context_page_description: Ancient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and even more so under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the empire, sometimes complete and still in use to this day.
  Roman architecture covers the period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture. Almost no substantial examples survive from before about 100 BC, and most of the major survivals are from the later empire, after about 100 AD.
context_section_description: Roman temples were among the most important and richest buildings in Roman culture, though only a few survive in any sort of complete state. Their construction and maintenance was a major part of ancient Roman religion, and all towns of any importance had at least one main temple, as well as smaller shrines. The main room (cella) housed the cult image of the deity to whom the temple was dedicated, and often a small altar for incense or libations. Behind the cella was a room or rooms used by temple attendants for storage of equipment and offerings.
  Some remains of many Roman temples survive, above all in Rome itself, but the relatively few near-complete examples were nearly all converted to Christian churches (and sometimes subsequently to mosques), usually a considerable time after the initial triumph of Christianity under Constantine. The decline of Roman religion was relatively slow, and the temples themselves were not appropriated by the government until a decree of the Emperor Honorius in 415. Some of the oldest surviving temples include the Temple of Hercules Victor (mid 2nd century BC) and Temple of Portunus (120–80 BC), both standing within the Forum Boarium.
  The form of the Roman temple was mainly derived from the Etruscan model, but using Greek styles. Roman temples emphasised the front of the building, which followed Greek temple models and typically consisted of wide steps leading to a portico with columns, a pronaos, and usually a triangular pediment above, which was filled with statuary in the most grand examples; this was as often in terracotta as stone, and no examples have survived except as fragments. However, unlike the Greek models, which generally gave equal treatment to all sides of the temple, which could be viewed and approached from all directions, the sides and rear of Roman temples might be largely undecorated (as in the Pantheon, Rome and Vic), inaccessible by steps (as in the Maison Carrée and Vic), and even back on to other buildings. As in the Maison Carrée, columns at the side might be half-columns, emerging from ("engaged with" in architectural terminology) the wall. The platform on which the temple sat was typically raised higher in Roman examples than Greek, with up ten or twelve or more steps rather than the three typical in Greek temples; the Temple of Claudius was raised twenty steps. These steps were normally only at the front, and typically not the whole width of that.
  The Greek classical orders in all their details were closely followed in the façades of temples, as in other prestigious buildings. However the idealized proportions between the different elements set out by the only significant Roman writer on architecture to survive, Vitruvius, and subsequent Italian Renaissance writers, do not reflect actual Roman practice, which could be very variable, though always aiming at balance and harmony. Following a Hellenistic trend, the Corinthian order and its variant the Composite order were most common in surviving Roman temples, but for small temples like that at Alcántara, a simple Tuscan order could be used.
  There was considerable local variation in style, as Roman architects often tried to incorporate elements the population expected in its sacred architecture. This was especially the case in Egypt and the Near East, where different traditions of large stone temples were already millennia old. The Romano-Celtic temple was a simple style for small temples found in the Western Empire, and by far the most common type in Roman Britain. It often lacked any of the distinctive classical features, and may have had considerable continuity with pre-Roman temples of the Celtic religion.
