Tacitus in the context of "Bastarnae"

During the Second Punic War with Carthage, Rome's earliest known annalists Quintus Fabius Pictor and Lucius Cincius Alimentus recorded history in Greek, and relied on Greek historians such as Timaeus. Roman histories were not written in Classical Latin until the 2nd century BCE with the Origines by Cato the Elder. Contemporary Greek historians such as Polybius wrote about the rise of Rome during its conquest of Greece and ascension as the primary power of the Mediterranean in the 2nd century BCE. Moving away from the annalist tradition, Roman historians of the 1st century BCE such as Sallust, Livy, and even Julius Caesar wrote their works in a much fuller narrative form. While Caesar's De Bello Gallico focused specifically on his wars in Gaul, Roman works that served as a broad universal history often placed heavy emphasis on the origin myth of the founding of Rome as a starting point. These works formed the basis of the Roman historiographic models utilized by later Imperial authors of the Principate era, such as Tacitus and Suetonius.

Early Greek cosmology refers to beliefs about the origins, development, and structure of the universe in Ancient Greece that existed before the development of Ancient Greek astronomy. The basic elements of this early cosmology included a flat earth, heaven, a cosmic ocean, the afterworld (Hades), and the netherworld (Tartarus). The first three were represented by the gods Gaia, Uranus, and Oceanus (or sometimes Pontus). Ancient Greek cosmology was related to ancient Near Eastern cosmology, and was ultimately replaced by a more systematic and demythologized approach found in ancient Greek astronomy. Its main sources are the poetry of Homer (the Iliad and the Odyssey), Hesiod (the Theogony and the Works and Days), and surviving fragments from Mimnermus.

Beginning in the 5th century BC, elements of the traditional Greek cosmos began to be modified and challenged. One of the earliest of these challenges came from the emergence of the view that the cosmos as a whole was spherical (advocated by Xenophanes, Parmenides, Empedocles, and others). The rotation of the spherical cosmos was said to explain the visible rotation of the stars (an idea called "vortex"). Soon, a spherical model of the earth itself was proposed, which gradually gained acceptance, although the flat earth view never entirely disappeared during either classical antiquity or late antiquity, continuing to receive support from geographers and others like Ctesias, Ephorus, Strabo, Tacitus, and the Epicureans. The last Greek advocate of the traditional cosmology was Cosmas Indicopleustes.

Gaius Plinius Secundus (23 or 24 CE - 25 August 79 CE), known in English as Pliny the Elder (/ˈplɪni/ PLIN-ee), was a Roman author, naturalist, scientist, naval and army commander of the early Roman Empire, and friend of the emperor Vespasian. Pliny wrote the encyclopedic Naturalis Historia (Natural History), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field.

Among Pliny's greatest works was the twenty-volume Bella Germaniae ("Wars of Germania"), which is no longer extant. Bella Germaniae, which began where Aufidius Bassus' writings on Germani wars left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used Bella Germaniae as the primary source for his work, De origine et situ Germanorum ("On the Origin and Situation of the Germani").

Early Christians were heavily persecuted throughout the Roman Empire until the 3rd century. Although Christianity initially emerged as a small Jewish movement in 1st-century Judaea, it quickly branched off as a separate religion and began spreading across the various Roman territories at a pace that put it at odds with the well-established Roman imperial cult, to which it stood in opposition; Christians were vocal in their expressions of abhorrence towards the beliefs and practices of Roman paganism, such as deifying and making ritual sacrifices to the Roman emperor or partaking in other methods of idolatry. Consequently, the Roman state and other members of civic society routinely punished Christians for treason, various rumoured crimes, illegal assembly, and for introducing an alien cult that drove many Roman people to apostasy in favour of Jesus Christ. According to Tacitus, the first wave of organized persecution occurred under Nero (r. 54–68), who blamed Christians for the Great Fire of Rome in 64. A number of mostly localized persecutions occurred during the reign of Marcus Aurelius (r. 161–180). After a lull, persecution resumed under Decius (r. 249–251) and Trebonianus Gallus (r. 251–253). The Decian persecution was particularly extensive, as Decius strived to restore the Roman golden age in part by forcing pagan practices upon the Christian community. Another wave of persecution began under Valerian (r. 253–260), but ceased abruptly after he was captured and taken prisoner by the Sasanian Empire during the Battle of Edessa of the Roman–Persian Wars. Under his successor Gallienus (r. 253–268), whose reign was marred by rapidly escalating military conflicts of the Crisis of the Third Century, the first ever decree of tolerance was issued for Christian practices and places of worship, although it stopped short of recognizing Christianity as a religion with legal status.

