Quintus Curtius Rufus

Marcus Aurelius Antoninus was Roman emperor from 161 to 180 AD and a Stoic philosopher. He was the last of the rulers known as the Five Good Emperors, and the last emperor of the Pax Romana, an age of relative peace, calmness and stability for the Roman Empire lasting from 27 BC to 180 AD. He served as Roman consul in 140, 145, and 161.

The Parthian Empire, also known as the Arsacid Empire, was a major Iranian political and cultural power in ancient Iran from 247 BC to 224 AD. Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (r. c. 171–132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids. At its height, the Parthian Empire stretched from the northern reaches of the Euphrates, in what is now central-eastern Turkey, to present-day Afghanistan and western Pakistan. The empire, located on the Silk Road trade route between the Roman Empire in the Mediterranean Basin and the Han dynasty of China, became a center of trade and commerce.

The Antonine Plague of AD 165 to 180, also known as the Plague of Galen, was the first known pandemic impacting the Roman Empire, possibly contracted and spread by soldiers who were returning from campaign in the Near East. Scholars generally believe the plague was smallpox, although measles has also been suggested. In AD 169 the plague may have claimed the life of the Roman emperor Lucius Verus, who was co-regnant with Marcus Aurelius. These two emperors had risen to the throne by virtue of being adopted by the previous emperor, Antoninus Pius, and as a result, their family name, Antoninus, has become associated with the pandemic.

Legio III Gallica was a legion of the Imperial Roman army. The cognomen Gallica suggests that its earliest recruits came from veterans of the Gallic legions of Gaius Julius Caesar, a supposition supported by its emblem, a bull, a symbol associated with Caesar. The legion was based for most of its existence at Raphanea, Roman Syria, and was still active in Egypt in the early 4th century.

Caesar Augustus, also known as Octavian, was the first Roman emperor; he reigned from 27 BC until his death in AD 14. He is known for being the founder of the Roman Principate, which is the first phase of the Roman Empire, and is considered one of the greatest leaders in human history. The reign of Augustus initiated an imperial cult as well as an era associated with imperial peace, the Pax Romana or Pax Augusta. The Roman world was largely free from large-scale conflict for more than two centuries despite continuous wars of imperial expansion on the empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

Caligula, formally known as Gaius, was the third Roman emperor, ruling from AD 37 until his assassination in AD 41. He was the son of the Roman general Germanicus and Agrippina the Elder, Augustus' granddaughter. Caligula was born into the first ruling family of the Roman Empire, conventionally known as the Julio-Claudian dynasty.

The Praetorian Guard was an elite unit of the Imperial Roman army that served as personal bodyguards and intelligence agents for the Roman emperors. During the Roman Republic, the Praetorian Guard were an escort for high-rank political officials and were bodyguards for the senior officers of the Roman legions. In 27 BC, after Rome's transition from republic to empire, the first emperor of Rome, Augustus, designated the Praetorians as his personal security escort. For three centuries, the guards of the Roman emperor were also known for their palace intrigues, by which influence upon imperial politics the Praetorians could overthrow an emperor and then proclaim his successor as the new caesar of Rome. In AD 312, Constantine the Great disbanded the cohortes praetoriae and destroyed their barracks at the Castra Praetoria.

Tiberius Claudius Caesar Augustus Germanicus was the fourth Roman emperor, ruling from AD 41 to 54. A member of the Julio-Claudian dynasty, Claudius was born to Drusus and Antonia Minor at Lugdunum in Roman Gaul, where his father was stationed as a military legate. He was the first Roman emperor to be born outside Italy. Nonetheless, Claudius was an Italian of Sabine origins.

The gens Curtia was an ancient but minor noble family at Rome, with both patrician and plebeian branches. The only member of the gens invested with the consulship under the Republic was Gaius Curtius Philo, in 445 BC. A few Curtii held lesser magistracies during the Republic, and there were two consuls suffectus in imperial times. However, the gens is best remembered from a series of legends dating from the traditional founding of the city to the early Republic.

Adoption in ancient Rome was practiced and performed by the upper classes; a large number of adoptions were performed by the Senatorial class. Succession and family legacy were very important; therefore, Romans needed ways of passing down their fortune and name when unable to produce a male heir. Adoption was one of the few ways to guarantee succession, so it became a norm to adopt young males into the homes of high ranking families. Due to the Roman inheritance laws, women had very little rights or the ability to inherit fortunes. This made them less valuable for adoption. However, women were still adopted and it was more common for them to be wed to an influential family.

