The Puranas, a genre of important Hindu, Jain and Buddhist religious texts, notably consisting of narratives of the history of the universe from creation to destruction, genealogies of kings, heroes, sages, and demigods, and descriptions of Hindu cosmology, philosophy, and geography, begin to be compiled about this time.
Vyasa, the narrator of the Mahabharata, is traditionally considered the compiler of the Puranas.
However, the earliest written versions date from the time of the Gupta Empire (third to fifth centuries CE) and much material may be dated, through historical references and other means, to this period and the succeeding centuries.
The texts were probably written all over India.
The date of the production of the written texts does not define the date of origin of the Puranas.
On one hand, they existed in some oral form before being written while at the same time, they have been incrementally modified well into the sixteenth century and perhaps down to the present day.
An early reference is found in the Chandogya Upanishad (7.1.2). (circa 500 BCE.)
The Brhadaranyaka Upanishad refers to purana as the "fifth Veda", itihāsapurāṇaṃ pañcamaṃ vedānāṃ, reflecting the early religious importance of these myths, presumably then in purely oral form.
Importantly, the most famous form of itihāsapurāṇaṃ is the Mahabharata.
The term also appears in the Atharvaveda 11.7.24.
According to Pargiter, the "original Purana" may date to the time of the final redaction of the Vedas.
Gavin Flood connects the rise of the written Purana historically with the rise of devotional cults centering upon a particular deity in the Gupta era: the Puranic corpus is a complex body of materials that advance the views of various competing cults.
Plato writes two dialogues in 356 BCE: the Timaeus and the Critias, the earliest known reference to Atlantis.
In the Timaeus, which presents a semi-mythical description of the origin and nature of the universe, Plato recounts the tale of Egyptian priests who two-hundred years earlier had reportedly described Atlantis as a powerful island empire seeking to dominate the Mediterranean world more than nine thousand years before Plato's time.
The Atlantans’ plans for expansion were ended only when Athens defeated their army.
Shortly afterward, a violent earthquake caused Atlantis to sink beneath the ocean.
Greatly influenced by Pythagorean number theory, Plato describes in the Timaeus the soul of the world as structured according to the musical ratios that the Pythagoreans see as governing forces in the cosmos as well as in sounds.
Plato applies the name Demiurge—the Greek word for artisan or craftsman—to God the creator, the divine craftsman who brought order out of a primeval chaos.
According to Plato, our world is but an imperfect copy of the real world of ideas impressed onto matter by the Demiurge; the universe is thus a combination of matter and perfect ideas.
In the Critias, Plato characterizes Atlantis as possessed of an ideal political system.
Gaius Plinius Secundus, called Pliny the Elder, writes the monumental Historia naturalis, the earliest truly encyclopedic work, published in 77 as a series of anthologies concerned with such scientific and technical topics as anthropology, botany, cosmography, metallurgy, psychology, pharmacology, and zoology.

The Middle East: 892–903 CE
Abbasid Consolidation, Regional Revolts, and Cultural Advances
Restoration of Abbasid Authority
In 896 CE, Abbasid Caliph al-Mu'tadid decisively crushes the long-standing Kharijite Rebellion, restoring caliphal authority across the troubled regions. However, despite this victory, the Abbasid Caliphate continues to face significant internal and external challenges.
Rise of the Qarmatians
At the close of the ninth century, Bahrain—encompassing much of eastern Arabia and surrounding islands—falls prey to internal strife exacerbated by disturbances in Abbasid Iraq. Seizing upon these disruptions, the Qarmatians, led by Abu Sa'id al-Hasan al-Jannabi, take control of Bahrain’s capital, Hajr, and the region of al-Hasa in 899 CE. Al-Jannabi establishes a utopian society, positioning al-Hasa as the capital of his revolutionary republic. The Qarmatian state thus emerges as a formidable new power in the region.
