Renaissance art and architecture marked a pivotal shift in artistic expression. Artists embraced new techniques like linear perspective and oil painting, creating more realistic and vibrant works. This period saw a revival of classical themes and a focus on the human form, reflecting the humanist ideals of the time.

The Renaissance also transformed the role of artists in society. Wealthy patrons, including the Medici family and the Catholic Church, funded ambitious projects. This support allowed artists to experiment with innovative techniques and explore new subjects, leading to masterpieces that continue to captivate us today.

Artistic Innovations of the Renaissance

Advanced Painting Techniques

• Linear perspective created the illusion of three-dimensional space on a two-dimensional surface by using converging lines and a vanishing point
• Sfumato softened outlines and blended colors pioneered by Leonardo da Vinci (Mona Lisa) to create a more naturalistic appearance
• Chiaroscuro used strong contrasts between light and dark refined to add depth and drama to paintings (Caravaggio's works)
• Oil painting techniques perfected enabled artists to create more detailed and vibrant works with greater durability and layering effects
• Fresco painting evolved with innovations in preparation and application allowing for larger and more complex murals (Sistine Chapel ceiling)

Sculptural and Architectural Advancements

• Sculptural techniques advanced including the revival of lost-wax casting for creating intricate bronze sculptures
• Contrapposto poses developed giving sculptures a more natural and dynamic appearance (Michelangelo's David)
• Trompe l'oeil techniques created sophisticated optical illusions of three-dimensionality in both painting and architecture
• Architectural innovations incorporated classical elements and new engineering techniques for grander structures (Brunelleschi's dome of Florence Cathedral)

Humanism's Influence on Renaissance Art

Shift in Artistic Focus

• Humanism shifted art focus towards the individual leading to an increase in portraiture and secular subjects
• Classical Greek and Roman art and literature revived influencing artistic themes and architectural styles (Botticelli's Birth of Venus)
• Human form became a central subject of study resulting in more anatomically accurate and naturalistic depictions
• Emphasis on rational thought and empirical observation led artists to study nature and incorporate scientific principles into their work (Leonardo da Vinci's anatomical drawings)

Humanist Education and Artistic Expression

• Humanist education encouraged artists to become well-versed in multiple disciplines leading to the concept of the "Renaissance man" (Leonardo da Vinci, Michelangelo)
• Religious art began to incorporate more human elements depicting biblical figures with greater emotional depth and realism (Michelangelo's Pietà)
• Architectural designs reflected humanist ideals of harmony and proportion often incorporating classical elements and symmetry (Palazzo Rucellai in Florence)
• Artists began signing their works asserting their individual identity and creativity

Perspective and Proportionality in Renaissance Art

Mathematical Perspective Systems

• Linear perspective allowed artists to create more convincing illusions of depth and space in paintings and frescoes
• Brunelleschi's method provided artists with tools for precise spatial representation using a vanishing point and orthogonal lines
• Foreshortening techniques refined enabling more dynamic and realistic representations of figures in space (Mantegna's Dead Christ)
• Aerial perspective developed to create the illusion of distance through gradual changes in color and detail (Leonardo's landscapes)

Proportionality in Art and Architecture

• Proportionality in architecture based on classical ideals led to the creation of harmonious and balanced building designs (Palladio's villas)
• Golden ratio applied to compositions in both painting and architecture creating aesthetically pleasing arrangements
• Study of human proportions exemplified by works like Leonardo da Vinci's Vitruvian Man influenced figure drawing and sculpture
• Modular systems of proportion developed for architectural design ensuring harmony between parts and whole (Alberti's theories)

Art and Patronage in the Renaissance

Role of Patrons in Artistic Production

• Wealthy patrons including the Medici family in Florence played a crucial role in supporting artists and commissioning major works
• Catholic Church remained a significant patron funding large-scale projects (decoration of the Sistine Chapel)
• Patronage shifted from primarily religious institutions to include secular rulers wealthy merchants and private individuals
• Competition among patrons led to the creation of increasingly ambitious and innovative artworks (rivalry between Florence and Rome)

Changing Artist-Patron Relationships

• Artists gained higher social status through patronage with some forming close relationships with their benefactors (Michelangelo and Pope Julius II)
• Patrons often influenced the subject matter and style of artworks sometimes requesting specific themes or inclusions (family portraits in religious scenes)
• Rise of art markets and collecting practices among the wealthy contributed to the development of new genres and styles (still life, landscape)
• Artist workshops expanded to meet increased demand producing works for various patrons and markets
