Neoclassical Architecture, Enlightenment Ideology, and Classical Antiquity

Terminology, Historical Timelines, and Architectural Frameworks

• Definitions and Etymology:

  • Prefix "Neo": Means "new".

  • Classical: Pertains strictly to Classical Antiquity, specifically Ancient Greece and Ancient Rome.

  • Neoclassical: Denotes an architectural and intellectual movement emerging after antiquity during the eighteenth-century Age of Enlightenment.

  • Plasticism and Neoplasticism: Concepts framing architectural development as building upon preceding structural foundations to form new groupings, typologies, and expressions of buildings.

• Historical Timeline and Chronological Gap:

  • Classical Antiquity: The period encompassing classical Ancient Greece and Rome.

  • Chronological Gap: Approximately $2000$\,years separate classical antiquity from eighteenth-century neoclassicism.

  • Eighteenth Century Breakdown: Refers to the $1700\text{s}$, specifically the second half of the century from $1750\text{ CE}$ through the late $1700\text{s}$.

  • Sequence of Historical Eras:

  • Classical Antiquity $\rightarrow$ Middle Ages $\rightarrow$ Age of Enlightenment ($18\text{th}$ century).

  • Historical Context of the Enlightenment:

  • The Middle Ages were historically associated with castles and perceived intellectual darkness.

  • The Age of Enlightenment emerged as a reaction against the Middle Ages, seeking to shine light on the present ($18\text{th}$ century) by reaching back to the principles of classical antiquity.

• The Fundamental Paradox of Architectural Modernity:

  • Modernity assumes forward progress and the continuous improvement of current generations over past generations.

  • Eighteenth-century architects held the paradox that an architectural system from $2000$\,years prior represented the ultimate standard of perfection and advancement.

  • Rather than advancing strictly beyond the past, eighteenth-century architects defined modernity through a direct, re-evaluated relationship with antiquity.

Philosophical Foundations of the Classical Ideal and Political Implications

• Beyond Physical and Stylistic Attributes:

  • Common/Layperson Definition: Defines classical and neoclassical architecture solely by physical features, such as columns, pediments, domes, and symmetrical compositions.

  • Comprehensive Definition: Neoclassicism extends far beyond physical aesthetics; it represents a comprehensive system of thinking about history, knowledge, nature, society, politics, and the human body during the Enlightenment.

  • Subtitle Framework: The Classical Ideal and the Body Politic.

• The Classical Ideal:

  • Greek and Roman architects were believed to have discovered fundamental, universal truths regarding architectural design.

  • Fundamental Architectural Truths: Proportions, harmony, order, beauty, and the exact physical relationship between the human body and the built environment.

  • Universality: The classical ideal asserts that antiquity provides timeless principles of architectural excellence that serve as a measuring stick for modern achievements.

  • Role of the Modern Architect: Modern architects were not expected to mechanically copy ancient structures; instead, they were tasked with rationally recovering underlying ancient principles and applying them to modern societal needs using newly developed technologies.

• Political and Ethical Contradictions in Neoclassicism:

  • Central Paradox Question: Why did eighteenth-century Europeans and Americans look backward to ancient Greece and Rome to imagine a future for themselves in geographic locations outside of Greece and Rome?

  • Architectural Ethics and Unfree Labor:

  • Neoclassical architecture was explicitly adopted to represent ideals of liberty, freedom, and democracy.

  • Paradoxically, these spaces were frequently designed and constructed through systems of enslavement and unfree labor.

  • Key Exemplars (as analyzed by scholar Louis Nelson):

  • Monticello (estate of Thomas Jefferson).

  • The University of Virginia.

Epistemology and the Transmission of Classical Knowledge

• The Problem of Historical Distance and Evidence:

  • Eighteenth-century architects lacked modern analytical and recording tools (e.g., photography, satellite imagery, $3\text{D}$ digital modeling, modern archaeological science, and measured online databases).

  • Determining the exact physical reality and idealized forms of ancient buildings required alternative channels of transmission.

• Three Primary Sources of Classical Authority:

  • Written Texts: Theoretical treatises and commentaries preserved on paper.

  • Ruins / Site Investigation: Physical travel to ancient sites in Greece and Rome to excavate, observe, and directly measure surviving monuments.

  • Architectural Drawings: Non-written visual records documenting structural layouts, proportions, and details.

• Historiographical Approach (Bergdoll Framework):

  • Neoclassicism emerged alongside modern scientific inquiry, systematic archaeological taxonomy, historical investigation, and evolving concepts of human progress.

  • Shift in Architectural Knowledge: Transitioned from personal anecdotal observation ("I have seen this ancient building") to rigorous, scientific inquiry ("establishing precisely what the building was, how it was constructed, and what architectural principles it embodies").

Written Authorities and Theoretical Mediations

• Vitruvius (Marcus Vitruvius Pollio):

  • Historical Context: Roman architect and writer active during the first century BCE ($1\text{st}$ century BCE).

  • Treatise: Author of The Ten Books of Architecture (De architectura).

  • Historical Importance: Represents the only comprehensive architectural treatise to survive intact from classical antiquity.

  • Rediscovery: Rediscovered in the early $15\text{th}$ century, becoming the foundational text for Renaissance and Enlightenment architectural theory.

