Died of Forgotten

The gate of the gods — Hammurabi's law and Nebuchadnezzar's blue-glazed Ishtar Gate and city walls, the greatest city on earth. Cyrus walked in without a fight in 539 BCE, and the centre of the world slowly emptied into dust and Scripture.

The thunder-king of the Rigveda who split the serpent Vritra with his vajra to free the waters, the god the early Indo-Aryans begged for victory — dethroned within his own living religion as Vishnu and Shiva rose above him. He still holds a minor seat in the heavens; the supremacy is gone.

The most prized metal in the Roman world — worth more than gold. It produced a dark, lustrous patina unique in antiquity. After Rome sacked Corinth in 146 BCE, Romans wrote about it as something they could no longer make. Not a single confirmed example survives.

A name half-god, half-rite, demonized by scripture for the child sacrifices of the Valley of Hinnom, until King Josiah's reforms suppressed the rite.

Recovered in 1901 from a Roman shipwreck off the Greek island of Antikythera, this geared bronze computer from roughly 100 BCE predicted eclipses and tracked the planets. Nothing of comparable mechanical complexity appeared anywhere on Earth for another 1,400 years.

The incense burned twice daily in the Jerusalem Temple. Its eleven ingredients were known; one — the one that made the smoke rise in a perfectly straight column — was a secret held by a single family, the Avtinas. They died with the Temple in 70 CE.

The most valuable crop of the ancient world — spice, medicine, and the economic engine of Cyrene — could not be cultivated, only wild-harvested. So it was harvested to extinction — Pliny the Elder records that the last stalk was sent to the Emperor Nero as a curiosity.

The violent maiden who waded thigh-deep in the blood of warriors to avenge her brother Baal.

The remote sky-father worshipped at Uruk, at the very top of heaven, so far above that the prayers eventually stopped reaching him at all.

Grain-god of Mesopotamia turned Philistine patron, whose idol toppled before the Ark of the Covenant and never rose again.

The Mesopotamian shepherd-god, consort of Inanna, who died each year so the harvest could live — mourned for millennia, his name wept in the biblical book of Ezekiel, and now mourned by no one.

Enki of Eridu — Ea to the Akkadians — the cunning god of fresh water and wisdom who saved humankind from the flood, now drowned in the silence of his own waters.

Lord of wind and command, keeper of the Tablet of Destinies who from his temple at Nippur once decreed the fates of gods and men, his word now scattered like the air he ruled.

Mesopotamian dread queen of the land of no return, who kept the dead — and even her sister Ishtar — behind seven gates, and now keeps only silence.

The Sumerian queen of love and war, identified with the planet Venus, who descended into the underworld and returned, yet found no return from the silence that swallowed her temples.

The slayer of the chaos-dragon Tiamat who rose, through the Enuma Elish, to king of all gods in Babylon, now silent under the desert that buried his city.

Death itself, with a lip to earth and a lip to sky, who swallowed the storm-god Baal and was ground to dust by the goddess Anat for it.

Divine scribe of Borsippa who held the stylus that recorded every fate on the Tablet of Destinies, his clay tablets now read by no worshipper.

God of plague, war and the scorching noon sun, whose temple stood at Kutha; he marched into Ereshkigal's underworld to rule it, and there fell quiet.

The Sumerian mountain mother who shaped humankind from clay alongside Enki, her nurturing name long since gone barren in memory.

The all-seeing Mesopotamian sun god who handed King Hammurabi his law code, now blind to the worshippers who no longer look up.

The primordial salt-sea goddess slain by Marduk, her body split to become the sky and earth, now as voiceless as the chaos she once was.

Tyre and Carthage's king-god who died and rose each spring, later mistaken for Heracles and then forgotten entirely.

Carthage's chief goddess and consort of Baal Hammon, her sign still scratched on Punic stelae long after Rome razed her city in 146 BCE.

Phoenician goddess of love and war whose evening star — the planet Venus — outshone empires; condemned in Hebrew scripture as Ashtoreth, until the cult of Mary inherited her light.

Baal Hadad, the storm-rider who slew Yam the sea and Mot the death-god, then watched his own worshippers turn to scripture's mockery.

Sidon's healer-god, the Phoenician Asclepius, who castrated himself to flee a goddess and was reborn as her divine warmth.

King of the Gods of imperial Egypt and master of Karnak, the largest religious building ever raised. His oracle at Siwa hailed Alexander the Great as a god's son; he outranked pharaohs, and ended with the old religion.

The Egyptian sun himself — sailed nightly through the underworld and rose again each dawn for three thousand years. When the edict of Theodosius I closed the pagan temples in 391 CE, the sun kept rising, and no one prayed to it again.

An Anatolian mother goddess, the Magna Mater, shipped to Rome as a black stone in 204 BCE and installed as an official state cult. Her public worship was ended by the anti-pagan edicts of Theodosius I in 391–392 CE.

