Leon Battista Alberti in the context of "Architectural"

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.

Vitruvian Man (Italian: L'uomo vitruviano) is a drawing by the Italian Renaissance artist and scientist Leonardo da Vinci, dated to c. 1490. Inspired by the Roman architect Vitruvius, it depicts a nude man in two overlapping standing positions, inscribed within a circle and a square. Art historian Carmen C. Bambach described it as "justly ranked among the all-time iconic images of Western civilization". While not the only drawing inspired by Vitruvius, Leonardo's work uniquely combines artistic vision with scientific inquiry and is often considered an archetypal representation of the High Renaissance.

The drawing illustrates Leonardo's study of ideal human proportions, derived from Vitruvius but refined through his own observations, contemporary works, and the treatise De pictura by Leon Battista Alberti. Created in Milan, the Vitruvian Man likely passed to his student Francesco Melzi, and later to Venanzio de Pagave, who encouraged engraver Carlo Giuseppe Gerli to publish an engraving of it, spreading the image widely. It was then owned by Giuseppe Bossi, before being acquired in 1822 by the Gallerie dell'Accademia in Venice, where it remains. Because of its fragility, the drawing is rarely displayed. It was loaned to the Louvre in 2019 for the 500th anniversary of Leonardo's death.

Filippo di ser Brunellesco di Lippo Lapi (1377 – 15 April 1446), commonly known as Filippo Brunelleschi (/ˌbruːnəˈlɛski/ BROO-nə-LESK-ee; Italian: [fiˈlippo brunelˈleski]) and also nicknamed Pippo by Leon Battista Alberti, was an Italian architect, designer, goldsmith, and sculptor. He is considered to be a founding father of Renaissance architecture. He is recognized as the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, and for the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. Most surviving works can be found in Florence.

De pictura (English: "On Painting") is a treatise or commentarii written by the Italian humanist and artist Leon Battista Alberti. The first version, composed in Latin in 1435, was not published until 1450. It is one of his three treatises on art; the other two are De statua and De re aedificatoria, that would form the Renaissance concept for the fine arts: painting, sculpture, and architecture.

Johannes Trithemius (/trɪˈθɛmiəs/; 1 February 1462 – 13 December 1516), born Johann Heidenberg, was a German Benedictine abbot and a polymath who was active in the German Renaissance as a lexicographer, chronicler, cryptographer, and occultist. He is considered the founder of modern cryptography (a claim shared with Leon Battista Alberti) and steganography, as well as the founder of bibliography and literary studies as branches of knowledge. He had considerable influence on the development of early modern and modern occultism. His students included Heinrich Cornelius Agrippa and Paracelsus.

A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of parallel lines in three-dimensional space appear to converge. When the set of parallel lines is perpendicular to a picture plane, the construction is known as one-point perspective, and their vanishing point corresponds to the oculus, or "eye point", from which the image should be viewed for correct perspective geometry. Traditional linear drawings use objects with one to three sets of parallels, defining one to three vanishing points.

Italian humanist polymath and architect Leon Battista Alberti first introduced the concept in his treatise on perspective in art, De pictura, written in 1435. Straight railroad tracks are a familiar modern example.

De re aedificatoria (On the Art of Building) is a classic architectural treatise written by Leon Battista Alberti between 1443 and 1452. Although largely dependent on Vitruvius's De architectura, it was the first theoretical book on the subject written in the Italian Renaissance, and in 1485 it became the first printed book on architecture. It was followed in 1486 with the first printed edition of Vitruvius.

A villa is a type of house that was originally an ancient Roman upper class country house that provided an escape from urban life. Since its origins in the Roman villa, the idea and function of a villa have evolved considerably. After the fall of the Roman Republic, villas became small farming compounds, which were increasingly fortified in Late Antiquity, sometimes transferred to the Church for reuse as a monastery. They gradually re-evolved through the Middle Ages into elegant upper-class country homes. In the early modern period, any comfortable detached house with a garden near a city or town was likely to be described as a villa; most surviving villas have now been engulfed by suburbia. In modern parlance, "villa" can refer to various types and sizes of residences, ranging from the suburban semi-detached double villa to, in some countries, especially around the Mediterranean, residences of above average size in the countryside.
