Religious Islamic art forbids iconography, and instead expresses religious ideas through calligraphy and geometrical designs. Classifications In the Middle Ages, the Artes Liberales (liberal arts) were taught in European universities as part of the Trivium, an introductory curriculum involving grammar, rhetoric, and logic, and of the Quadrivium, a curriculum involving the "mathematical arts" of arithmetic, geometry, music, and astronomy. The Artes Mechanicae (consisting of vestiaria – tailoring and weaving; agricultura – agriculture; architectura – architecture and masonry; militia and venatoria – warfare, hunting, military education, and the martial arts; mercatura – trade; coquinaria – cooking; and metallaria – blacksmithing and metallurgy) were practised and developed in guild environments. The modern distinction between "artistic" and "non-artistic" skills did not develop until the Renaissance. In modern academia, the arts are usually grouped with or as a subset of the humanities. Some subjects in the humanities are history, linguistics, literature, theology, philosophy, and logic. The arts have also been classified as seven: painting, architecture, sculpture, literature, music, performing and cinema. Some view literature, painting, sculpture, and music as the main four arts, of which the others are derivative; drama is literature with acting, dance is music expressed through motion, and song is music with literature and voice. Film is sometimes called the "eighth" and comics the "ninth art". Visual arts Architecture Architecture is the art and science of designing buildings and structures. The word architecture comes from the Greek arkhitekton, "master builder, director of works," from αρχι- (arkhi) "chief" + τεκτων (tekton) "builder, carpenter". A wider definition would include the design of the built environment, from the macrolevel of town planning, urban design, and landscape architecture to the microlevel of creating furniture. Architectural design usually must address both feasibility and cost for the builder, as well as function and aesthetics for the user. In modern usage, architecture is the art and discipline of creating, or inferring an implied or apparent plan of, a complex object or system. The term can be used to connote the implied architecture of abstract things such as music or mathematics, the apparent architecture of natural things, such as geological formations or the structure of biological cells, or explicitly planned architectures of human-made things such as software, computers, enterprises, and databases, in addition to buildings. In every usage, an architecture may be
