1. ROMAN ARCHITECTURE

2. INTRODUCTION Roman Architecture Ancient Roman architecture developed different aspects of Ancient Greek architecture and newer technologies such as the arch and the dome to make a new architectural style. Roman architecture flourished throughout the Empire during the Pax Romana. Its use of new materials, particularly concrete, was a very important feature. 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.

3. Tuscan order Has been described as "the solidest and least ornate". Tuscan order was an older primitive Italic architectural form, predating the Greek Doric and lonic . In its simplicity, The Tuscan order is seen as similar to the Doric order, and yet in its overall proportions and intercolumniation, it follows the ratios of the lonic order.

4. Composite order The composite order is a mixed order, combining the volutes of the lonic order capital with the acanthus leaves of the Corinthian order. The composite order volutes are larger, however, and the composite order also has the moulding with egg-and-dart ornamentation between the volutes. The column of the composite order is 1:10 proportion. Until the Renaissance, the composite was not ranked as a separate order. Instead it was considered as a late Roman form of the Corinthian order.

5. PANTHEON The date in which the original Pantheon was constructed is unknown, but it was rebuilt in 126 AD. Roman temple built to honor all of the gods. Named for all of the statues placed around the building and its resemblance to the heavens. This circular building is constructed with a grand porch, three rows of columns, and a dome with a centered oculus to the sky. The Pantheons dome is still the largest unreinforced concrete dome in the world today.

Made out of travertine stone, mortar, bricks, and iron clamps. Contains arches, columns, arcades, and podiums. The Colosseum is one of the greatest feats of Roman architecture ever built. It is the largest Roman amphitheater in the world and despite suffering multiple  fires, earthquakes, and other natura l disasters  –as well as substantial mistreatment at the hands of men– it is still standing today
