Maritime East Asia (333–190 BCE): Qin Unification and Philosophical Consolidation

Between 333 BCE and 190 BCE, Maritime East Asia—comprising lower Primorsky Krai, the Korean Peninsula, the Japanese Archipelago below northern Hokkaido, Taiwan, and southern, central, and northeastern China—experiences transformative political unification under the Qin dynasty and significant philosophical and technological developments, setting the stage for imperial China.

Qin Unification and Imperial Foundations

In 221 BCE, the western frontier state of Qin achieves dominance, subjugating the rival Warring States and uniting much of what becomes China Proper. The victorious Qin ruler takes the unprecedented title of Shi Huangdi (First Emperor), centralizing administration through a bureaucratic system that replaces hereditary rule. The Qin empire standardizes legal codes, writing systems, currency, and administrative practices, creating a unified state apparatus.

To consolidate power, the Qin emperors ruthlessly suppress dissent, persecuting Confucian scholars, destroying Confucian texts, and exiling or executing dissidents. Military campaigns expand territorial control northward and southward, while the defensive walls of former states are unified into an extensive fortification, forming the precursor to the Great Wall. Despite these achievements, Qin rule is short-lived; following Shi Huangdi's death in 210 BCE, widespread revolts topple the dynasty by 206 BCE. Nevertheless, the centralized imperial structure established by the Qin endures, influencing Chinese governance for the next two millennia.

Legalism and the State

The Qin dynasty’s consolidation relies heavily on the Legalist philosophy, formulated by Han Feizi and Li Si, who emphasize the inherently selfish nature of humans and advocate strict laws and centralized power as the sole means to maintain social order. Legalism prioritizes state strength, military prowess, and administrative efficiency over individual welfare, becoming the philosophical backbone of the Qin government. Elements of Legalism, combined with Confucian ethics, later underpin the Han dynasty's enduring governmental framework.

Philosophical Traditions and Cultural Developments

Concurrent with Qin's political centralization, philosophical traditions from the Warring States period mature and diversify:

• Taoism (Daoism), articulated by legendary figures such as Lao Zi and later Zhuang Zi, emphasizes harmony with nature and individual adjustment to the universal Way (dao).

• The Yin-Yang and Five Elements philosophy emerges prominently, explaining cosmic and natural phenomena through complementary dualities and elemental interactions, significantly impacting both scholarly and popular thought.

• Mohism, founded by Mo Zi (Mo Di), promotes universal love, pacifism, utilitarianism, and strict social order. Though less dominant, Mohist thought leaves a lasting imprint on Chinese intellectual traditions.

Confucianism continues to evolve, with scholars such as Xunzi presenting a contrasting view to Mencius, arguing for humanity’s inherent selfishness and advocating education and strict authority to achieve social order.

Technological Innovations

Technological developments include early Chinese alchemists experimenting with mercury in attempts at metal transmutation, and notable advancements in mathematics and astronomy. The Zhou Bi Suan Jing, a pivotal mathematical text, emerges during this era, featuring astronomical calculations and providing one of the earliest proofs of the Gougu theorem (Pythagorean theorem). It also calculates an early value of pi, reflecting a sophisticated understanding of geometry and mathematics.

Cultural Influence in Korea

In the Korean Peninsula, archaeological findings from sites like Kŭmtan-ni near modern Pyongyang reveal extensive prehistoric occupation dating back to pottery cultures (Chŭlmun and Mumun periods). Pyongyang itself rises as a significant city during this era under the Gojoseon kingdom, historically identified as the capital Asadal (Wanggomsŏng), highlighting early Korean civilization’s roots.

Legacy of the Age: Foundations for Imperial China

Thus, the age from 333 to 190 BCE is characterized by Qin’s decisive political unification, foundational legalist doctrines, vibrant philosophical traditions, and notable technological advancements. These developments lay critical groundwork for the imperial era of Chinese history, influencing governance, philosophy, and culture profoundly for generations.

Alchemists in China apparently employ mercury in their attempts to convert base metals to gold as early as the second century BCE.

Mediterranean Southwest Europe (112–123 CE): Cultural Critique and Societal Reflections

The era 112–123 CE in Mediterranean Southwest Europe continues under the prosperous and stable rule of Emperor Trajan, highlighting significant cultural, social, and intellectual developments. Notably, the period features critical reflections on Roman society, epitomized by the influential satirical writings of Juvenal.

Juvenal and Roman Satire

During this period, the satirist Juvenal composes his impactful Satire 3, sharply criticizing contemporary Roman society by contrasting it with the moral integrity perceived to have characterized the early Roman Republic. Juvenal’s writings reflect broader societal anxieties, providing incisive commentary on issues of morality, civic responsibility, and political power.

Famous Maxims from Juvenal

Juvenal's satirical works offer enduring maxims that resonate through history, capturing key insights into Roman cultural attitudes and social commentary:

• "Bread and circuses" (panem et circenses): Highlighting public apathy toward civic freedom and moral decline, suggesting that citizens prioritize entertainment and sustenance over liberty and political involvement.

• "A sound mind in a sound body" (mens sana in corpore sano): Emphasizing the ideal balance of physical and mental health, reflecting Roman values on personal well-being and philosophical moderation.

• "A rare bird" (rara avis in terris nigroque simillima cycno): Commenting humorously yet sharply on the difficulty of finding the ideal partner, reflecting prevailing societal skepticism about marital fidelity and idealism.

• "Who will watch the watchers?" (quis custodiet ipsos custodes): Addressing fundamental concerns about accountability, power, and corruption, this maxim questions the reliability and integrity of those entrusted with authority.

