Theories of Human & Urban Origins

Evolutionary / Orientalist (Lewis Mumford)

• Proposes progressive “biotechnic consciousness”:
  • Paleolithic: wandering bands, gradual domestication begins in Middle Europe & Middle East
  • Neolithic (~10{,}000 BCE): Agricultural Revolution ⇒ permanent villages ⇢ embryos of urbanism in SW & SE Asia
  • 4{,}000\text{ BCE}: Intensified settlement along big rivers gives first true cities
• Significance: frames city as a biological-cultural adaptation, not merely economic accident

Qurʼānic / Abrahamic View

• Founders: Adam A.S. & Ḥawwāʼ
• Human dispersal originates in “Arab lands” and radiates through Palestine, Jordan, Syria, Iraq/Iran, Egypt → global
• Ethical dimension: affirms single-origin brotherhood and stewardship responsibilities for land use

Opinions on How Cities Began

• Jane Jacobs: city grows directly from enlarged, increasingly complex agricultural villages
• Ceremonial nucleus hypothesis: first “germ” is a ritual/pilgrimage site drawing clans seasonally; over time fixes permanent habitation
  • Planning takeaway: symbolic functions precede commercial ones

Key Locational Determinants

• River basins (Nile, Tigris–Euphrates, Indus, Huang He)
  • Offer fertile alluvium, perennial water, transport corridors, mineable minerals → sustainable surplus
• Highlands / hills
  • Sacred perception; natural defence “bunkers”; climatic refuge

Early Settlement Morphology & Design Principles

• Planned towns with clear street layouts
  • Frequent use of geometric grids (square, rectangular, radial, round forms)
• Construction materials: brick & stone; infrastructure (walls, moats)
• Settlement form often encoded cosmology & social order
  • Scandinavia: solar & lunar worship → circular forms
  • China: “heaven = round, earth = square, king in centre” → cardinal city plans
  • India: cart-wheel mandala layouts (e.g. Vastu-Purusha diagrams)
  • Africa: concentric or hierarchical spatial segregation by class/strata

Functional Zoning (Slide 11 Schematic)

• Spanish-labelled monastic/latifundia layout – key spaces:
  • viviendas (dwellings)
  • granero (granary), corrales (corrals), establo/caballerizas (stables)
  • prensa de aceite (oil press), horno (oven), molino de grano (mill)
  • almacén (warehouse), herrería (smithy)
  • dormitorios de los esclavos (slave quarters), letrina (latrine)
• Illustrates early idea of separated functional precincts ⇒ precursor to modern zoning

Why River Valleys Favoured Civilisation

• Fertile soils from annual floods → high agricultural yield \Rightarrow surplus \Rightarrow labour specialisation
• Reliable water supply for drinking & irrigation
• Natural transport routes \leadsto trade networks, cultural diffusion
• Moat-like defence (rivers, marshes)
• Shared cosmological symbolism: life-giving water; many mythic creation stories begin with a river/ocean

General Characteristics of Civilisation (First-Wave, 3500\text{–}600\ BCE)

• Urbanism (dense, permanent settlements)
• Government (central authority, codified law)
• Organised religion (temples, priesthood)
• Job specialisation & social hierarchy
• Public works / monumental architecture (pyramids, ziggurats, city walls, granaries)
• Writing systems ➔ collective memory & administration

Four Old-World River-Valley Civilisations

Comparative Matrix

Mesopotamia (“Land Between Two Rivers”)

• Geography: alluvial plain between Taurus & Zagros; cities clustered from Sumer (south) to Assyria (north)

Sumer (3500–2006 BCE)

• Transition from open villages → walled city-states (e.g. Uruk, Ur, Lagash)
• Inventions: wheel, plough, bronze metallurgy, cuneiform tablets
• Political innovation: dynastic kingship (Sargon «the Great», founder of Akkadian Empire)

Babylon (1792–539 BCE)

• Synthesised Sumerian heritage; capital city becomes cultural–religious beacon
• Scientific legacies
  • 1\,\text{hour}=60\,\text{minutes}, 1\,\text{circle}=360^{\circ} sexagesimal math
  • Lunar calendar with 12 months
  • Multiplication & reciprocal tables (early mathematics education)
• Hammurabi’s Code: earliest comprehensive law ≈ 282 edicts carved in diorite

Assyria (1115–612 BCE)

• Militarised, expansionist; used chariots, iron weapons, siege engines
• Administered empire via provincial governors
• Urban achievements: ornate palaces (Nimrud, Nineveh), world’s first known library (Ashurbanipal)
• Engineered clay-pipe sewerage networks

Socio-cultural Frames

• Polytheism; four prime deities: An (heaven), Enlil (air), Enki (water), Ki (earth)
• Temple-economy: priests mediated between humans & gods; ziggurat as cosmic axis mundi
• Barter-based trade; canals & rivers as trade arteries

