20th century BC

falls, and Mesopotamia breaks into rival city-states as Amenemhat I refounds kingship; the first Cretan palaces rise and an Assyrian merchant network begins knitting the wider world together.

Mental Worlds: Evidence and Inference

A scribe trained in or this century inherits a library already old. The , which took shape under 's last dynasty a century earlier and continued to be reworked afterward, still frames kingship as something the gods lower from heaven city by city, and the Curse of Agade still explains imperial collapse as divine punishment for royal impiety, a moral he has just watched play out again in Ur's own fall. He can recite Ur-Nammu's law code and the hymns Shulgi commissioned to have himself worshipped as a living god, even though the dynasty that produced them no longer exists. His own king, Ishme-Dagan of Isin, has had new hymns written claiming that vanished prestige for himself, an act of political theater the scribe copies without necessarily believing.

He knows almost nothing of beyond trade goods and travelers' report, and an scribe would know just as little of him. That scribe, serving the new Twelfth Dynasty, has his own recent political literature to master: the , staged as an ancient sage's vision but written to retroactively bless Amenemhat I's seizure of the throne, and the , a posthumous voice-piece in which the murdered king warns his son to trust no one, family included. He also copies the , generations old by now, and drills the formulaic Kemyt as a child learning to write. Egyptian literature at this date is instructional and dynastic rather than narrative; the great story-cycles, Sinuhe among them, belong to the coming decades.

A merchant traveling the roads between and in central Anatolia knows a different world again, one measured in donkey caravans, tin, and textiles rather than royal hymns. The archive he will leave behind, thousands of private letters and contracts, has barely begun to accumulate; the system that generates it, an Assyrian trading colony embedded in a foreign city under local rulers' protection, is itself a recent and fragile arrangement. He would find nothing to read from , where builders have just begun raising the first palace at , a structure whose purpose, part storehouse, part shrine, part seat of authority, is legible archaeologically but left no contemporary text to explain it in its own words.

None of these figures could read the others' scripts even where correspondence existed, and no one this century has produced anything resembling epic narrative as later ages will define it. What passes for extended literary composition is hymnic, legal, or admonitory: praise of kings and gods, codes claiming to fix just prices and punishments, advice literature staged as a father's or predecessor's voice. The great flood story that will become Atrahasis and, later, part of Gilgamesh, likely already circulates in some oral or fragmentary form, but no text of it from this century survives to prove it. Rigveda's hymns are five centuries from being composed even orally; Hammurabi's stele, the Old Babylonian Gilgamesh, and the archive are all a lifetime and more away. What exists instead is a set of regional literatures, Sumerian, Akkadian, , each serving its own scribal bureaucracy, unaware how thoroughly later centuries will braid Mesopotamian and Levantine material together into shared story-cycles. For now, the furthest any single mind's reading plausibly reaches is a few hundred miles and, at best, a few centuries back.

State of the domains

Texts and Written Culture

Sumerian royal hymnody survives 's fall: Ishme-Dagan of has scribes compose hymns claiming the dead empire's prestige for his rump kingdom, while laments already circulating mourn a lost golden age. In the new Twelfth Dynasty commissions the , a fictional sage's vision retrofitted to predict Amenemhat I's own accession, and the , purporting to be the murdered king's posthumous warning to his son against trusting anyone. Scribal schools copy the , an older king's political testament, and Kemyt, a formulaic primer that will train bureaucrats for centuries to come, still being copied in school exercises seven hundred years later.

Art

's newly founded Twelfth Dynasty revives Old Kingdom sculptural and relief models at and after a century of provincial improvisation, its royal portraiture under Amenemhat I and Senusret I still idealizing rather than the careworn realism later Twelfth Dynasty kings will adopt. On the first palaces rise at , Phaistos, and Malia, organizing storage, ritual, and craft production around open central courts, the opening move of a distinct Aegean artistic tradition. Mesopotamian cylinder seals from and keep the repetition-heavy presentation scenes of the III chancery, without its former unity.

Medicine

No medical text survives from this century itself; the medical papyri that exist today are later copies, and nothing comparable has yet been found from - Mesopotamia. What can be said rests on later, retrospective evidence and general knowledge of the period: healing was folded into temple and household ritual, treating illness as a matter of divine anger, demonic attack, or bodily imbalance addressed through incantation alongside practical treatment. Egyptian and Mesopotamian physicians already draw on centuries of accumulated observation, but the earliest texts that let a reader see their methods directly belong to later centuries.

Science

Mesopotamian administration runs on a mature sexagesimal number system, dividing weights, measures, and time-reckoning into sixties and their multiples, a legacy of III bureaucratic record-keeping now inherited piecemeal by and scribes. surveyors and treasury officials use their own fraction system for grain and land accounts, the tradition that later produces the Rhind and Moscow papyri. Systematic astronomy has not yet appeared; the sky is watched for omens and calendar-keeping rather than measured. Mathematics at this date is a practical craft embedded in administration and construction, not yet a subject written about for its own sake.

Military

Chariot warfare has not yet arrived; armies fight on foot with bronze-tipped spears, axes, and simple or, in some depictions, composite bows, organized around city levies rather than professional standing forces. 's fall left no single Mesopotamian power able to dominate the others, so and contest the old imperial heartland in a slow, indecisive rivalry that will run for two more centuries. 's Twelfth Dynasty, by contrast, consolidates: Amenemhat I builds fortresses along the eastern Delta frontier and pushes control southward into Nubia, the start of a state-directed military buildup his successors will extend as far as the Second Cataract.

Technology

Bronze remains the working standard for tools and weapons across the Near East, alloyed from copper and tin routed through long-distance networks whose sources are still not fully mapped by archaeologists. Mesopotamian irrigation canals, silted and neglected during 's collapse, are being reclaimed piecemeal by and . continues large-scale stone quarrying and canal work tied to flood management. Writing itself is a technology in active use: cuneiform on clay across Mesopotamia, hieroglyphic and hieratic on papyrus and stone in Egypt, each system already centuries old and administratively indispensable.

New this century

  • Cretan Hieroglyphic and Linear A · Anonymous / Minoan palace and ritual administrators

    Minoan Crete developed two related but distinct scripts, Cretan Hieroglyphic and Linear A, to record palace and sanctuary transactions in numbers, commodities, and personal or divine names whose underlying language, or languages, still cannot be securely identified.

  • Prophecy of Neferti · attributed to the sage Neferti

    A kingdom in chaos will right itself only through a savior king whose arrival is foreordained, and the current king's rule can be read backward into that same prophecy.

  • Instruction of Amenemhat · attributed to Amenemhat I, spoken posthumously

    Trust no one, not even a brother or a friend raised up by your own hand, because betrayal comes from those closest to the throne.

  • Code of Lipit-Ishtar · Lipit-Ishtar of Isin

    A Sumerian-language code from the Isin dynasty argues that a king renews his legitimacy through divinely commanded justice, echoing the prologue formula of Ur-Nammu's earlier code and presenting law as inherited tradition rather than personal invention.