Geographical Scholarship and Persian Culture
The Persian geographer Ahmad ibn Rustah composes his significant geographical work, the Book of Precious Records, during this era. Ibn Rustah's meticulous account provides valuable firsthand insights, especially about his hometown of Isfahan, detailing its layout, defenses, and administrative divisions. His writings also encompass broader geographic descriptions, including Europe and Inner Asia, making him an indispensable source for otherwise poorly documented regions. Ibn Rustah's notable observation of a Caucasian king who pragmatically worships with Muslims, Jews, and Christians highlights the region's religious diversity and political pragmatism.
Emergence and Identity of the Kurds
The term "Kurd" appears increasingly in early Islamic sources, primarily referencing pastoral nomadic lifestyles rather than defining a distinct linguistic or ethnic group. Early Persian and Arabic texts describe "Kurds" as an amalgamation of various Iranian and Iranicized nomadic tribes, often highlighting their nomadic and pastoral traits rather than linguistic unity.
Medical Advances and Cultural Contributions
The renowned Persian physician Agha Bakr Muhammad ibn Zakariya al-Razi (also known as al-Razi, 845–930 CE), who maintains a laboratory and medical school in Baghdad, significantly advances medical knowledge. In his manual, Man la Yahduruhu Al-Tabib, al-Razi notably advocates the use of opium for anesthesia and the treatment of melancholy, reflecting both practical medical innovations and the continuing legacy of classical medical traditions.
Jewish Mysticism and Philosophical Developments
The prominent Jewish philosopher and scholar Saadia ben Joseph al-Fayyumi, known as Saadia Gaon, heads the Talmudic academy of Sura. Saadia engages in extensive theological and philosophical debates, notably confronting the Karaites over their challenges to Judaic tradition. His significant literary contributions include commentaries on mystical texts like the Sefer Yetzira (Book of Creation), foundational in the development of Jewish cosmology and mysticism. Saadia’s writings profoundly influence Jewish mystical thought, particularly regarding the sefirot, which conceptualize humanity as a microcosm of creation.
Linguistic Shifts in Iranian Languages
This period witnesses significant linguistic transitions, with the flexible word order characteristic of Middle Iranian languages gradually evolving into the more rigid word order structures of Modern Iranian languages. This shift marks an essential phase in the historical development of the Iranian linguistic tradition.
The Middle East: 904–915 CE
Fragmentation of Abbasid Authority and the Rise of Regional Powers
From 904 to 915 CE, the Abbasid Caliphate faces an accelerating decline of central authority, evident through the growing autonomy and influence of ambitious provincial governors and military commanders. The Abbasid caliphs, increasingly confined to ceremonial roles in Baghdad, see their practical power diminish significantly.
Emergence of Local Dynasties
Local and regional dynasties solidify their control throughout the empire. The Saffarids, having displaced the Tahirids in eastern Iran, consolidate their power by 873 and assert continued dominance during this period. Additionally, Mesopotamia sees the rise of various regional rulers, further fragmenting the caliphate’s once-unified territories.
Revolt and Rebellion
In Bahrain, which encompasses significant portions of eastern Arabia, the Qarmatians under Abu Sa'id al-Hasan al-Jannabi fortify their hold following their earlier capture of the capital Hajr and al-Hasa in 899 CE. Al-Jannabi continues to establish his revolutionary republic based on utopian ideals, significantly disrupting Abbasid control in the region.
Intellectual and Cultural Flourishing
Despite political fragmentation, intellectual and cultural advancements persist. The Persian geographer Ahmad ibn Rustah compiles his detailed geographic compendium, the Book of Precious Records, providing valuable first-hand descriptions of his native Isfahan and insights into regions as distant as Europe and Inner Asia.
The esteemed Persian physician Agha Bakr Muhammad ibn Zakariya al-Razi (al-Razi) continues to advance medical knowledge from his school in Baghdad, advocating opium use in anesthesia and melancholy treatment, reflecting continued innovation within Islamic medical traditions.
Religious and Linguistic Transformations
The Jewish philosopher and theologian Saadia Gaon remains active as head of the Talmudic academy of Sura, vigorously debating religious interpretations and authoring significant commentaries, notably on mystical texts such as the Sefer Yetzira. These writings greatly influence Jewish mystical thought, especially regarding the concept of the sefirot.
