Roman currency in the context of Denarius

The Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis, was a period in Roman history during which the Roman Empire nearly collapsed under the combined pressure of repeated foreign invasions, civil wars and economic disintegration. At the height of the crisis, the Roman state split into three distinct and competing polities. The period is usually dated between the death of Severus Alexander (235) and accession of Diocletian (284).

The crisis began in 235 with the assassination of Emperor Severus Alexander by his own troops. During the following years, the empire saw barbarian invasions and migrations into Roman territory, civil wars, peasant rebellions and political instability, with multiple usurpers competing for power. This led to the debasement of currency and a breakdown in both trade networks and economic productivity, with the Plague of Cyprian contributing to the disorder. Roman armies became more reliant over time on the growing influence of the barbarian mercenaries known as foederati. Roman commanders in the field, although nominally loyal to the state, became increasingly independent of Rome's central authority.

Domitian (/dəˈmɪʃən, -iən/ də-MISH-ən, -⁠ee-ən; Latin: Domitianus; 24 October 51 – 18 September 96) was Roman emperor from 81 to 96. The son of Vespasian and the younger brother of Titus, his two predecessors on the throne, he was the last member of the Flavian dynasty. Described as "a ruthless but efficient autocrat", his authoritarian style of ruling put him at sharp odds with the Senate, whose powers he drastically curtailed.

Domitian had a minor and largely ceremonial role during the reigns of his father and brother. After the death of his brother, Domitian was declared emperor by the Praetorian Guard. His 15-year reign was the longest since Tiberius. As emperor, Domitian strengthened the economy by revaluing the Roman coinage, expanded the border defenses of the empire, and initiated a massive building program to restore the damaged city of Rome. Significant wars were fought in Britain, where his general Agricola made significant gains in his attempt to conquer Caledonia (Scotland), and in Dacia (Modern-day Romania), where Domitian was unable to achieve a decisive victory against King Decebalus. Domitian's government exhibited strong authoritarian characteristics. Religious, military, and cultural propaganda fostered a cult of personality, and by nominating himself as perpetual censor, he sought to control public and private morals.

The concept of liberty has frequently been represented by personifications, often loosely shown as a female classical goddess. Examples include Marianne, the national personification of the French Republic and its values of Liberté, Égalité, Fraternité, and the female Liberty portrayed in artworks, on United States coins beginning in 1793, and many other depictions. These descend from images on ancient Roman coins of the Roman goddess Libertas and from various developments from the Renaissance onwards. The Dutch Maiden was among the first, re-introducing the cap of liberty on a liberty pole featured in many types of image, though not using the Phrygian cap style that became conventional. The 1886 Statue of Liberty (Liberty Enlightening the World) by Frédéric Auguste Bartholdi is a well-known example in art, a gift from France to the United States.

Aurelian (/ɔːˈriːliən/; Latin: Lucius Domitius Aurelianus; 9 September c. 214 – c. November 275) was a Roman emperor who reigned from 270 to 275 during the Crisis of the Third Century. As emperor, he won an unprecedented series of military victories which reunited the Roman Empire after it had nearly disintegrated under the pressure of barbarian invasions and internal revolts. For his success in restoring the Empire's territorial integrity, Aurelian was honored with the title Restitutor Orbis ("Restorer of the World"). Born in modest circumstances, most likely in Moesia Superior, he entered the Roman army in 235 and climbed up the ranks. He went on to lead the cavalry of the emperor Gallienus, until Gallienus' assassination in 268. Following that, Claudius Gothicus became emperor until his own death in 270. Claudius' brother Quintillus then ruled for three months, before Aurelian took the empire for himself. Aurelian was chosen Roman emperor by the Illyriciani as one of themselves.During his reign, he defeated the Alamanni after a devastating war. He also defeated the Goths, Vandals, Juthungi, Sarmatians, and Carpi. Aurelian restored the Empire's eastern provinces after his conquest of the Palmyrene Empire in 273. The following year he conquered the Gallic Empire in the west, reuniting the Empire in its entirety. He was also responsible for the construction of the Aurelian Walls in Rome, the abandonment of the province of Dacia, and monetary reforms attempting to curb the devaluation of the Roman currency.Although Domitian, two centuries earlier, was the first emperor who had demanded to be officially hailed as dominus et deus ('master and god'), these titles never occurred in written form on official documents until the reign of Aurelian. His successes were instrumental in ending the crisis.

Medicine in ancient Rome was highly influenced by ancient Greek medicine, but also developed new practices through knowledge of the Hippocratic Corpus combined with use of the treatment of diet, regimen, along with surgical procedures. This was most notably seen through the works of two of the prominent Greek physicians, Dioscorides and Galen, who practiced medicine and recorded their discoveries. This is contrary to two other physicians like Soranus of Ephesus and Asclepiades of Bithynia, who practiced medicine both in outside territories and in ancient Roman territory, subsequently. Dioscorides was a Roman army physician, Soranus was a representative for the Methodic school of medicine, Galen performed public demonstrations, and Asclepiades was a leading Roman physician. These four physicians all had knowledge of medicine, ailments, and treatments that were healing, long lasting and influential to human history. Medicine in Ancient Rome was one of the most important influences to the modern medicine we have now.