  • Theory vs. Practice Distinction: Vitruvius does not merely document practical Roman construction steps; he presents an interpretive theory of what architecture ought to be. Treatises are inherently interpretive rather than purely objective archaeological records.

• Leonardo da Vinci and the Vitruvian Man:

  • Creation: Renaissance diagram created by Leonardo da Vinci, directly inspired by Vitruvius's writings on human body proportions.

  • Visual Structure: Inscribes a male human body simultaneously within a square and a circle.

  • Philosophical Concept: Connects Vitruvian theory to the human body, positioning the body as the ultimate measuring instrument for spatial and architectural design.

  • Ideological Exclusions:

  • Promotes a rigid social and spatial order based on an assumed "ideal" body.

  • Explicitly excludes female bodies, non-standard physical proportions, and diverse human body types.

• Claude Perrault:

  • Context: Seventeenth-century French architect.

  • Contribution: Translated, illustrated, edited, and reinterpreted Vitruvius's Latin text into French (published in the $1600\text{s}$).

  • Impact: Enabled global distribution of classical architectural theory to non-Latin readers.

  • Mediated Knowledge: Demonstrates that eighteenth-century architects rarely encountered antiquity directly; their understanding was shaped by modern interpreters carrying their own historical and cultural biases.

Ancient Greek Architectural Case Study: The Parthenon

• Historical Details:

  • Location: The Acropolis in Athens, Greece.

  • Construction Dates: Built between $447\text{ BCE}$ and $432\text{ BCE}$ during the golden age of classical Athens.

  • Civic Role: Built when Athens was the political and cultural center of Greece; dedicated to Athena, the city's patron goddess.

  • Historical Age: Approximately $2000$\,years old by the eighteenth century.

• Chronological Transformation and Re-use:

  1. Classical Greek Temple (5th century BCE).

  2. Christian Church.

  3. Islamic Mosque (following the Ottoman conquest of Athens in $1458\text{ CE}$).

• Destruction into Ruin:

  • The structure remained substantially intact for over two millennia until the late $17\text{th}$ century.

  • Venetian Siege of Athens ($1687\text{ CE}$): The Ottoman army utilized the Parthenon as a gunpowder magazine. A Venetian projectile struck the building, triggering a massive explosion that brought down the roof, cella walls, and central structural framework.

  • Eighteenth-century architects encountered the building specifically as a ruin created by modern military conflict.

• Early Visual Record:

  • Cyriacus of Ancona Drawing: Created in the $15\text{th}$ century, predating the $1687\text{ CE}$ explosion.

  • Historical Role: Cyriacus was a humanist traveler documenting ancient monuments, representing the early pre-scientific stage of recording ruins prior to modern archaeological measurement.

Ancient Roman Architectural Case Study: The Pantheon

• Historical Details:

  • Location: Rome, Italy.

  • Construction Dates: Rebuilt in its existing form under Emperor Hadrian between $118\text{ CE}$ and $125\text{ CE}$.

  • Etymology: Derived from Greek, translating to "all the gods"; originally dedicated to the worship of multiple Roman deities.

• Structural and Engineering Innovations:

  • Features a massive unreinforced concrete dome measuring $43\,\text{m}$ ($43$\,meters) in diameter.

  • Technological Significance: Demonstrates advanced Roman concrete formulation and structural engineering.

  • Spatial Perception: The interior volume creates a feeling of dramatic verticality and expansiveness that appears much larger than its external elevation suggests.

• Continuous Operational Use:

  • Converted into a Christian church (Church of Santa Maria and the Martyrs).

  • Uninterrupted, continuous active use over two millennia prevented the building from being abandoned, dismantled, or turned into a ruined state, ensuring its survival in near-pristine condition.

• Enlightenment Rational Inquiry:

  • Studied during the Enlightenment not just as an aesthetic artifact, but as a technical subject for investigating concrete materials, structural load distributions, structural proportions, and geometric ratios.

Questions & Discussion

• Meaning of Neoplasticism and Neoclassicism:

  • Patrick noted that neoplasticism/neoclassicism involves building upon existing historical foundations to make something new, creating novel groupings of buildings.

  • Matthew highlighted that eighteenth-century thinkers examined ancient Rome and Greece to adopt their structural systems while adapting them to suit contemporary needs.

  • Clarification confirmed that classical architecture belongs strictly to Antiquity, whereas neoclassicism belongs to the post-Renaissance Age of Enlightenment.

• Onsite Observation of the Parthenon in Athens:

  • Visitors to the Acropolis noted the extreme ambient heat of the site.

  • Direct observation reveals a contrast between the broken, roofless state of the structure and the grounded sturdiness of its standing columns.

  • Sculptural elements remaining on the physical monument are modern replicas, as surviving original relief sculptures are preserved inside climate-controlled museum environments.

• Onsite Observation of the Pantheon in Rome:

  • Visitors noted that the interior space feels dramatically taller and larger than its exterior footprint implies.

  • Variable weather patterns directly affect the interior experience due to the open oculus, allowing sunlight and rain to enter the central hall.

• Exclusionary Aspects of the Vitruvian Man:

  • Discussion confirmed that designing architecture around human physical mobility accounts for dynamic spatial requirements and directional forces.

  • Critical observation noted that the Vitruvian diagram explicitly utilizes a male body, establishing a normative architectural benchmark that excludes female bodies and non-conforming physical shapes.