The Histories of Alexander the Great is the only surviving extant Latin biography of Alexander the Great. It was written by the Roman historian Quintus Curtius Rufus in the 1st-century AD, but the earliest surviving manuscript comes from the 9th century.

The codex was the historical ancestor of the modern book. Instead of being composed of sheets of paper, it used sheets of vellum, papyrus, or other materials. The term codex is often used for ancient manuscript books, with handwritten contents. A codex, much like the modern book, is bound by stacking the pages and securing one set of edges by a variety of methods over the centuries, yet in a form analogous to modern bookbinding. Modern books are divided into paperback or softback and those bound with stiff boards, called hardbacks. Elaborate historical bindings are called treasure bindings. At least in the Western world, the main alternative to the paged codex format for a long document was the continuous scroll, which was the dominant form of document in the ancient world. Some codices are continuously folded like a concertina, in particular the Maya codices and Aztec codices, which are actually long sheets of paper or animal skin folded into pages.

A manuscript was, traditionally, any document written by hand or typewritten, as opposed to mechanically printed or reproduced in some indirect or automated way. More recently, the term has come to be understood to further include any written, typed, or word-processed copy of an author's work, as distinguished from the rendition as a printed version of the same.

A lacuna is a gap in a manuscript, inscription, text, painting, or musical work. A manuscript, text, or section suffering from gaps is said to be "lacunose" or "lacunulose".

The High Middle Ages, or high medieval period, was the period of European history that lasted from AD 1000 to 1300. The High Middle Ages were preceded by the Early Middle Ages and were followed by the Late Middle Ages, which ended around AD 1500.

The Alexander Romance is an account of the life and exploits of Alexander the Great. Although constructed around a historical core, the romance is mostly fictional. It was widely copied and translated, accruing various legends and fantastical elements at different stages. The original version was composed in Ancient Greek some time before 338 CE, when a Latin translation was made, although the exact date is unknown. Several late manuscripts attribute the work to Alexander's court historian Callisthenes, but Callisthenes died before Alexander and therefore could not have written a full account of his life. The unknown author is still sometimes known as Pseudo-Callisthenes.

The Alexandreis is a medieval Latin epic poem by Walter of Châtillon, a 12th-century French writer and theologian. It gives an account of the life of Alexander the Great, based on Quintus Curtius Rufus' Historia Alexandri Magni. The poem was popular and influential in Walter's own times: according to Henry of Ghent, it was more popular than Virgil's Aeneid in thirteenth-century schools. Translations were made into Old Spanish, Middle Dutch into Old Norse as the Alexanderssaga; Matthew of Vendôme and Alan of Lille borrowed from it and Henry of Settimello imitated it, but it is now seldom read. One line is sometimes quoted:Incidis in Scyllam cupiens vitare Charybdim (V.301).

The Aeneid is a Latin epic poem, written by Virgil between 29 and 19 BC, that tells the legendary story of Aeneas, a Trojan who fled the fall of Troy and travelled to Italy, where he became the ancestor of the Romans. It comprises 9,896 lines in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas' wanderings from Troy to Italy, and the poem's second half tells of the Trojans' ultimately victorious war upon the Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed.

Paolo Caliari, known as Paolo Veronese, was an Italian Renaissance painter based in Venice, known for extremely large history paintings of religion and mythology, such as The Wedding at Cana (1563) and The Feast in the House of Levi (1573). Included with Titian, a generation older, and Tintoretto, a decade senior, Veronese is one of the "great trio that dominated Venetian painting of the cinquecento" and the Late Renaissance in the 16th century. Known as a supreme colorist, and after an early period with Mannerism, Paolo Veronese developed a naturalist style of painting, influenced by Titian.

Charles Le Brun was a French painter, physiognomist, art theorist, and a director of several art schools of his time. As court painter to Louis XIV, who declared him "the greatest French artist of all time", he was a dominant figure in 17th-century French art and much influenced by Nicolas Poussin.

In the study of history as an academic discipline, a primary source is an artifact, document, diary, manuscript, autobiography, recording, or any other source of information that was created at the time under study. It serves as an original source of information about the topic. Similar definitions can be used in library science and other areas of scholarship, although different fields have somewhat different definitions.