Ancient Roman medicine was divided into specializations such as ophthalmology and urology. To increase their knowledge of the human body, physicians used a variety of surgical procedures for dissection that were carried out using many different instruments including forceps, scalpels and catheters.

The sestertius (pl.: sestertii) or sesterce (pl.: sesterces) was an ancient Roman coin. During the Roman Republic it was a small silver coin issued only on rare occasions. During the Roman Empire it was a large brass coin.

The name sestertius means "two and one half". It refers to the nominal value of two and a half asses, a value useful in commerce because it was one quarter of a denarius, a coin worth ten asses. The etymology is ancient. Latin writers derive sestertius from semis "half" and tertius "third", where "third" points to the third as, since two asses and half of a third equal two and a half.

SPQR or S.P.Q.R., an initialism for Senatus Populusque Romanus (Classical Latin: [sɛˈnaːtʊs pɔpʊˈɫʊskʷɛ roːˈmaːnʊs]; transl. "The Senate and People of Rome"), is an emblematic phrase referring to the government of the Roman Republic. It appears on documents made public by an inscription in stone or metal, in dedications of monuments and public works, and on some Roman currency.

The full phrase appears in Roman political, legal and historical literature, such as the speeches of Cicero and the Ab Urbe Condita Libri (Books from the Founding of the City) of Livy.

Between the Roman Empire and the Han dynasty, as well as between the later Eastern Roman Empire and various successive Chinese dynasties, there were (primarily indirect) contacts and flows of trade goods, information, and occasional travelers. These empires inched progressively closer to each other in the course of the Roman expansion into ancient Western Asia and of the simultaneous Han military incursions into Central Asia. Mutual awareness remained low, and firm knowledge about each other was limited. Surviving records document only a few attempts at direct contact. Intermediate empires such as the Parthians and Kushans, seeking to maintain control over the lucrative silk trade, inhibited direct contact between the two ancient Eurasian powers. In 97 AD, the Chinese general Ban Chao tried to send his envoy Gan Ying to Rome, but Parthians dissuaded Gan from venturing beyond the Persian Gulf. Ancient Chinese historians recorded several alleged Roman emissaries to China. The first one on record, supposedly either from the Roman emperor Antoninus Pius or from his adopted son Marcus Aurelius, arrived in 166 AD. Others are recorded as arriving in 226 and 284 AD, followed by a long hiatus until the first recorded Byzantine embassy in 643 AD.

The indirect exchange of goods on land along the Silk Road and sea routes involved (for example) Chinese silk, Roman glassware and high-quality cloth. Roman coins minted from the 1st century AD onwards have been found in China, as well as a coin of Maximian (Roman emperor from 286 to 305 AD) and medallions from the reigns of Antoninus Pius (r. 138–161 AD) and Marcus Aurelius (r. 161–180 AD) in Jiaozhi (in present-day Vietnam), the same region at which Chinese sources claim the Romans first landed. Roman glassware and silverware have been discovered at Chinese archaeological sites dated to the Han period (202 BC to 220 AD). Roman coins and glass beads have also been found in the Japanese archipelago.

The Hoxne Hoard (/ˈhɒksən/ HOK-sən) is the largest hoard of late Roman silver and gold discovered in Britain, and the largest collection of gold and silver coins of the fourth and fifth centuries found anywhere within the former Roman Empire. It was found by Eric Lawes using a metal detector in the village of Hoxne in Suffolk, England, in 1992. The hoard consists of 14,865 Roman gold, silver, and bronze coins and approximately 200 items of silver tableware and gold jewellery. The objects are now in the British Museum in London, where the most important pieces and a selection of the rest are on permanent display. In 1993, the Treasure Valuation Committee valued the hoard at £1.75 million (about £4.5 million in 2023).

The hoard was buried in an oak box or small chest filled with items in precious metal, sorted mostly by type, with some in smaller wooden boxes and others in bags or wrapped in fabric. Remnants of the chest and fittings, such as hinges and locks, were recovered in the excavation. The coins of the hoard date it after AD 407, which coincides with the end of Britain as a Roman province. The owners and reasons for burial of the hoard are unknown, but it was carefully packed and the contents appear consistent with what a single very wealthy family might have owned. It is likely that the hoard represents only a part of the wealth of its owner, given the lack of large silver serving vessels and some of the most common types of jewellery.

