harmonize with a sacristy Brunelleschi had built for the opposing side of the church in the fifteenth century. Work was frequently interrupted on the tombs, and the chapel was never finished as it had been designed. But among Michelangelo's architectural creations it ranks as one of his most completely realized creations. To secure better lighting for the tombs, Michelangelo raised the roof of the chapel by adding a third story that brought the structure's roofline above those of surrounding houses. In other respects he relied on the traditions of Brunelleschian architecture, including the use of gray pietra serena set against white stucco. In this structure Michelangelo's carved tombs, with their more delicate and refined High Renaissance architectural frames, seem out of place with the surrounding fifteenth-century style of the chapel.

Laurentian Library.

Michelangelo was soon to develop a more unified style, one that was notable for its willful violations of the traditional canons of classical design. In 1524 the Medici pope Clement VII (r. 1523–1534) awarded the artist the commission to design a new library for San Lorenzo. This site was intended from the first to be dedicated to the use of humanist scholars and was to house the Medici's large collection of rare manuscripts. Michelangelo planned an entire complex at the site, including an Entrance Hall, Reading Room, and a rare-book chamber, although he never lived to see the structure completed. The site itself was problematic since it was irregularly shaped, and the building had to be made to fit overtop and in between other structures that already stood on the church's grounds. Michelangelo's design solved these problems brilliantly, although the building was not executed completely in the manner in which he had planned. He designed a stately entrance to the library with a high staircase set in an imaginative architecture that bent the rules of traditional classical design. Michelangelo lined the walls of these spaces with pilasters that appear to support the ceiling, but which are instead set in niches, so that on second glance they appear like mere decorative sculptures that taper as they move downward. Below these niches the architect placed classical stone scrolls that again serve, not as traditional supports, but as mere sculptural or decorative elements placed on the walls. The effect of these design elements seems to make the room cave inward, although other features counteract this effect. The architect, for instance, divided the large staircase—the focal point of the room—into three sections and he bowed the stairs of the central section outward in a bold hemispherical shape. These hemispheres wage battle against the downward tapering pilasters that are placed within the wall's niches. Once above within the Reading Room the first impression is at once more traditional. The columns that line the room actually appear to support the ceiling, and its other elements seem to be drawn from a traditional classical architectural language. On closer inspection, though, Michelangelo seems to repeat the elements of the room's design ad infinitum, so that the windows and transepts that are above them, as well as the endless rows of reading desks and the patterned floor, take on the same dimension of a Herculean struggle as occurred outside in the entry hall. One appears, for instance, to be caught in a cage in which the room's design elements are constantly being repeated without relief. Unfortunately, the last element of Michelangelo's Laurentian Library design was never built. The architect had planned a final culmination to the architectural battle he had presented in the library's first two spaces: a dramatic triangular-shaped rare-book room designed to fit inside the spaces between buildings on the library's exterior. This conclusion to the Laurentian Library's strange and challenging architecture might have presented one of the most unusual spatial solutions of the Renaissance. But like many architectural plans of the period it was not constructed when the patron's interests shifted elsewhere.

Changing Tastes.

The Laurentian Library reveals a new taste for creative experimentation, a taste shaped by artist and patron alike. As the High Renaissance period drew to its conclusion at the end of the first quarter of the sixteenth century, architectural design came to be affected by changes similar to those underway in painting, sculpture, and literature. During the course of the fifteenth century architects had fastidiously studied classical Antiquity, and in the High Renaissance had achieved a mastery over ancient styles that allowed them to produce designs and structures notable for their complete assimilation of classicism. These details had been used to grant a human scale to projects that were heroic and monumental in nature. In his Laurentian Library complex Michelangelo showed a new direction, and the structure influenced later architects who used the language of classical Antiquity in a boldly willful and creative way. The violations of the canons of ancient design that Michelangelo displayed at the Laurentian were intentional, and they helped to give rise to the new movement in Renaissance architecture known as Mannerism.
