Circus Maximus in the context of Porta Capena

The Hippodrome of Constantinople (Greek: Ἱππόδρομος τῆς Κωνσταντινουπόλεως, romanized: Hippódromos tēs Kōnstantinoupóleōs; Latin: Circus Maximus Constantinopolitanus; Turkish: Hipodrom) was a circus that was the sporting and social centre of Constantinople, capital of the Byzantine Empire. Today it is a square in Istanbul, Turkey, known as Sultanahmet Square (Turkish: Sultanahmet Meydanı).

The word hippodrome comes from the Greek hippos (ἵππος), horse, and dromos (δρόμος), path or way. For this reason, it is sometimes also called Atmeydanı ("Horse Square") in Turkish. Horse racing and chariot racing were popular pastimes in the ancient world and hippodromes were common features of Greek cities in the Hellenistic, Roman, and Byzantine eras.

The Temple of Cybele or Temple of Magna Mater was Rome's first and most important temple to the Magna Mater ("Great Mother"), who was known to the Greeks as Cybele. It was built to house a particular image or form of the goddess, a meteoric stone brought from Greek Asia Minor to Rome in 204 BC at the behest of an oracle and temporarily housed in the goddess of Victory's Palatine temple. The new temple was dedicated on 11 April 191 BC, and Magna Mater's first Megalesia festival was held on the temple's proscenium.

The temple was sited on the high western slope of the Palatine, overlooking the valley of the Circus Maximus and facing the temple of Ceres on the slopes of the Aventine. It was accessible via a long upward flight of steps from the flattened area or proscenium below, where the goddess's festival games and plays were staged. The goddess's altar was visible both from the proscenium and the temple's interior. The original temple burned down in 111 BC, and was restored by one Metellus, possibly Gaius Caecilius Metellus Caprarius. It burned on a further two occasions in the early Imperial era, and was restored each time by Augustus; his second rebuilding was probably the more sumptuous of the two.

Chariot racing (Ancient Greek: ἁρματοδρομία, harmatodromía; Latin: ludi circenses) was one of the most popular ancient Greek, Roman, and Byzantine sports. In Greece, chariot racing played an essential role in aristocratic funeral games from a very early time. With the institution of formal races and permanent racetracks, chariot racing was adopted by many Greek states and their religious festivals. Horses and chariots were very costly. Their ownership was a preserve of the wealthiest aristocrats, whose reputations and status benefitted from offering such extravagant, exciting displays. Their successes could be further broadcast and celebrated through commissioned odes and other poetry.

In standard Greek racing practise, each chariot held a single driver and was pulled by four horses, or sometimes two. Drivers and horses risked serious injury or death through collisions and crashes; this added to the excitement and interest for spectators. Most charioteers were slaves or contracted professionals. While records almost invariably credit victorious owners and their horses for winning, their drivers are often not mentioned at all. In the ancient Olympic Games, and other Panhellenic Games, chariot racing was one of the most important equestrian events, and could be watched by unmarried women. Married women were banned from watching any Olympic events but a Spartan noblewoman is known to have trained horse-teams for the Olympics and won two races, one of them as driver.

A Roman circus (from the Latin word that means "circle") was a large open-air venue used mainly for chariot races, although sometimes serving other purposes. It was similar to the ancient Greek hippodrome. Along with theatres and amphitheatres, circuses were one of the main entertainment venues at the time.

Similar buildings, called stadia were used for Greek-style athletics particularly in the eastern, Greek speaking, part of the empire, but these were typically smaller than circuses.

The Lateran Obelisk (Italian: Obelisco Lateranense; Latin: Obeliscus Constantii) is the largest standing ancient Egyptian obelisk in the world, and it is also the tallest obelisk in Italy. It originally weighed 413 tonnes (455 short tons), but after collapsing and being re-erected 4 metres (13 ft) shorter, now weighs around 300 tonnes (330 short tons). It is located in Rome, in the square across from the Archbasilica of Saint John Lateran and the San Giovanni Addolorata Hospital.