Linguistically, the transition from Middle Iranian languages to Modern Iranian continues, marked by a shift toward more rigid grammatical structures and syntax.
Kurdish Identity and Cultural Shifts
The identity of the "Kurds" becomes clearer in early Islamic sources, though still primarily described by their nomadic and pastoral lifestyle rather than as a distinct linguistic group. They emerge as a significant presence in the social and political dynamics of the region.
Thus, this era encapsulates both the fragmentation of Abbasid political authority and ongoing cultural and intellectual vitality across the Middle East.

Irrigation and terracing: Toltec and Mixtec systems optimized rainfall in highlands; Isthmian chiefdoms used raised beds and canal gardens in lowlands.
-
Metallurgy: lost-wax casting and alloying of gold, copper, and silver; ornaments used as tribute and ritual offerings.
-
Architecture: columned temples and walled precincts at Tula and Chichén; mounds and ballcourts in Costa Rica and Panama; open plazas for markets and ceremonies.
-
Navigation: dugout canoes on both coasts; Toltec and Itzá maritime routes connected the Yucatán with Panama and Ecuador.
-
Ceramics: polychrome pottery of Nicoya and Gran Coclé reflected cross-cultural aesthetics between Mesoamerica and the Isthmus.
Belief and Symbolism
Religion unified the region’s diversity through ancestor worship, cosmological dualities, and ballcourt ritual.
-
Toltec and Itzá theology fused the sun–war god (Quetzalcoatl–Kukulcan) with notions of cyclical creation.
-
Mixtec codices immortalized lineage founders and divine marriages as cosmic dramas.
-
Isthmian gold and stone art depicted hybrid beings—jaguar-men, crocodile–eagles—symbolizing shamanic transformation.
-
Ballcourts, present from Tula to Diquís, reenacted the balance of life and death, politics and the cosmos.
-
Ancestor burials, accompanied by gold pectorals and jade ornaments, expressed kin-based authority; stone spheres embodied harmony and world order.
Movement and Interaction Corridors
-
Overland highways: Tula to Oaxaca and Soconusco; Mixtec roads over the Sierra Madre to Pacific cacao ports.
-
Maritime routes: Chichén Itzá’s ports (Isla Cerritos) to Belize and Honduras; canoe trade from Panama to Nicaragua and onward to Mexico.
-
Isthmian portages: Chagres, Bayano, and Reventazón rivers served as proto-canal routes linking Pacific and Caribbean economies.
-
Capes of Ecuador and Darién tied the Isthmus into Andean trade, passing gold and Spondylus shells northward.
Adaptation and Resilience
-
Ecological diversity—from highland terraces to rainforest gardens—insured against climatic stress.
-
Dual-coast economies used Pacific fisheries and Caribbean trade to offset agricultural shortfalls.
-
Political plurality maintained resilience: multiple city-states and chiefdoms prevented single-point collapse.
-
Artisanal prestige economies—centered on gold, jade, and cacao—stabilized alliances through ritual and exchange rather than coercion.
Long-Term Significance
By 1107 CE, Middle America had become a continental crossroads of power and artistry:
-
Toltec Tollan and Chichén Itzá anchored the northern highlands and maritime Yucatán as twin centers of innovation and trade.
-
Mixtec and Zapotec hill states codified dynastic histories and expanded sacred architecture.
-
Costa Rica–Panama chiefdoms reached the zenith of goldworking sophistication, linking the Isthmus with both the Andes and Mesoamerica.
-
Canoe and portage routes unified the Caribbean and Pacific for the first time, prefiguring the region’s enduring role as a global transit zone.
This age defined Middle America as a land of metal, maize, and myth—where jade, gold, and cacao flowed together through networks of pilgrimage, trade, and ritual that bound the American continents into one dynamic cultural sphere.
“One cannot and must not try to erase the past merely because it does not fit the present.”