Once one of Rome's top three gods, ranked beside Jupiter and Mars in the Archaic Triad with his own flamen and the Quirinalia festival, and later identified with the deified Romulus. By the late Republic he had faded to an antiquarian footnote, his cult withered while Rome was still pagan.

Greek goddess of love, beauty and desire, worshipped from Cyprus to Rome and claimed by Caesar's family as their ancestress. Her sanctuary at Paphos held unbroken cult until 391 CE, when Theodosius I outlawed pagan worship and the temples closed.

The oracle-god of Delphi, whose Pythia was consulted by the whole Greek world before war and colony. When Theodosius I turned Rome Christian his sanctuary was closed and his oracle fell silent in 393 CE.

Patron goddess of Athens, wisdom and war in one figure, the Parthenon raised in her name on the Acropolis. When Rome turned Christian her temples were closed and her worship silenced.

The sea-god every Greek sailor feared, brother of Zeus and Hades, lord of storms, earthquakes and horses. His temples emptied when Rome turned Christian and the sacrifices stopped.

King of the Greek gods, thunder in his hand, the Olympic Games sworn in his name at Olympia from 776 BCE and Pheidias's statue of him counted among the Seven Wonders. The emperor Theodosius I banned his games in 393 and his temple was burned; the sky-father fell silent.

The many-skilled god of the Gauls and the Irish — likely the deity Caesar called the Gauls' Mercury, with cities from Lyon to Carlisle carrying his name. In Irish myth he slew the Fomorian Balor with a sling; today he survives mostly as a date on the calendar: the festival of Lughnasadh and Lúnasa, the Irish month of August.

The jackal god who weighed the hearts of the dead against the feather of Maat and oversaw the embalming of Egypt. He died with the religion that needed him, when the last temples of the old gods were shut.

The falcon sky-god whose living image every pharaoh claimed to be. When Egypt's temples were shut under Christian Rome, he was silenced along with the rest of his gods.

Worshipped from the Nile to Roman Britain for more than two thousand years. The silence began c. 537 CE, when Justinian shut her last temple at Philae.

Egypt's god of the dead and of resurrection, who promised eternal life to anyone who knew his name. His own cult could not be raised again: when Justinian closed Philae's temple in 537, the last god of old Egypt went into the dark he ruled.

The Slavs' thunder-god, sworn on by warriors and raised over Kyiv. When Vladimir chose Christ in 988, they dragged Perun's silver-headed idol through the streets and threw it in the Dnieper, and the people wept on the banks.

The Allfather — god of war, wisdom and the hanged, who gave an eye at Mímir's well for knowledge and hung nine nights on the world-tree Yggdrasil. Christ's kings tore down his temple at Uppsala; now he survives mainly as Wednesday, the day that still carries his name.

The thunder god of the Vikings, god of the common people, whose hammer Mjölnir was the most-worn amulet and whose name was the most-given name of the age. Christianity switched him off.

An eleven-metre water-powered clock tower built in 1088, with an escapement six centuries ahead of Europe. When the Jurchen sacked Kaifeng in the Jingkang Incident of 1127 they carted it off, could not rebuild it, and the technology was lost in China for nearly a thousand years.

Sold at twice its weight in gold, it was the most valuable agricultural product of the ancient world. Pliny the Elder records that Jewish defenders destroyed the orchards rather than let Rome take them. In 2024 the Hebrew University grew a tree from a thousand-year-old seed — but the tree had none of the famous scent.

A weapon that burned on water and could not be doused, brought to Constantinople by the engineer Callinicus around 672 CE. The Byzantine Empire guarded its recipe so carefully that when the city fell to the Fourth Crusade in 1204, the secret fell with it — and it has never been reproduced.

Three bowls survive. All are National Treasures of Japan. Decades of attempts by Japanese and Chinese ceramicists have produced approximations of the iridescent oil-spot effect — not the original. The Song Dynasty potters at the Jian kilns in Fujian never wrote down how they did it.

In 1206 the engineer Ismail al-Jazari described programmable water-clock automata — an elephant clock, a hand-washing robot, a drummer whose rhythm you could change by moving pegs. Europe's mechanical clockwork swept the tradition aside, and not one of his machines survives.

Chief thunder god of the Balts, the last pagans in Europe. His sacred oaks and the perpetual fire tended in his honour were felled and put out when Grand Duke Jogaila converted Lithuania, the last pagan state on the continent, in 1387.

The Old French of the Jews of medieval France, written in Hebrew script — the vernacular the great commentator Rashi used to gloss hard words in the la'azim of his commentaries. The expulsions of French Jewry broke its communities; after the final one in 1394, the language did not survive the scattering.

The Slavic language of the Jews of medieval Bohemia — essentially Old Czech written in Hebrew letters, even stamped on coins. It died when Yiddish-speaking Jews moved east and the local community switched tongues, leaving only glosses — dozens marked 'in the language of Canaan' in the rabbinic compendium Or Zarua — and a handful of inscribed coins.

