Europe kept rediscovering Greece and Rome, and each revival meant something different
Classicism is the habit of treating ancient Greek and Roman culture as the yardstick of good taste: proportion, clarity, simplicity and emotion held in check. It surfaced under Charlemagne's heirs, flooded back in the Renaissance, propped up Louis XIV's absolutism and returned again in Enlightenment Neoclassicism.
At its core the idea is aesthetic. A classicist admires order, balance, structural clarity and feeling kept on a short leash, and addresses the mind rather than the nerves. Kenneth Clark, writing about the ancient discus thrower in The Nude (1956), argued that complaining about the statue's compression is really complaining about classical art itself, since any sudden burst of movement would have wrecked its poise. He also saw classicism as a canon: a set of ideal forms that many generations agreed to accept.
The tendency never stayed buried for long. It recurs in Late Antiquity and revives in Carolingian and Ottonian art, but the lasting return came in Renaissance Italy, when the collapse of Byzantium and growing commerce with Islamic societies poured ancient learning into Europe. Before then people had imagined an unbroken Christian story running back to Constantine. The Renaissance version brought mathematics and observation into painting, along with humanism, realism, pagan gods and a conscious pairing of old and new. Builders revived the classical column orders and used the golden rectangle for proportion, while sculptors took up bronze casting again.
By the sixteenth and seventeenth centuries the word had hardened into something more rigid: grids, geometry, discipline, formal academies of art and music. Louis XIV's court became its capital, borrowing the Olympian gods to dignify absolute monarchy. The same urge to recover Greek theatre helped produce modern opera, and Tudor playwrights sorted their work into tragedy and comedy on ancient lines. Learning ancient Greek became a mark of a proper liberal education.
The Enlightenment reinvented it once more, energised by Newton's physics, better instruments and admiration for Greek resistance to Persia. Baroque ornament gave way to self-declared neoclassical styles; Jacques-Louis David's paintings were read as a return to balance and vigour. In the nineteenth century classicism fed academic rules, and even rebels such as the Pre-Raphaelites cast themselves as classical correctives to emotional excess.
