Cement: c.200 BC |
Builders in Greek cities on the coast of Turkey (and in particular Pergamum) evolve cement in about 200 BC as a structural material, in place of weaker mortars such asgypsum plaster (used in Egypt) or bitumen (in Mesopotamia). The secret of the new material is the lime which binds sand, water and clay.
The Romans subsequently use finely ground volcanic lava inplace of clay, deriving it mainly from the region of Pozzuoli. Their cement, known for this reason as pozzolanic, is the strongest mortar in history until the development of Portland cement. When smallfragments of volcanic rubble are included, the result is concrete - making possible the great arches and aqueducts of Roman architecture, and playing its part in Roman roads. | |

|Vitruvius: late 1st century BC |
A Roman architect sets out the principles of his craft in ten volumes. He deals with all aspects, from general principles to materials, and from the Orders ofarchitecture to stucco work, painting, aqueducts and machinery. Written well before the greatest achievements of the Roman builders, this treatise is the most influential text in the entire history ofarchitecture.
The architect is Vitruvius and the book De architectura ('On architecture'). Its precepts subsequently guide the classical revival in the Renaissance. Since then the proportions andtheories of Greek and Roman architecture - as enshrined by Vitruvius - have remained the basis of architectural tradition. | |

Arch, vault and dome: from the 1st century BC |
Thegreatest achievement of Roman architecture and technology lies in the development of these three architectural forms. The dome has long been a familiar concept (appearing dramatically in the passage graveon the Île Longue or in the tholos at Mycenae), but nothing has been made of it in the major architectural traditions. The spectacular temples of Egypt or Greece are exclusively trabeate, using flat...