Emperor Diocletian (r. 283–305) began the Diocletianic persecution, which was the final and the most severe wave of persecution of Christians by the Roman state. It was enforced until the accession of Galerius (r. 305–311), who issued the Edict of Serdica, and the death of Maximinus Daza (r. 310–313). After Constantine the Great (r. 306–337) defeated his rival Maxentius (r. 306–312) at the Battle of the Milvian Bridge in October 312, he and his co-emperor Licinius issued the Edict of Milan, which decriminalized Christianity and suppressed pagan populations throughout the Roman Empire. In 380, Theodosius I (r. 379–395) issued the Edict of Thessalonica, officially establishing Christianity as the Roman state religion. It was also during the reign of Theodosius I that pagan practices were overtly deemed punishable offenses, which laid the framework for early Byzantine anti-pagan policies.

Decimus Laelius Balbus was a Roman senator and delator or informer, active during the Principate. He was suffect consul in the nundinium of July-August 46 as the colleague of Marcus Junius Silanus.

His father has been identified as Decimus Laelius Balbus, consul in 6 BC. Balbus himself first enters history when in AD 37 he accused Acutia, the former wife of Publius Vitellius, of maiestas. Following her conviction, when the Senate voted on his reward, the plebeian tribune Junius Otho interposed with his veto. According to Tacitus, this gave rise to a feud between Vitellius and Otho which ended in Otho's banishment. That same year, Balbus was accused along with Albucilla, "notorious for the number of her lovers", was deprived of his rank as senator and exiled to an island, which was received "with intense satisfaction, as Balbus was noted for his savage eloquence and his eagerness to assail the innocent."

The term victory (from Latin: victoria) originally applied to warfare, and denotes success achieved in personal combat, after military operations in general or, by extension, in any competition. Success in a military campaign constitutes a strategic victory, while the success in a military engagement is a tactical victory.

In terms of human emotion, victory accompanies strong feelings of elation, and in human behaviour often exhibits movements and poses paralleling threat display preceding the combat, which are associated with the excess endorphin built up preceding and during combat.Victory dances and victory cries similarly parallel war dances and war cries performed before the outbreak of physical violence.Examples of victory behaviour reported in Roman antiquity, where the term victoria originated, include: the victory songs of the Batavi mercenaries serving under Gaius Julius Civilis after the victory over Quintus Petillius Cerialis in the Batavian rebellion of 69 AD (according to Tacitus); and also the "abominable song" to Wodan, sung by the Lombards at their victory celebration in 579. The sacrificial animal was a goat, around whose head the Langobards danced in a circle while singing their victory hymn.The Roman Republic and Empire celebrated victories with triumph ceremonies and with monuments such as victory columns (e.g. Trajan's Column) and arches. A trophy is a token of victory taken from the defeated party, such as the enemy's weapons (spolia), or body parts (as in the case of head hunters).

The Suebian knot (German: Suebenknoten) is a historical male hairstyle ascribed to the tribe of the Germanic Suebi. The knot is attested by Tacitus in his 1st century AD work Germania, found on contemporary depictions of Germanic peoples, their art, and bog bodies.

The Angles (Old English: Engle, Latin: Anglii) were one of the main Germanic peoples who settled in Great Britain in the post-Roman period. They founded several kingdoms of the Heptarchy in Anglo-Saxon England. Their name, which probably derives from the Angeln peninsula, is the root of the name England ("Engla land", "Land of the Angles"), and English, in reference to both for its people and language. According to Tacitus, writing around 100 AD, a people known as Angles (Anglii) lived beyond (apparently northeast of) the Langobards and Semnones, who lived near the River Elbe.