The serpent-skirted Aztec mother of the gods, killed by her own children, who conceived the sun-god Huitzilopochtli from a ball of feathers.

The hummingbird of the south, Aztec god of war born armed to slay his sister, who demanded human sacrifice to keep the sun alive.

Aztec lord of Mictlan, the lowest underworld — a blood-spattered skeleton who guarded the bones Quetzalcoatl stole to remake mankind.

The feathered serpent who gave humanity maize and his own blood, mistaken at the end for the Spanish conqueror whose seizure of Tenochtitlan in 1521 ended his cult.

The smoking mirror who saw every heart, lost a foot to the earth-monster Cipactli, and watched empires rise to fall at his whim.

The goggle-eyed Aztec rain-bringer whose paradise welcomed the drowned, fed by the tears of sacrificed children — until the Spanish conquest of Tenochtitlan in 1521 ended his cult.

The Aztec flayed lord who wore the skin of the sacrificed as new spring growth wears the dead husk of seed.

The golden sun whose son ruled as Inca, his Coricancha temple in Cusco stripped of its gold plates to ransom the captive emperor Atahualpa.

The creator who rose from Lake Titicaca to make the sun, moon, and men, then walked west across the sea and never returned.

The long-nosed Maya god of rain who split the clouds with his lightning-axe, fed by the bodies cast into cenotes, the sacred sinkholes.

The aged Maya creator known to scholars as God D, who taught writing, the calendar, and cacao, then was erased by the script of his Spanish conquerors.

The jaguar-clawed Maya moon goddess of childbirth and weaving, whose shrine on the island of Cozumel drew pilgrims across the sea.

The Maya feathered serpent god of Chichen Itza, cognate with Quetzalcoatl, who slithers down his pyramid El Castillo in light each equinox while its 365 steps still count the solar year.

The Inca knotted-cord recording system. Spain ordered it destroyed in 1583, and within a generation the trained khipukamayuq readers were dead. About 900 khipu survive in museums worldwide. The numeric ones are partially decoded. The narrative ones — the histories, the stories — are completely mute. There is no Rosetta Stone.

The amanteca built shimmering mosaics from quetzal and cotinga feathers for the Mexica court. The 1521 conquest broke the guild, the tribute, and the supply of birds. The technique died with the last masters, and the few surviving pieces have never been truly matched.

The universal antidote attributed to Mithridates VI of Pontus: a compound of sixty-four ingredients, including viper flesh and opium, claimed to neutralise all poisons. Manufactured ceremonially for over 1,800 years until the French Académie de médecine declared it worthless in 1745. The ingredient list survives; the preparation knowledge — and whether it ever actually worked — died with it.

A Basque company held a royal monopoly on Venezuela's cacao for half a century, ran its own coast guard against smugglers, and fixed prices low enough that in 1749 the planter Juan Francisco de León marched on Caracas to demand its expulsion. Bourbon free-trade reform dissolved it into the Royal Company of the Philippines, and it was forgotten.

Hunter-gatherers of Newfoundland who painted their bodies, canoes and tools with red ochre — one suggested origin of the term 'Red Indians' — gone as a distinct people by June 1829, when Shanawdithit died of tuberculosis in St. John's.

Easter Island carved a script no other Pacific culture had. Then the Peruvian slave raids of 1862–63 and the smallpox that followed killed the people who could read it within a few years. Twenty-six inscribed objects survive, and after 150 years of attempts, no one can decipher a line of them.

Spun from the golden filaments of the largest clam in the Mediterranean, sea silk was finer than cashmere and lighter than air. The craft is down to perhaps one practitioner, Chiara Vigo in Sardinia. The clam that produces the fibre, Pinna nobilis, lost an estimated 99% of its population to a haplosporidian parasite in 2016–2020.

Five Rocketdyne F-1 engines, each 1.5 million pounds of thrust, lifted the Saturn V and carried Apollo to the Moon. The blueprints survived; the ability to build it did not. When NASA examined the old F-1 engines in 2013 for possible revival, the engineers found that the original drawings were dimensionally inaccurate — the actual engines differed from the plans because workers had modified them by hand and never updated the documentation.

Its Magic Cap devices — the Sony Magic Link and Motorola Envoy — were the smartphone in 1994, shipped to almost nobody, before the company dissolved in 2002 and its alumni went on to build the iPhone and Android.

When Marie Smith Jones died in 2008, a language spoken for centuries on Alaska's Copper River delta went silent inside a single human being.

A Great Andamanese tongue of the Andaman Islands, perhaps tens of thousands of years old. Its last speaker, Boa Sr, spent her final years unable to speak it with anyone.

The southernmost language on Earth, from the tip of Tierra del Fuego. It gave the world 'mamihlapinatapai' and, in 2022, lost Cristina Calderón, its last fluent speaker.
