The Etruscans, probably influenced by a few rare Greek examples in southern Italy, developed the true arch in stone. A late specimen of the 3rd century bce is the Porta Marzia, an arched city gateway with a span of about 6 metres 20 feetin Perugia. The Etruscans also had a highly developed terra-cotta technology and made excellent fired bricks.

Masonry construction The Romans adopted Etruscan stone construction based on the arch and built many spectacular examples of what they called opus quadratum, or structures of cut stone blocks laid in regular courses. Oddly enough, such long spans in stone were never applied to buildings.

The surviving Roman buildings with stone arches or vaults have typical spans of only 4 to 7 metres 15 to 25 feet ; small stone domes with diameters of 4 to 9 metres were built in Roman Syria.

Such arches and domes imply the existence of sophisticated timber formwork to support them during construction, as well as advanced lifting machinerybut there are no extant records of either. Brickmaking, particularly in the region of Rome itself, became a major industry and finally, under the empire, a state monopoly.

Brick construction was cheaper than stone due to the economies of scale in mass production and the lower level of skill needed to put it in place.

The brick arch was adopted to span openings in walls, precluding the need for lintels. Mortar was at first the traditional mixture of sand, lime, and water, but, beginning in the 2nd century bce, a new ingredient was introduced.

The Romans called it pulvis puteoli after the town of Puteoli modern Pozzuolinear Naples, where it was first found; the material, formed in Mount Vesuvius and mined on its slopes, is now called pozzolana.

When mixed with lime, pozzolana forms a natural cement that is much stronger and more weather-resistant than lime mortar alone and that will harden even under water. Pozzolanic mortars were so strong and cheap, and could be placed by labourers of such low skill, that the Romans began to substitute them for bricks in the interiors of walls; the outer wythes of bricks were used mainly as forms to lay the pozzolana into place.

Finally, the mortar of lime, sand, water, and pozzolana was mixed with stones and broken brick to form a true concrete, called opus caementicium.

This concrete was still used with brick forms in walls, but soon it began to be placed into wooden forms, which were removed after the concrete had hardened. Early concrete structures One of the earliest surviving examples of this concrete construction is the Temple of the Sybil or Temple of Vesta at Tivoli, built during the 1st century bce.

This temple has a circular plan with a peristyle of stone columns and lintels around the outside, but the wall of the circular cella, or sanctuary room, inside is built of concrete—an uneasy confrontation of new and traditional forms of construction.

An early large-scale example in Rome itself of brick-faced concrete is the plain rectangular walls of the Camp of the Praetorian Guardbuilt by Sejanus in 21—23 ce. But the possibilities of plastic form suggested by this initially liquid material, which could easily assume curved shapes in plan and section, soon led to the creation of a series of remarkable interior spaces, spanned by domes or vaults and uncluttered by the columns required by trabeated stone construction, that showed the power of the imperial state.- Updated Daily - Print out daily news stories for friends, colleagues, students, family or co-workers!

It's moot where they came from, though they are generally believed to have settled in Italy from somewhere else. Or at least a small group did and perhaps converted many of the older inhabitants. The Etruscans and their influence on Rome.

In view of the utilization of the Etruscans’ art and engineering, the Romans had expanded more on a noteworthy scale than the Greeks, who utilized the post and lintel (a pillar bolstered by two sections).

Catholics try, rather unconvincingly, to show how conferring sainthood is different in principle to the pagan apotheosis (the process that made Claudius, for instance, into a God), but the distinction doesn't quite wash.
