The hemispherical building structure that evolved out of an arch is called a Dome.Domes form the roof of a building, with a strong base. They are strong and solid despite their slenderness.Many important modern and early historical buildings are covered by domes. This curved structure does not have any angles or corners but has a huge amount of space inside it. This attracted the Ancient Romans to this as it can be made without even one column. The Ancient Romans had built buildings with these domes which are still in existence.Ancient Rome is famous for its worldwide known domes which allowed the Ancient Romans to construct vaulted ceilings and large spaced rooms for the buildings throughout the Roman Empire. These Ancient Romans architectural domes were mostly seen in churches, temples and basilicas.The earlier method of constructing lintels and traditional posts was replaced by the Ancient Roman domes during the first century B.C. The earlier method used columns and even an architrave which was the idea of ancient Greeks.The constitution of domes was not typical like that of the traditional building of those times. Domes were made with concrete. This concrete is known as the opus caementicium. This Roman concrete had made a revolution in the field of architecture.The Ancient domes were not invented by Romans. It was patented by a mathematician of America named Buckminster Fuller. The Ancient Romans had just refined the methods. Ancient Romans thought the dome was the best way to make a large space without using many columns and the space’s roof was needed to support the walls.The extraordinarily constructed domes at the pantheon (pantheon domes) and at Baths of Diocletian are very famous.Christian places of worship have adopted the Ancient Roman domes, throughout the period of the Roman Empire. The half domes used by the empire were known as the apse which had then become a part of traditional church architecture.The real idea of domes came from the Middle East, Mediterranean and India. The idea was domes were first started with huts and small construction works. The huge number of domes made by Ancient Romans were shaped using concrete.The Evolution Of The Dome In The Roman EmpireThe Ancient Romans changed the history of architecture by introducing domes. They introduced the hemispherical structure called domes in Rome to know the potential of it to create large spaces and better interior spaces. The dome was established in Roman buildings such as thermae, temple, church and mausolea. The semi-domes also became popular in this period of the Roman Empire. Monumental Domes were seen in Rome around the first century BC.In the Ancient period, domes were to appear as small rounded huts, solid mounds and tombs. The idea of domes was not of Romans but of the Middle East, Mediterranean and India. Romans had introduced this hemispherical structure within the buildings of Rome.Romans realized the large space that can be created by limiting the many columns or walls that were to be needed to support the roof of the space. Domes evolved from the arch buildings, and domes then became a defining factor of Roman Architecture.Thus the domes exerted large force around their buildings. So that the traditional monuments with domes need to have big supporting walls to balance with the stress.The large dome’s construction was concealed partially or completely from the outer area of the building. In some cases, the masonry domes are concealed with conical and polygonal roofs.The fall of the Roman Empire is also the decline of the Roman Emperor. The fall of the Roman Empire led to the emergence of the Byzantine Empire to power. They developed the technology of domes even further. They raised domes on piers and made it so impressed with their continued efforts. Thus domes that were built on cubical bases started to be supported by pendentives.A pendentive is the inverted triangular work of masonry which shows the roots of a Byzantine-style dome. This horizontally and vertically curved structure filled the upper corner of the rooms.The rise of Gothic forms of architecture led to the fall of fashion of ancient domes but the Renaissance and Baroque periods can make it popular again.Interesting And Great Domes Of The Byzantine And Roman EmpirePantheon Dome, Red Basilica’s Rotundas, temple of mercury, Stabian Baths Frigidarium, Hagia Sophia’s Dome, Baptistery of Santa Maria Maggiore, Temple of Romulus are some of the major Domes of Rome and the Byzantines.The Pantheon is a building in Rome that has stood the test of time. It was once destroyed by fire and was rebuilt by Emperor Hadrian. The Pantheon is well known for its dome and is real evidence of the skills and genius minds of architects and engineers of Rome. Pantheon Dome is famous for its central eye (Oculus) which is diametrically 30 ft (9.1 m). The drains can filter away the water on rainy days. The Pantheon’s dome remained the largest dome in the world for about 1300 years.Red Basilica is a temple made by the Romans in an ancient city in Turkey and it is believed that the temple was dedicated to Egyptian gods, it was erected under the ruling period of Emperor Hadrian.The two attractive Rotundas with domes on each side of the temple is its main striking element. This rotunda has relieving arches but is not solid. The dome design is popular. This temple was later converted into a church by Emperor Hadrian.Santa Costanza is a church built by Constantine as a mausoleum or tomb for his dead daughter Constantina. The main feature of this church is its attractive central dome which has also a big ambulatory around the dome. The dome is shallow. This