Economic Stability and Cultural Prosperity

Economic prosperity persists under Trajan, facilitating continued cultural achievements and supporting extensive intellectual and artistic activities. Hispania, central to Rome’s economy, maintains robust trade networks, contributing significantly to the broader prosperity of Mediterranean Southwest Europe.

Mediterranean Southwest Europe (148–159 CE): Religious Debates and Roman Authority

The era 148–159 CE in Mediterranean Southwest Europe is notable for important religious developments and early indications of Rome's central role in Christian doctrinal discussions. This period highlights interactions between prominent early Christian figures and significant religious controversies.

Polycarp's Visit to Rome and the Paschal Controversy

During the pontificate of Pope Anicetus, the aged Polycarp of Smyrna, a disciple of John the Evangelist, visits Rome to discuss the celebration of Passover. Polycarp and the Church of Smyrna celebrate the crucifixion on the fourteenth day of Nisan, coinciding with the Jewish Passover, regardless of the weekday. In contrast, the Roman Church celebrates Pasch (Easter) on Sunday, commemorating Jesus' resurrection.

Although Polycarp and Anicetus fail to reach an agreement on a unified date for the celebration, Anicetus permits Polycarp and his church to maintain their traditional observance. This divergence initiates the Paschal controversy, which intensifies in subsequent centuries.

Visits by Hegesippus and Early Significance of the Roman See

The historian Hegesippus also visits Rome during Anicetus’s pontificate, reflecting the increasing prominence and importance of the Roman See in early Christian communities. This visit underscores the Roman Church's emerging role as a focal point of doctrinal and ecclesiastical authority.

Anicetus's Opposition to Heresies

Pope Anicetus actively opposes emerging religious movements perceived as heretical, notably Montanism, Gnosticism, and Marcionism. He becomes the first Roman bishop documented to explicitly condemn such teachings, reinforcing the doctrinal authority of Rome and setting precedents for ecclesiastical orthodoxy.

Additionally, Anicetus issues specific regulations, such as decreeing that priests must not have long hair—a measure possibly intended to distinguish orthodox clergy from Gnostic practitioners, known for wearing their hair long.

Mediterranean Southwest Europe (160–171 CE): Philosophical Engagements and Early Christian Debates

The era 160–171 CE in Mediterranean Southwest Europe is notable for significant philosophical and religious developments, marked by the influential reign of Marcus Aurelius, cultural advancements in art, and intense philosophical debates within the burgeoning Christian community.

Marcus Aurelius and Stoic Philosophy

During this period, Marcus Aurelius, already empowered as imperial heir and educated by prominent tutors in Rome and Athens, embraces Stoicism. His philosophical transition from rhetoric to Stoicism profoundly shapes his reign, emphasizing rational self-control, ethical reflection, and the pursuit of virtue, significantly influencing Roman intellectual and cultural life.

Artistic Innovations: Roman Sarcophagi

Artistic expression continues to flourish, notably through the sophisticated "Roman type" sarcophagi, exemplified by the Niobid Sarcophagus (ca. 160–170 CE). These sarcophagi, carved in high relief with intricate representations of mythological scenes, battles, and decorative garlands, underscore the cultural sophistication and artistic accomplishments of the era.

Justin Martyr and Christian Apologetics

The Samaritan Christian theologian Justin Martyr, well-versed in Stoic, Peripatetic, Pythagorean, and Platonic traditions, significantly contributes to Christian intellectual discourse. Justin emigrates to Rome during the reign of Antoninus Pius, where he establishes a philosophical school and authors influential treatises, notably his two Apologies, Dialogue with Trypho, and On the Resurrection.

In 165 CE, after public philosophical disputes, particularly with the cynic philosopher Crescens, Justin and six companions are tried by Junius Rusticus, the urban prefect, and subsequently executed. The martyrdom of Justin preserves crucial historical records of early Christian persecution and doctrinal defense.

Tatian’s Influence and Controversial Legacy

One of Justin’s prominent pupils, Tatian, an ethnic Assyrian who encounters Christianity in Rome, emerges as a significant yet controversial figure. Rejecting pagan practices and convinced by Old Testament writings, Tatian converts to Christianity and opens his own philosophical school in Rome.

Following Justin's martyrdom, Tatian becomes involved in theological controversies, notably espousing Encratitic (ascetic) views and reportedly associating with Gnostic leader Valentinius. His subsequent expulsion from the orthodox community prompts him to leave Rome. Later sources suggest Tatian establishes a school in Mesopotamia with notable influence across Syria, Cilicia, and Pisidia, although these accounts remain uncertain.

Tatian authors influential works, notably the Oratio ad Graecos, a discursive critique of paganism asserting Christianity's ancient and rational foundations. His Diatessaron, a harmonized narrative synthesizing the four canonical Gospels, becomes widely influential, especially in Syria during the third and fourth centuries.

Cultural Continuity and Intellectual Life

This period maintains robust cultural and intellectual vitality under Antoninus Pius and Marcus Aurelius. Literary, philosophical, and artistic endeavors flourish, demonstrating the era’s sophisticated engagement with diverse intellectual traditions and philosophical debates.

Diocletian, in an attempt to prevent counterfeiting, orders the burning of all texts dealing with gold-, silver- and copper-working; this proscription, however, fans an increased interest in alchemy and magic as ways of transmuting base metal to gold.

He introduces direct control of wages and prices in 301 with his issuance of the Edict on Maximum Prices, which, rather than halting rampant inflation and stabilizing the economy, adds to inflationary pressures by flooding the economy with new coinage and by setting price limits too low.