Ancient Egypt (ca. 3000 BCE)

• Nile’s predictable flood \Rightarrow “Black Land” (kemet) vs desert “Red Land” (deshret)
• Early unification under Menes/Narmer; capital at Memphis

Governance & Ideology

• Pharaoh: divine-king, apex of social pyramid; roles = {\text{hydraulic manager, war leader, law-giver, chief priest}}
• Succession through royal blood & chief wife; occasionally female pharaohs (e.g. Hatshepsut)

Notable Pharaohs & Contributions

• Menes: unifier; foundation myths
• Hatshepsut: obelisks, Deir el-Bahri terraced temple
• Akhenaten: Aten monotheism experiment; Amarna urban plan
• Tutankhamun: famous tomb; illustrates burial assemblage norms
• Ramses II: signed world’s first recorded peace treaty (with Hittites at Kadesh)

Accomplishments & Knowledge Systems

• Mathematics: geometric series, early algebra (Berlin Papyrus 6619 shows ax^2+bx=c forms)
• Engineering: pyramids (Old Kingdom), rock-cut temples (New Kingdom), canal works
• Writing: hieroglyphic, hieratic, later demotic scripts; scribal schools
• Religion: polytheistic pantheon (Ra, Osiris, Isis, Horus); afterlife-oriented funerary architecture

Indus Valley Civilisation (3300–1800 BCE)

• Core cities: Harappa, Mohenjo-Daro (gridded \approx!\,\text{N–S/E–W} streets, baked-brick houses)
• Zoning principles: acropolis (“citadel”) for ritual/admin; lower residential/commercial town; orthogonal alley hierarchy
• Infrastructure: covered drains, soak-pits, centralized granaries; earliest urban sanitation
• Evidence of standardised weights (\approx13.7\ g unit) ⇒ regulated trade
• Agriculture on double-silt Indus flood; crops: wheat, barley, cotton (earliest known cotton textiles), sesame, rice
• Political organisation inferred (no deciphered texts): likely priest-king governance; high survey/mathematical skills implied by precision plotting
• Crafts: high-fired pottery, faience beads, bronze figurines (“Dancing Girl”), imported metal → proof of long-distance trade (Mesopotamia “Meluhha” reference)

Ancient China along the Huang He (Yellow River)

• Neolithic precursors (Yangshao, Longshan) → early dynasties (Xia—semi-legendary; Shang \approx1600–1046\ BCE; Zhou \approx1046–256\ BCE)

Shang Highlights

• Capital at Yinxu (Anyang); royal palaces, ancestral temples, bronze foundries
• Oracle-bone script: earliest Chinese writing; divination + administration
• Social structure: king, nobility, bronze-smelting artisan class, peasants

Zhou Transformations

• Concept of “Mandate\ of\ Heaven” legitimises dynastic rule, sets cyclical theory of political planning (moral governance ⇔ cosmic order)
• Technological leaps
  • Iron metallurgy (~500\ BCE) ⇒ improved agricultural tools ⇒ higher surplus
  • Large-scale irrigation & canal works; road grids radiating from capital
  • Introduction of round copper coins \rightarrow monetised economy; fostered inter-regional trade along rivers and roads
• Silk production (sericulture) secret; by 1000\ BCE main export commodity → proto-Silk Road
• Writing unification across dialect zones enhanced administrative cohesion

Cross-Civilisational Connections to Modern Planning

• Grid-iron street pattern (Indus) re-emerges in Greek Hippodamian plans & modern U.S. towns
• Monumental axis (Egyptian processional ways, Mesopotamian ziggurat stairs) foreshadow Baroque boulevards and contemporary capital-city symbolism
• Hydraulic civilisations illustrate Karl Wittfogel’s “oriental despotism” hypothesis: water control necessitates centralised bureaucracy → parallels modern infrastructure governance
• Ethical takeaway: early cities tied ecological cycles (flood, silt) to governance; present planners must similarly integrate environmental processes

Numerical / Statistical References & Formulas

• Sexagesimal mathematics: 60\,\text{min}=1\,\text{hr}, 360^{\circ} circle, fractions expressed as 1/n “unit fractions” in Egypt
• Berlin Papyrus problem (simplified): ax^2 + bx = c solved via arithmetic series approximation
• Indus standard weight ≈ 13.7\ \text{g} → multiples/divisors found in trade cubical stones

Practical & Philosophical Implications for 21st-Century Planners

• Contiguity of water, food security, and urban form remains (climate-change flood management = modern Nile/Indus lessons)
• Ritual & identity spaces still anchor community cohesion (e.g. public squares, religious precincts)
• Governance legitimacy linked to infrastructure provision (Mandate of Heaven vs. present “social licence”)
• Sustainability insights: baked-brick + natural ventilation (Indus), solar orientation (Egypt) inspire green-building strategies
