Document 2: Augustus (Williams novel): Born Gaius Octavius Thurinus, the young future-emperor was adopted by his great-uncle, Julius Caesar, after demonstrating promising wit and skill. After his great-uncle's assassination, Augustus (at this time known as Gaius Julius Caesar Octavianus) took vengeance upon Caesar's murderers, and through tactical political moves, became one of Rome's three “Triumvirs" alongside Marc Antony and Marcus Aemilius Lepidus. After defeating the other two triumvirs, and obtaining sole power over the Roman State, Augustus (known as "Imperator" Caesar Divi Filius), began taking measures to secure and increase his power. As a result, Augustus gave orders to exterminate Cleopatra's teenaged son, allegedly commenting, "too many Caesars is no good thing." (As it was the common belief that her son was of Julius Caesar's bloodline.) In light of such orders, Cleopatra and Marc Antony—lovers at the time—committed suicide.

He was the younger brother of Titus and son of Vespasian, his two predecessors on the throne, and the last member of the Flavian dynasty.

A member of the Julio-Claudian dynasty, he was the son of Drusus and Antonia Minor. He was born at Lugdunum in Gaul, the first (and until Trajan, the only) Roman Emperor to be born outside Italy. Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37.
Document 5: Publius Aelius Hadrianus Afer: Publius Aelius Hadrianus Afer was a distinct and wealthy Roman Senator and soldier who lived in the Roman Empire during the 1st century.

He came from a well-established, wealthy and aristocratic family of Praetorian rank. He was the son of the noble Roman woman called Ulpia and his father was a Roman Senator called Publius Aelius Hadrianus Marullinus. Hadrianus Afer’s maternal uncle was the Roman General and Senator Marcus Ulpius Traianus, the father of Ulpia Marciana and her younger brother Emperor Trajan.

Document 6: Britannicus: Tiberius Claudius Caesar Britannicus (ca. 12 February AD 41 – 11 February AD 55), usually called Britannicus, was the son of Roman emperor Claudius and his third wife Valeria Messalina. For a time he was considered his father's heir, but that changed after his mother's downfall in 48, when it was revealed she had a bigamous wedding behind Claudius' back. The next year, his father married Agrippina the Younger, Claudius' fourth and final marriage. Their marriage was followed by the adoption of Agrippina's son, Lucius Domitius, whose name became Nero as a result. His step-brother would later be married to his sister Octavia, and soon eclipsed him. Following his father's death in October 54, Nero became emperor. He was murdered by Nero sometime on or before 11 February 55, his fourteenth birthday.

Document 8: Claudia Capitolina: Claudia Capitolina (Greek: η Κλαuδία Καπιτωλίνα ) was an Egyptian Greek woman who lived in the Roman Empire, in the 1st century and possibly in the 2nd century. Capitolina came from a distinguished family of Equestrian rank. She was born and raised in Alexandria, Egypt. Capitolina was the daughter and only child of Tiberius Claudius Balbilus by his unnamed wife. The cognomen "Capitolina", is probably from her maternal side. Her father was one of the highest magistrates of Equestrian rank that served in Rome. Balbilus was an astrologer and a learned scholar, who was later Prefect of Egypt. Capitolina’s paternal grandfather, was an Egyptian Greek Grammarian and Astrologer called Thrasyllus of Mendes or Tiberius Claudius Thrasyllus, who was a friend of the Roman Emperor Tiberius, while her paternal grandmother was Greek Princess Aka II of Commagene, who was a great, granddaughter of King Antiochus I Theos of Commagene.

It was named after the empress Faustina, the wife of Marcus Aurelius, who died there in a village, which her husband, by establishing a colony in it, raised to the rank of a town under the name of Faustinopolis. Hierocles assigns the place to Cappadocia Secunda, and it is mentioned also in the Antonine and Jerusalem Itineraries. The town was close to the defiles of the Cilician Gates, and was likely situated at modern-day Toraman, Niğde Province, Turkey. Following the Muslim conquests and the subsequent Arab raids, the site was abandoned for the nearby fortress of Loulon.
Document 10: Tacitus: Publius (or Gaius) Cornelius Tacitus ( ; ] ;  56 AD –  120 AD ) was a senator and a historian of the Roman Empire. The surviving portions of his two major works—the "Annals" and the "Histories"—examine the reigns of the Roman emperors Tiberius, Claudius, Nero, and those who reigned in the Year of the Four Emperors (69 AD). These two works span the history of the Roman Empire from the death of Augustus, in 14 AD, to the years of the First Jewish–Roman War, in 70 AD. There are substantial lacunae in the surviving texts, including a gap in the "Annals" that is four books long.
Document 11: Claudiopolis (Cappadocia): Claudiopolis (Greek: Κλαυδιόπολις , "city of Claudius") was an ancient city of Cappadocia mentioned by Pliny (v. 24). From its name one can adduce that it was named for Roman emperor Claudius.
Document 12: Drusus Caesar: Drusus Caesar (Latin: "Drusus Iulius Caesar Germanicus" , AD 7 – AD 33) was a member of the Julio-Claudian dynasty in the early first century AD. He was the second son of Germanicus and Agrippina the Elder. After the death of his cousin Drusus the Younger in AD 23, he and his brother Nero were promoted by the emperor Tiberius as his heirs. Their progression would be short lived: in AD 29, the feud between his family and the powerful Praetorian Prefect Sejanus led to their downfall. First, his mother and Nero were exiled, and later Drusus was imprisoned in AD 30. Their deaths allowed Germanicus' third son, Caligula, to become Rome's third emperor following the death of Tiberius in 37.
Document 13: Augustus: Augustus (Latin: "Imperātor Caesar Dīvī Fīlius Augustus" ; 23 September 63 BC – 19 August 14 AD) was the founder of the Roman Principate and considered the first Roman emperor, controlling the Roman Empire from 27 BC until his death in AD 14. He was born Gaius Octavius into an old and wealthy equestrian branch of the plebeian "gens" Octavia. His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar's will as his adopted son and heir, then known as Octavianus (Anglicized as Octavian). He, Mark Antony, and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at the Battle of Philippi, the Triumvirate divided the Roman Republic among themselves and ruled as military dictators. The Triumvirate was eventually torn apart by the competing ambitions of its members. Lepidus was driven into exile and stripped of his position, and Antony committed suicide following his defeat at the Battle of Actium by Octavian in 31 BC.
Document 14: Saint Claudia: Saint Claudia is a saint and a mother of later Pope Linus. Her father, British King Caratacus led the British resistance, and later got chained after being defeated by Aulus Plautius. After emperor Claudius set him free, she took a name of "Claudia" and was baptized as such in Rome. She was mentioned in a second letter to Timothy which he received from Saint Paul. Second Timothy is generally viewed as Paul's last letter, and Claudia's name in 2 Timothy 4:21 appears as the last name of the letter and, hence, the last person Paul names in writing. It is also believed to be that Claudia was actually a daughter of Claudius Cogidubnus who was Claudius's ally and later became an emperor. He mentions that her real name was Claudia Rufina and she was married to Aulus Pudens, a friend of Martials. Her feast day is on August 7.
