The Art of Propaganda Roman Architecture
Roman art and architecture is greatly indebted to Greek models.
Roman art and architecture reflect the ambitions of a powerful empire Roman art and architecture reflect the ambitions of a powerful empire. Monumental buildings and sculptures were used as propaganda tools to glorify the empire and the emperor.
Concrete (lime, sand/ash, H20, stones) Concrete a Roman invention Part of why their architecture lasted so long Supposedly the best concrete made from volcano ash of a particular makeup found around Gulf of Naples (according to Pliny the Elder who died when Vesuvius erupted, covering Pompeii) For harbors, Romans mixed lime and volcanic ash to make a mortar, but wooden molds to form, and let it react with seawater to trigger a chem reaction and make it super strong
Before the arch… Earliest architecture system (Stonehenge). Works fine, but limited by how much weight it can support and how much room you can have between posts. Distributing the weight in a more complex way via arches allows for heavier ceilings and more space Arches replaced post and lintel in most buildings up until the Industrial Revolution and steel beams
Many on the ancient world used archs, but Romans were the first to use their full weight bearing potential.
Voussoirs: wedge-shaped units that form the arch Keystone: final wedge placed last, at the top of the arch. It balances the weight and force of the voissoirs and holds the arch together. Pier: The upright support that holds the weight of the arch
Arch of Constantine, Rome
Series of arches that counter one another’s thrust outward
You remember these… Corinthian was most popular in Roman architecture
Roman Arch Order All vaults are arches, but not all arches are vaults… Because a vault in a ceiling as well, and arches aren’t, always.
Series of arches placed one after another Were used in several ancient civilizations, but Romans and Persians only ones in ancient world to really use to full potential
Barrel vault in Spain
Intersection of two barrel vaults at right angles Intersection of two barrel vaults at right angles. Only needs to be supported at the four corners (economizing materials)
Dome!
Coffers and Oculus Coffer: Decorative sunken panals on a ceiling Oculus: “eye” – circular opening at center of dome; acts as “sun” for building (lights it)
Pendentives a curved triangle of vaulting formed by the intersection of a dome with its supporting arches
Basilica Public building for business or legal matters Interior space often divided by colonnades Basilica of Maxentius and Constantine
