Johann Joachim Winckelmann in the context of "Modern archaeology"

Neoclassicism, also spelled Neo-classicism, emerged as a Western cultural movement in the decorative and visual arts, literature, theatre, music, and architecture that drew inspiration from the art and culture of classical antiquity. Neoclassicism was born in Rome, largely due to the writings of Johann Joachim Winckelmann during the rediscovery of Pompeii and Herculaneum. Its popularity expanded throughout Europe as a generation of European art students finished their Grand Tour and returned from Italy to their home countries with newly rediscovered Greco-Roman ideals. The main Neoclassical movement emerged from the 18th-century Age of Enlightenment, and reached its peak in the early-to-mid-19th century, eventually competing with Romanticism. In architecture, the style endured throughout the 19th, 20th, and into the 21st century.

European Neoclassicism in the visual arts began c. 1760 in opposition to the then-dominant Rococo style. Rococo architecture emphasizes grace, ornamentation and asymmetry; Neoclassical architecture is based on the principles of simplicity and symmetry, which were seen as virtues of the arts of Ancient Rome and Ancient Greece, and drawn directly from 16th-century Renaissance Classicism. Each "neo"-classicism movement selects some models among the range of possible classics that are available to it, and ignores others. Between 1765 and 1830, Neoclassical proponents—writers, speakers, patrons, collectors, artists and sculptors—paid homage to an idea of the artistic generation associated with Phidias, but sculpture examples they actually embraced were more likely to be Roman copies of Hellenistic sculptures. They ignored both Archaic Greek art and the works of late antiquity. The discovery of ancient Palmyra's "Rococo" art through engravings in Robert Wood's The Ruins of Palmyra came as a revelation. With Greece largely unexplored and considered a dangerous territory of the Ottoman Empire, Neoclassicists' appreciation of Greek architecture was predominantly mediated through drawings and engravings which were subtly smoothed and regularized, "corrected" and "restored" monuments of Greece, not always consciously.

The Apollonian and the Dionysian are philosophical and literary concepts represented by a duality between the figures of Apollo and Dionysus from Greek mythology. Its popularization is widely attributed to the work The Birth of Tragedy by Friedrich Nietzsche, though the terms had already been in use prior to this, such as in the writings of poet Friedrich Hölderlin, historian Johann Joachim Winckelmann, and others. The word Dionysian occurs as early as 1608 in Edward Topsell's zoological treatise The History of Serpents. The concept has since been widely invoked and discussed within Western philosophy and literature.

In Greek mythology, Apollo and Dionysus are both sons of Zeus. Apollo, son of Leto, is the god of the sun, art, plague and disease, of rational thinking and order, and appeals to logic, prudence and purity and stands for reason. Dionysus, son of Semele, is the god of wine, dance and pleasure, of irrationality and chaos, representing passion, emotions and instincts. The ancient Greeks did not consider the two gods to be opposites or rivals, although they were often entwined by nature.

Neoclassical Hellenism is a term introduced primarily during the European Romantic era by Johann Joachim Winckelmann.

Alessandro Albani (15 October 1692 – 11 December 1779) was a Roman Catholic cardinal remembered as a leading collector of antiquities, dealer and art patron in Rome. He supported the art historian, Johann Joachim Winckelmann and commissioned paintings from Anton Raphael Mengs. As a cardinal (from 1721) he furthered the interests of the governments of Austria, Savoy and Britain against those of France and Spain; he was a noted jurist and papal administrator in his earlier career. Upon his death he was the last cardinal created by Pope Innocent XIII.
