Final answer:
The primary goal of most Renaissance artists was to (a) imitate classical styles, emphasizing realism and perspective to depict human form and space in a way that revived ideals of classical antiquity.
Step-by-step explanation:
The primary goal of most Renaissance artists was a) Imitating classical styles. Artists during the Early Renaissance aimed to revive the classical antiquity ideals including harmony, balance, and realism. This aim was partly propelled by the rejection of the Byzantine style of religious paintings in favor of a more realistic depiction of the human form and space. This realism in art was achieved through the introduction of techniques like linear perspective which created the illusion of three-dimensional space on a flat surface.
Renaissance artists such as Andrea Mantegna and Paolo Uccello mastered the technique of one point perspective, leading to works that celebrated the educated viewpoint of their time. The realistic representation of human forms by these artists, and others like Leonardo da Vinci, Michelangelo, and Sandro Botticelli, firmly established them within the vibrant culture of realism in paintings. The movement away from religious orthodoxy, medieval styles, and abstract expressionism, was a defining characteristic of Renaissance art, underlining the artists' devotion to re-embracing classical antiquity's aesthetics.
