Vitruvius in the context of "Vitruvian Man"

Western culture, also known as Western civilization, European civilization, Occidental culture, Western society, or simply the West, is the internally diverse culture of the Western world. The term "Western" encompasses the social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies primarily rooted in European and Mediterranean histories. A broad concept, "Western culture" does not relate to a region with fixed members or geographical confines. It generally refers to the classical era cultures of Ancient Greece, Ancient Rome, and their Christian successors that expanded across the Mediterranean basin and Europe, and later circulated around the world predominantly through colonization and globalization.

Historically, scholars have closely associated the idea of Western culture with the classical era of Greco-Roman antiquity. However, scholars also acknowledge that other cultures, like Ancient Egypt, the Phoenician city-states, and several Near-Eastern cultures stimulated and influenced it. The Hellenistic period also promoted syncretism, blending Greek, Roman, and Jewish cultures. Major advances in literature, engineering, and science shaped the Hellenistic Jewish culture from which the earliest Christians and the Greek New Testament emerged. The eventual Christianization of Europe in late-antiquity would ensure that Christianity, particularly the Catholic Church, remained a dominant force in Western culture for many centuries to follow.

Architecture is the art and technique of designing and building, as distinguished from the skills associated with construction. It is both the process and the product of sketching, conceiving, planning, designing, and constructing buildings or other structures. The term comes from Latin architectura; from Ancient Greek ἀρχιτέκτων (arkhitéktōn) 'architect'; from ἀρχι- (arkhi-) 'chief' and τέκτων (téktōn) 'creator'. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.

The practice, which began in the prehistoric era, has been used as a way of expressing culture by civilizations on all seven continents. For this reason, architecture is considered to be a form of art. Texts on architecture have been written since ancient times. The earliest surviving text on architectural theories is the 1st century BC treatise De architectura by the Roman architect Vitruvius, according to whom a good building embodies firmitas, utilitas, and venustas (durability, utility, and beauty). Centuries later, Leon Battista Alberti developed his ideas further, seeing beauty as an objective quality of buildings to be found in their proportions. In the 19th century, Louis Sullivan declared that "form follows function". "Function" began to replace the classical "utility" and was understood to include not only practical but also aesthetic, psychological, and cultural dimensions. The idea of sustainable architecture was introduced in the late 20th century.

De architectura (On architecture, published as Ten Books on Architecture) is a treatise on architecture written by the Roman architect and military engineer Marcus Vitruvius Pollio and dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first known book on architectural theory, as well as a major source on the canon of classical architecture.

It contains a variety of information on Greek and Roman buildings, as well as prescriptions for the planning and design of military camps, cities, and structures both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). Since Vitruvius wrote early in the Roman architectural revolution that saw the full development of cross vaulting, domes, concrete, and other innovations associated with Imperial Roman architecture, his ten books give little information on these distinctive innovations of Roman building design and technology.

Ancient Greek technology developed during the 5th century BC, continuing up to and including the Roman period, and beyond. Inventions that are credited to the ancient Greeks include the gear, screw, rotary mills, bronze casting techniques, water clock, water organ, the torsion catapult, the use of steam to operate some experimental machines and toys, and a chart to find prime numbers. Many of these inventions occurred late in the Greek period, often inspired by the need to improve weapons and tactics in war. However, peaceful uses are shown by their early development of the watermill, a device which pointed to further exploitation on a large scale under the Romans. They developed surveying and mathematics to an advanced state, and many of their technical advances were published by philosophers, like Archimedes and Heron.

"In his explicit turn back to an ancient model in search of knowledge and wisdom, Leonardo follows early humanist practice. What he finds in Vitruvius is a mathematical formula for the proportions of all parts of the human body, which results in its idealized representation as the true microcosmic measure of all things. [...]The perfection of this ideal human form corresponds visually to the early humanist belief in the unique central placement of human beings within the divine universal order and their consequent human grandeur and dignity, expressed in the philosopher Pico della Mirandola's Oration on the Dignity of Man (1486), known as the manifesto of the Renaissance."

Renaissance humanism is a worldview centered on the nature and importance of humanity that emerged from the study of Classical antiquity.

Renaissance humanists sought to create a citizenry able to speak and write with eloquence and clarity, and thus capable of engaging in the civic life of their communities and persuading others to virtuous and prudent actions. Humanism, while set up by a small elite who had access to books and education, was intended as a cultural movement to influence all of society. It was a program to revive the cultural heritage, literary legacy, and moral philosophy of the Greco-Roman civilization.

Classical architecture typically refers to architecture consciously derived from the principles of Greek and Roman architecture of classical antiquity, or more specifically, from De architectura (c. 10 AD) by the Roman architect Vitruvius. Variations of classical architecture have arguably existed since the Carolingian Renaissance, and became especially prominent during the Italian Renaissance and the later period known as neoclassical architecture or Classical revival. While classical styles of architecture can vary, they generally share a common "vocabulary" of decorative and structural elements. Across much of the Western world, classical architectural styles have dominated the history of architecture from the Renaissance until World War II. Classical architecture continues to influence contemporary architects.

The term classical architecture can also refer to any architectural tradition that has evolved to a highly refined form, such as classical Chinese or Mayan architecture. It may also describe architecture that adheres to classical aesthetic philosophy. The term might be used differently from "traditional" or "vernacular architecture", it can share underlying axioms with it.

Cesare di Lorenzo Cesariano (December 10, 1475 – March 30, 1543) was an Italian painter, architect and architectural theorist. He authored the first Italian-language version of Vitruvius' De architectura.