The Year of the Six Emperors was the year AD 238, during which six men made claims to be emperors of Rome. This was an early symptom of what historians now call the Crisis of the Third Century (AD 235–285), a period in which the Roman Empire nearly collapsed under the combined pressures of foreign invasions and migrations into the Roman territory, plagues, civil wars, peasant rebellions, political instability (with multiple usurpers competing for power), Roman reliance on (and growing influence of) foreign mercenaries known as foederati and commanders nominally working for Rome (but increasingly independent), the devastating social and economic effects of the plague, debasement of currency, and economic depression. The crisis ended with the final victory of Diocletian and his implementation of reforms in 285.

The Year of the Six Emperors may be called the Year of the Seven Emperors if Gaius Julius Verus Maximus, the son of Maximinus Thrax is counted. He bore the title caesar but not augustus. Edward Gibbon, in his History of the Decline and Fall of the Roman Empire, includes Maximus when he notes how "in the space of a few months, six princes had been cut off by the sword", before Gordian III became sole emperor.

The uncia (Latin; lit. 'twelfth part') was a Roman currency worth one twelfth of an as.

The Government Museum, Chennai, or the Madras Museum, is a museum of human history and culture located in the Government Museum Complex in the neighbourhood of Egmore in Chennai, India. Started in 1851, it is the second oldest museum in India after the Indian Museum in Kolkata. It has among the largest collection of Roman currency outside Europe. The Museum Theatre is a central landmark of the museum. The National Art Gallery is also present in the museum premises. Built in Indo-Saracenic style, it houses rare European and Asian painting of renowned artists, including Raja Ravi Varma. It had 600,000 visitors in 2018. It has a large collection of bronze idols, 500 of them dating to 1000 BCE, in Asia.

In ancient Roman culture, felicitas (from the Latin adjective felix, "fruitful, blessed, happy, lucky") is a condition of divinely inspired productivity, blessedness, or happiness. Felicitas could encompass both a woman's fertility and a general's luck or good fortune. The divine personification of Felicitas was cultivated as a Roman goddess, wherein she is a goddess not just of good fortune but also happiness, wealth and success. Although felicitas may be translated as "good luck," and the goddess Felicitas shares some characteristics and attributes with Fortuna, the two were distinguished in Roman religion. Fortuna was unpredictable and her effects could be negative, as the existence of an altar to Mala Fortuna ("Bad Luck") acknowledges. Felicitas, however, always had a positive significance. She appears with several epithets that focus on aspects of her divine power.

Felicitas had a temple in Rome as early as the mid-2nd century BC, and during the Republican era was honored at two official festivals of Roman state religion, on July 1 in conjunction with Juno and October 9 as Fausta Felicitas. Felicitas continued to play an important role in Imperial cult, and was frequently portrayed on coins as a symbol of the wealth and prosperity of the Roman Empire. Her primary attributes are the caduceus and cornucopia. The English word "felicity" derives from felicitas.

The economy of the ancient Tamil country (Sangam era: 600 BCE – 300 CE) describes the ancient economy of a region in southern India that mostly covers the present-day states of Tamil Nadu and Kerala. The main economic activities were agriculture, weaving, pearl fishery, manufacturing and construction. Rice was the most important crop; it was the staple cereal, grown widely in paddy fields, and served as a medium of exchange for inland trade. Pepper, millets, pulses and sugarcane were other commonly grown crops. Madurai and Urayur were important centres for the textile industry; Korkai was the center of the pearl trade. Industrial activity flourished.

Inland trading was conducted primarily through barter in busy market places by merchant associations and commercial lending institutions. Merchants formed associations that operated autonomously, without interference from the state. The people of ancient Tamil country engaged in brisk overseas trade with Rome; the trade reached a peak after the discovery of a direct route for merchant ships between Tamilakam and Egypt, taking advantage of the monsoon winds. Pepper, pearls, ivory, textiles and gold ornaments were exported from Tamilakam, and the main imports were luxury goods such as glass, coral, wine and topaz. Foreign trade brought in a large amount of internationally convertible Roman currency.

In architecture, an antefix (from Latin antefigere 'to fasten before') is a vertical block which terminates and conceals the covering tiles of a tiled roof (see imbrex and tegula, monk and nun). It also serves to protect the join from the elements. In grand buildings, the face of each stone antefix was richly carved, often with the anthemion ornament. In less grand buildings moulded ceramic antefixes, usually terracotta, might be decorated with figures heads, either of humans, mythological creatures, or astrological iconography, especially in the Roman period. On temple roofs, maenads and satyrs were often alternated. The frightening features of the Gorgon, with its petrifying eyes and sharp teeth, was also a popular motif to ward off evil. A Roman example from the Augustan period features the butting heads of two billy goats. It may have had special significance in imperial Rome since the constellation Capricorn was adopted by the emperor Augustus as his own lucky star sign and appeared on coins and legionary standards. By this time they were found on many large buildings, including private houses. The earliest examples in museum collections date back to the 7th century BCE in both Greece and Etruria.

In the garden of the Villa Giulia in Rome, that houses the National Etruscan Museum, is a reconstruction of an Etruscan temple built between 1889 and 1890 on the basis of the ruins found in Alatri. Its tiled roof is lined with antefixes.
