🏛️Art and Monuments of Augustan Rome Unit 8 – Materials and Construction in Augustan Rome

Key Materials Used

• Marble quarried from various locations across the Roman Empire (Carrara, Paros, Proconnesus)

• Travertine limestone mined near Tivoli
  • Utilized in the construction of the Colosseum and other major public buildings
  • Valued for its strength and resistance to weathering
• Tufa, a volcanic stone, used as a primary building material
  • Easily cut and shaped, making it suitable for quick construction
  • Often used in the core of walls and then faced with brick or marble
• Concrete, a revolutionary building material invented by the Romans
  • Consisted of a mixture of lime mortar, volcanic ash (pozzolana), water, and aggregate (small stones or brick fragments)
  • Allowed for the creation of vaults, domes, and other complex architectural forms
• Brick and terracotta tiles used extensively in construction
  • Mass-produced in standard sizes and shapes
  • Used for facing walls, creating decorative patterns, and roofing
• Wood employed for roofing, doors, and temporary scaffolding during construction

  • Employed in the construction of temples, public buildings, and city walls
• Opus caementicium, the use of Roman concrete
  • Revolutionized construction by allowing for greater flexibility in design and faster building times
  • Enabled the creation of vaults, domes, and other complex forms
• Arches and vaults used to span large spaces and support heavy loads
