c. 550 BCENabonidus digs for older kings
Babylon's last king excavated ruined temple foundations at Ur and Sippar, hunting the foundation deposits of rulers like Naram-Sin, roughly 1,700 years his senior, and recorded what he found. His daughter En-nigaldi-Nanna kept a labeled collection of antiquities at Ur that Leonard Woolley, digging in 1925, described as the earliest known museum.
1748Pompeii excavations begin
Under Charles of Bourbon, king of Naples, workmen began digging into Pompeii, ten years after tunneling started at neighboring Herculaneum. The work was closer to royal treasure-mining than science — statues and frescoes went straight to the palace — but two buried Roman cities made the deep past a European obsession and, eventually, a laboratory for method.
1822Champollion deciphers hieroglyphs
Using the Rosetta Stone's parallel Greek, demotic and hieroglyphic texts — found by French soldiers at Rashid in 1799 — Jean-François Champollion announced his decipherment of ancient Egyptian in his Lettre à M. Dacier. Egypt's own written history opened, and excavation in the Nile valley acquired a reading public across Europe.
1836Thomsen publishes the Three-Age System
Christian Jürgensen Thomsen, curator of the Danish national collection in Copenhagen, published his guidebook sorting prehistoric artifacts into successive ages of stone, bronze and iron. The Three-Age System gave prehistory its first workable chronology — built by ordering objects and their find contexts, not by trusting ancient texts.
1873Schliemann's treasure at Troy
Digging a massive trench through the mound of Hisarlik in Ottoman Turkey, Heinrich Schliemann unearthed a hoard of gold and silver he named "Priam's Treasure" and declared Homer's Troy found. He was roughly right about the place and wrong about the layer — his trench destroyed much of the city of Homer's era — and his methods became the cautionary tale the next generation defined itself against.
1922Carter opens Tutankhamun's tomb
On 26 November 1922, in the Valley of the Kings, Howard Carter peered by candlelight through a hole into the first intact royal tomb found in Egypt and answered Lord Carnarvon's "Can you see anything?" with "Yes, wonderful things." The ten-year clearance that followed — some 5,400 catalogued objects — made archaeology front-page news worldwide.
1949Libby's radiocarbon revolution
Chemist Willard Libby and colleagues at the University of Chicago published the first radiocarbon dates, checking the method against objects of known age from Egyptian tombs. For the first time, organic finds could be dated without any written record; chronologies worldwide were rebuilt, and Libby received the Nobel Prize in Chemistry in 1960.
1974Farmers find the Terracotta Army
In March 1974, farmers digging a well near Xi'an struck fragments of life-sized clay soldiers; local archaeologist Zhao Kangmin recognized and began restoring them. Excavations revealed thousands of individualized warriors guarding the tomb of Qin Shi Huang, China's first emperor — the tomb mound itself deliberately left unopened, a landmark of restraint as much as discovery.
2010The Neanderthal genome is sequenced
A team led by Svante Pääbo at the Max Planck Institute in Leipzig published a draft Neanderthal genome from 40,000-year-old bones, showing that most living humans carry Neanderthal ancestry. Ancient DNA turned bones and sediments into archives of migration and kinship, and Pääbo received the 2022 Nobel Prize for it.
2018LiDAR strips the jungle from the Maya
The PACUNAM LiDAR survey, flying laser scanners over northern Guatemala, revealed more than 60,000 previously unknown Maya structures — houses, causeways, fortifications — beneath the forest canopy. Airborne and satellite sensing moved discovery from the machete to the desktop, forcing archaeologists to rethink how many people the ancient Maya lowlands held.
