Pompeii in the context of "Neoclassical sculpture"

In the study of history as an academic discipline, a primary source (also called an original 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.In journalism, a primary source can be a person with direct knowledge of a situation, or a document written by such a person.

Primary sources are distinguished from secondary sources, which cite, comment on, or build upon primary sources. Generally, accounts written after the fact with the benefit of hindsight are secondary. A secondary source may also be a primary source depending on how it is used. For example, a memoir would be considered a primary source in research concerning its author or about their friends characterized within it, but the same memoir would be a secondary source if it were used to examine the culture in which its author lived. "Primary" and "secondary" should be understood as relative terms, with sources categorized according to specific historical contexts and what is being studied.

In Greek mythology, Patroclus (generally pronounced /pəˈtroʊkləs/; Ancient Greek: Πάτροκλος, romanized: Pátroklos, lit. 'glory of the father') was a Greek hero of the Trojan War and close companion to the hero Achilles. Patroclus is an important character in Homer's Iliad.

Born in Opus, Patroclus was the son of the Argonaut Menoetius. When he was a child, he was exiled from his hometown and was adopted by Peleus, king of Phthia. There, he was raised alongside Peleus's son, Achilles. When the tide of the Trojan War turned against the Achaeans, Patroclus, disguised as Achilles and defying his orders to retreat in time, led the Myrmidons in battle against the Trojans and was eventually killed by the Trojan prince, Hector. Enraged by Patroclus's death, Achilles ended his refusal to fight, resulting in significant Greek victories.

In Greek mythology, Hector (/ˈhɛktər/; Ἕκτωρ, Hektōr, pronounced [héktɔːr]) was a Trojan prince, a hero, and the greatest warrior for Troy during the Trojan War. He is a major character in Homer's Iliad, where he leads the Trojans and their allies in the defense of Troy, killing countless Greek warriors. He is ultimately killed in single combat by the Greek hero Achilles, who proceeds to drag his dead body around the city of Troy behind his chariot.

In Greek mythology, Neoptolemus (/ˌniːəpˈtɒlɪməs/; Ancient Greek: Νεοπτόλεμος, romanized: Neoptólemos, lit. 'new warrior'), originally called Pyrrhus at birth (/ˈpɪrəs/; Πύρρος, Pýrrhos, 'red'), was the son of the mythical warrior Achilles and the princess Deidamia, and the brother of Oneiros. He became the progenitor of the ruling dynasty of the Molossians of ancient Epirus. In a reference to his pedigree, Neoptolemus was sometimes called Achillides (from his father Achilles' name) or, from his grandfather's or great-grandfather's names, Pelides or Aeacides. According to Plutarch, Neoptolemus was the ancestor of Pyrrhus of Epirus.

Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the god of freshwater and the sea in the Roman religion. He is the counterpart of the Greek god Poseidon. In the Greek-inspired tradition, he is a brother of Jupiter and Pluto, with whom he presides over the realms of heaven, the earthly world (including the underworld), and the seas. Salacia is his wife.

Depictions of Neptune in Roman mosaics, especially those in North Africa, were influenced by Hellenistic conventions. He was likely associated with freshwater springs before the sea; his festival, Neptunalia, took place on July 23, during the peak of summer when water was scarcest. Like Poseidon, he was also worshipped by the Romans as a god of horses, Neptunus equestris, who was also a patron of horse-racing.

Heracles (/ˈhɛrəkliːz/ Ancient Greek: Ἡρακλῆς, lit. 'glory/fame of Hera'), born Alcaeus (Ἀλκαῖος, Alkaios) or Alcides (Ἀλκείδης, Alkeidēs), was a divine hero in Greek mythology, the son of Zeus and Alcmene, and the foster son of Amphitryon. He was a descendant of Perseus, another son of Zeus.

He was the greatest of the Greek heroes, the ancestor of royal clans known as Heracleidae (Ἡρακλεῖδαι), and a champion of the Olympian order against chthonic monsters. In Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. Details of his cult were adapted to Rome as well.

Penelope (/pəˈnɛləpi/ pə-NEL-ə-pee; Ancient Greek: Πηνελόπεια, Pēnelópeia, or Πηνελόπη, Pēnelópē) is a character in Homer's Odyssey. She was the queen of Ithaca and was the daughter of Spartan king Icarius and Asterodia. The mythological Penelope is known for her fidelity to her husband Odysseus, despite the attention of more than a hundred suitors during his absence. In one source, Penelope's original name was Arnacia or Arnaea.

Juno (English: /ˈdʒuːnoʊ/ JOO-noh; Latin: Iūnō [ˈjuːnoː]) is a goddess in the ancient Roman religion, the protector and special counsellor of the state. She equates to Hera, queen of the gods in Greek mythology and a goddess of love and marriage. A daughter of Saturn and Ops, she is the sister and wife of Jupiter and the mother of Mars, Vulcan, Bellona, Lucina and Juventas. Like Hera, her sacred animal is the peacock. Her Etruscan counterpart is Uni, and she was said to also watch over the women of Rome. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("Queen") and is a member of the Capitoline Triad (Juno Capitolina), centered on the Capitoline Hill in Rome, with also includes Jupiter, and Minerva, goddess of wisdom.

Juno's own warlike aspect among the Romans is apparent in her attire. She was often shown armed and wearing a goatskin cloak. The traditional depiction of this warlike aspect was assimilated from the Greek goddess Athena, who bore a goatskin, or a goatskin shield, called the Aegis. Juno was also shown wearing a diadem.

Cleopatra VII, the last ruler of the Ptolemaic Kingdom of Egypt, died on either 10 or 12 August, 30 BC, in Alexandria, when she was 39 years old. According to popular belief, Cleopatra killed herself by allowing an asp (Egyptian cobra) to bite her, but according to the Roman-era writers Strabo, Plutarch, and Cassius Dio, Cleopatra poisoned herself using either a toxic ointment or by introducing the poison with a sharp implement such as a hairpin. Modern scholars debate the validity of ancient reports involving snakebites as the cause of death and whether she was murdered. Some academics hypothesize that her Roman political rival Augustus (Octavian) forced her to kill herself in a manner of her choosing. The location of Cleopatra's tomb is unknown. It was recorded that Octavian allowed for her and her husband, the Roman politician and general Mark Antony, who stabbed himself with a sword, to be buried together properly.

Cleopatra's death effectively ended the final war of the Roman Republic between the remaining triumvirs Octavian and Antony, in which Cleopatra aligned herself with Antony, father to three of her children. Antony and Cleopatra fled to Egypt following their loss at the 31 BC Battle of Actium in Roman Greece, after which Octavian invaded Egypt and defeated their forces. Committing suicide allowed her to avoid the humiliation of being paraded as a prisoner in a Roman triumph celebrating the military victories of Octavian, who would become Rome's first emperor in 27 BC and be known as Augustus. Octavian, rival heir of Julius Caesar had Cleopatra's son Caesarion (also known as Ptolemy XV) killed in Egypt but spared her children with Antony and brought them to Rome. Cleopatra's death marked the end of the Hellenistic period and Ptolemaic rule of Egypt, as well as the beginning of Roman Egypt, which became a province of the Roman Empire.
