Omen in the context of "Sacrificial lamb"

Augury was a Greco-Roman religious practice of observing the behavior of birds, to receive omens. When the individual, known as the augur, read these signs, it was referred to as "taking the auspices". "Auspices" (Latin: auspicium) means "looking at birds". Auspex, another word for augur, can be translated to "one who looks at birds". Depending upon the birds, the auspices from the gods could be favorable or unfavorable (auspicious or inauspicious). Sometimes politically motivated augurs would fabricate unfavorable auspices in order to delay certain state functions, such as elections. Pliny the Elder attributes the invention of auspicy to Tiresias the seer of Thebes.

Over the development of the Roman empire, the definition of augury broadened to include other forms of divination. Haruspicy—the examination of animal entrails—was learned from the Etruscans. The Etruscan practice of observing thunder and lightning was also adapted. In Cicero's time, the augurs had mostly switched from using the flight of birds to haruspicy for public divination.

Divination is the attempt to gain insight into a question or situation by way of a magic ritual or practice. Using various methods, throughout history, diviners have been providing answers to querents by reading signs, events, or omens, often receiving insight through supernatural agencies such as spirits, gods, god-like-beings or the "will of the universe".

Divination can be seen as an attempt to organize what appears to be random, so that it provides insight into a problem or issue at hand. Some practices of divination include astrology, Tarot card reading, rune casting, tea-leaf reading, Ouija boards, automatic writing, water scrying, numerology, pendulum divination and countless more. If a distinction is made between divination and fortune-telling, divination has a more formal or ritualistic element and often contains a more social character, usually in a religious context, as seen in traditional African medicine. Fortune-telling, on the other hand, is a more everyday practice for personal purposes. Particular divination methods vary by culture and religion.

Lucius Tarquinius Priscus (Classical Latin: [tarˈkʷɪniʊs ˈpriːskʊs]), or Tarquin the Elder, was the legendary fifth king of Rome and first of its Etruscan dynasty. He reigned for thirty-eight years. Tarquinius expanded Roman power through military conquest and grand architectural constructions. His wife was the prophetess Tanaquil.

Not much is known about the early life of Lucius Tarquinius Priscus. According to Livy, Tarquin came from Etruria. Livy claims that his original Etruscan name was Lucumo, but since lucumo is the latinized form of the Etruscan word lauchume "king", there is reason to believe that his name and title have been confused in the official tradition. After inheriting his father's entire fortune, Lucius attempted to gain a political office. However, he was prohibited from obtaining political office in Tarquinii because of the ethnicity of his father, Demaratus, who came from the Greek city of Corinth. As a result, his wife Tanaquil advised him to relocate to Rome. Legend has it that on his arrival in Rome in a chariot, an eagle took his cap, flew away and then returned it back upon his head. Tanaquil, who was skilled in prophecy, interpreted this as an omen of his future greatness. In Rome, he attained respect through his courtesy. King Ancus Marcius noticed Tarquinius and, by his will, appointed Tarquinius guardian of his own sons.

Gongsun Hong (公孫弘; Wade–Giles: Kung-sun Hung; 200 – 7 April 121 BCE) was a senior official in the Western Han dynasty under Emperor Wu. Together with the more famous Confucian scholar Dong Zhongshu, Gongsun was one of the earliest proponents of Confucianism, setting in motion its emergence under the Han court. The ideals and decrees both promoted would come to be seen as values-in-themselves, becoming the "basic elements, or even hallmarks" of Confucianism, although not necessarily officially during his lifetime. While first proposed and more ardently promoted by Dong, the national academy and Imperial examination, then considered radical, did not come into existence until they were supported by the more successful Gongsun. Their establishment set a precedent that would last into the twentieth century.

Gongsun was born in Zichuan within the Kingdom of Lu, part of present-day Shandong province. Beginning his political career at age sixty, he rapidly advanced from commoner to attain a senior appointment in 130BC when he was seventy, becoming grand secretary and 'censor-in-chief' in 126, and chancellor in 124. One of the Three Dukes, in recognition of canonical mastery he was probably the first Han Confucian to be appointed to high office, the first commoner and first (and only, out of twelve of the time) Confucian to be made chancellor, as well as the first chancellor to be made marquis. He set a precedent for Confucianism as interpreter of portents.

The crucifixion darkness is an event described in the synoptic gospels in which the sky becomes dark in daytime during the crucifixion of Jesus for roughly three hours. Most ancient and medieval Christian writers treated this as a miracle, and believed it to be one of the few episodes from the New Testament which were confirmed by non-Christian sources. Modern scholars have found references by early historians to accounts of this event outside the New Testament, although no copies of the referenced accounts survive.

In his Apologeticus, Christian apologist Tertullian in AD 197 considered this not an eclipse but an omen, which is recorded in Roman archives. In his apologetic work Contra Celsum, the third-century Christian scholar Origen offered two natural explanations for the darkness: that it might have been the eclipse described by Phlegon of Tralles in his Chronicle or that it might have been clouds. In his Chronicle of Theophanes the fifth-century chronicler George Syncellus quotes the History of the World of Sextus Julius Africanus as stating that a world eclipse and an earthquake in Judea had been reported by the Greek 1st century historian Thallus in his Histories.
