what was concrete made out of in ancient rome
Roman concrete Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar â€“ a binder mixed with water that hardens over time. The aggregate varied, and included pieces of rock, ceramic tile, and brick rubble from the remains of previously demolished buildings.
Roman art While Greek sculptors traditionally illustrated military exploits through the use of mythological allegory, the Romans used a more documentary style. Roman reliefs of battle scenes, like those on the Column of Trajan, were created for the glorification of Roman might, but also provide first-hand representation of military costumes and military equipment. Trajan's column records the various Dacian wars conducted by Trajan in what is modern day Romania. It is the foremost example of Roman historical relief and one of the great artistic treasures of the ancient world. This unprecedented achievement, over 650 foot of spiraling length, presents not just realistically rendered individuals (over 2,500 of them), but landscapes, animals, ships, and other elements in a continuous visual history – in effect an ancient precursor of a documentary movie. It survived destruction when it was adapted as a base for Christian sculpture.[50] During the Christian era after 300 AD, the decoration of door panels and sarcophagi continued but full-sized sculpture died out and did not appear to be an important element in early churches.[10]