building is perfect evidence for the excellence of art or architecture of the early Christian.The Roman Empire was a great and influential civilization that lasted for around 1000 years. The empire which centered in Rome was established in 27 BCE. The first century BCE marked the endless civil wars which transformed Republican Rome to Imperial Rome.After Julis Caesar was assassinated, emperor Augustus was thrown into power. His period of ruling spread the empire with peace and stability. The government established by Augustus was known as the principate but the Senate was still functioning. August then tried to select the next emperor, his successor. Augustus had no male heir and Marcellus (nephew), Agrippa (son in law), Gaius and Lucius ( his grandsons) predeceased him.But Augustus adopted Tiberius, one in Claudia gens and made him the emperor. He was a brutal tyrant. Tiberius’s great-nephew, Caligula’s ruling period was filled with absolutism, murders, reckless spending and humiliated the senate. He drained the wealth of the empire.Vesasian then was crowned after the succession of endless war. He reorganized the army to make it more professional and loyal. But after his son, Titus’s, reign was marked with the bringing back of autocratic rule by Domitian (another son of Vesasian). He fought with the Senate class and confiscated games, costly buildings and shows. Domitian then was assassinated.The fall of the Roman Empire is marked by the establishment of barbarians like the Gothic tribe to power. The last Roman Emperor Romulus was overthrown by a leader of Germany called the Odoacer. He was the first barbarian king to rule Rome.Games In The ColosseumThe Roman Colosseum was designed for about 75000 people to sit. It was a marvel of engineering skills. The Colosseum was an imperial effort so as to revitalize the great Rome after the loud year of kingship by the four emperors.Emperor Vespasian considered the Colosseum as an entertainment venue to host animal hunts, gladiator fights and many other games. Gladiator games were the popular games in the Colosseum. Romans admired the gladiators who were the trained men to fight using weaponsThe animal hunt of the gladiators involved animals such as tigers, rhinos, giraffes, elephants, and bears. In most cases, the hungry animals would fight against the other animals who are hungry. At times the hungry animals would also fight against gladiators and this is called the venationes.All it would start with men parading. It would then be followed by religious ceremonies, animal hunting, horse racing, gladiator fights and executions.Practicality Of The DomeRomans built the domes with the fact they recognized the advantage of getting large space without the use of columns, walls or other supporting structures of the roof.Their mission was not possible with their technology in masonry, unreinforced concrete, columns and flat roofs as the masonic roof and reinforced concrete cannot span very long distances without failure and cracking. Concrete and masonry works better in compression but not well in tension.The form will bend, in using flatforms for spanning large distances. This bending would create compression stress and tensile stress on the top and bottom of the forms. This stress due to bending can create cracks on the side of tension. There is also a chance of collapsing the concrete or masonry if the cracking leads to the cross-section.The Romans might have tried such designs, they might have realized that they have to make a better method for obtaining large space in rooms. The intelligent Roman minds then chose the domes, as they can create a three-dimensional hemispherical form.The Roman engineers who realized the ability of masonry and concrete in spanning long distances with compression stress made it easier by developing a dome that is effective for creating large spans while using a three-dimensional effect.Roman Dome Influence And ImpactA curved structure generally made of brick, concrete, stone or steel is called an arch. An arch can strengthen or support a building. The Roman domes solved the inability of arches to not be able to give support to large weights. Do you then know about the influence and impact of the domes of Rome?The ancient architectural form of domes had a great influence on the contemporary and on the later styles. Roman domes had created an influence on Russian architecture and Ottoman architecture.Roman domes were adopted by several cultures. The Byzantine architects of East Europe and Romanesque architects of West Europe tried the domes in their architecture constantly. Many others also adopted the idea of domes and developed it. The Muslim architects of the Arab world created scalloped, pointed and horseshoe domes. They have used this in palaces and mosques. This borrowing and development of Roman domes meant that the domes would create a lasting impact on architecture.The Romans had also made further developments in the field of architecture. The arches were combined to make roofs and ceilings called the vaults. The Pantheon in Rome is the perfect example of the intelligent engineering minds of Rome.The many buildings you would visit in your daily life would be made with domes and vaults. Chartes, a Gothic cathedral in France, and the Taj Mahal in India would not have been possible without the idea of domes and arches.The dome made by Romans could support a large weight which made it possible for the Romans to make big buildings. The Roman dome then had created a lasting impact in the field of architecture all through the world.
The hemispherical building structure that evolved out of an arch is called a Dome.