The obelisk was made around 1400 BC in Karnak, Egypt, during the reigns of Pharaohs Thutmose III and Thutmose IV. Roman Emperor Constantine I had it moved to Alexandria in the early 4th century AD, then Constantius II in AD 357 had it shipped to Rome and erected at the Circus Maximus. The obelisk collapsed and broke into pieces sometime after the Circus's abandonment in the 5th century and became buried. It was excavated and restored by Domenico Fontana in the late 1580s, and by the order of Pope Sixtus V was topped with a Christian cross and installed in its present location near the Lateran Palace.

The Great Fire of Rome (Latin: incendium magnum Romae) began on 19 July 64 AD. The fire started in the merchant shops around Rome's chariot stadium, Circus Maximus. After six days, the fire was brought under control, but before the damage could be assessed, the fire reignited and burned for another three days. In the aftermath of the fire, nearly three quarters of Rome had been destroyed (10 out of 14 districts).

According to Tacitus and later Christian tradition, Emperor Nero blamed the devastation on the Christian community in the city, initiating the empire's first persecution against the Christians. Other contemporary historians blamed Nero's incompetence but it is commonly agreed by historians nowadays that Rome was too densely populated and inadequately prepared to effectively deal with large scale disasters, including fires, and that such an event was inevitable.

Revivals of ancient Roman polytheism have taken various forms in the modern era. These efforts seek to re-establish the traditional Roman cults and customs, often referred to as cultus deorum romanorum (worship of the Roman gods), religio romana (Roman religion), via romana agli dei (the Roman way to the gods), Roman-Italic religion, or gentile Roman religion. Several loosely affiliated organizations have emerged in the contemporary period.

In ancient Roman religion, the Cerealia /sɪəriːˈeɪliə/ was the major festival celebrated for the grain goddess Ceres. It was held for seven days from mid- to late April. Various agricultural festivals were held in the "last half of April". The Cerealia celebrated the harvest, and may have begun on the 19th. Surviving descriptions of Rome's city festival of Ceres are presumably urban versions of an originally rustic, agricultural festival. In his treatise on agriculture, Cato the Elder recommends that farmers sacrifice a sow (porca praecidanea) to Ceres, before the harvest.

The Cerealia is listed on the oldest Roman calendars, and its institution in the city is attributed to the semi-legendary King Numa, in the earliest Regal period. The festival's archaic, agricultural nature is shown by a nighttime ritual described by Ovid. Blazing torches were tied to the tails of live foxes, who were released, possibly into the Circus Maximus. The origin and purpose of this ritual is unknown; it may have been intended to cleanse the growing crops and protect them from disease and vermin, or to add warmth and vitality to their growth. Ovid offers an aetiological explanation: long ago, at ancient Carleoli, a farm-boy caught a fox stealing chickens and tried to burn it alive. The fox escaped, ablaze; in its flight it set fire to the fields and their crops. As these were both sacred to Ceres, foxes are punished at her festival ever since.

The Velabrum (Classical Latin: [weː.laː.brũ]) is the low valley in the city of Rome that connects the Forum with the Forum Boarium, and the Capitoline Hill with the western slope of the Palatine Hill. The outer boundaries of the area are not themselves clear. Roman etymologies of the name are confused, with attempts to connect it to the Latin words vehere (conveyance) and velum (cloth): Varro, Propertius, and Tibullus claimed that it was the location of a ferry; Plutarch, however, claimed the name derived from the awnings placed over the Circus Maximus during games. The name may also translate to "place of mud".

It was believed that before the construction of the Cloaca Maxima, which probably follows the course of an ancient stream called Spinon, the area was a swamp, though this claim has been disproven by core samples taken from Velabrum in 1994. Varro claims there are two velabra, one maius and one minus, with the smaller emerging from the drainage of a swamp close to the northern side of the Forum: if there was any drainage the distinction between the two was largely forgotten by the last century BC when it was referred to in the plural for both. Ancient authorities state that in this marshy area, the roots of a fig tree (Ficus Ruminalis) caught and stopped the basket carrying Romulus and Remus as it floated along on the Tiber current. The place therefore has a high symbolic significance.

In ancient Roman religion, the god Consus was the protector of grains. He was represented by a grain seed. His altar (ara) was located at the first meta of the Circus Maximus. It was either underground, or according to other sources, covered with earth, which was swept off during the two Consualia, his festivals on August 21, December 15, and on July 7 when the pontiffs held a sacrifice there. He was thus a chthonic god.

The Flamen Quirinalis and the Vestals officiated at his rites.
