The ancient Egyptians built prototypes of the modern Suez Canal

The idea to facilitate trade between the Mediterranean Sea and the Red Sea and connect the Eurasian continent was apparent even to pharaohs in the second millennium BCE. Though no physical traces remain, contemporary accounts attest to early, shorter versions of the canal, including from Herodotus.

Why only one of the seven wonders of the ancient world still exists

Greek writers recorded lists of great structures that were later codified by Renaissance writers. The definitive list includes the Colossus of Rhodes, the Giza Pyramid (the only existing one today), the Hanging Gardens of Babylon, the Temple of Artemis at Ephesus, the Statue of Zeus at Olympia, the Mausoleum at Halicarnassus, and the Lighthouse of Alexandria.

The story of Hypatia, a leading Roman scholar murdered by monks

Hypatia of Alexandria was a secular philosopher in Egypt who headed a university, improved scientific instruments, penned textbooks, and advised the city's leaders. As a Neoplatonist, she approached numbers as a sacred language. Religious fervor and her visible advisory role led to her brutal dismemberment by rogue monks.

Why are ancient ruins underground?

When cities fall into disrepair, it's often easier to flatten what you can and build on top. This is why modern archaeologists frequently discover ruins underground, revealing generational layers of cities rebuilt over time. This video explores major examples of this principle, from ancient Troy to even modern Seattle.

The Maya built their cities with advanced engineering

Maya cities featured pyramids, palaces, causeways, ball courts, and water-management systems that were engineered to support large populations—often tens of thousands—without the use of metal tools, draft animals, or wheeled transport.

What did democracy really mean in Athens?

Ancient Athens chose the vast majority of its public servants by lottery, a process of random selection known as sortition. Roughly 30,000 people were eligible for the lottery to serve as jurors, magistrates, and more. Monthly assemblies called the "ekklesia" occurred where anyone could attend and speak, but 500 governing council members called the "Boule" set the agenda.

Ancient Greek gymnasium: where philosophy met fitness

In ancient Greece, gymnasiums were not just places of physical training, but centers of intellectual life. This article explores the ways in which exercise, philosophy, and education were deeply intertwined, reflecting a cultural belief that physical fitness was essential for mental development.

Watch the history of human migration that led to civilizations

Starting in Africa where they hunted with spears and fires, humans would gradually move out of the continent over thousands of years as they navigated crossing deserts, rivers, uneven terrain, and shifting climates. Development of technology, language, farming, and other societal structures helped build up the first civilizations.

The aqueducts and cisterns of Constantinople

The system of aqueducts that supplied Byzantine Constantinople with water had more than 500 kilometers of channels. These channels fed hundreds of cisterns. The largest were open pools (one, now drained, houses an entire modern shopping center); but the most impressive were vast covered chambers like the Basilica Cistern, still a highlight of any visit to Istanbul.

Critics of Alexander the Great see him as power-hungry and ruthless

Arguments against his greatness include that he likely murdered his father for the throne, poorly led his territories, and only conquered one empire despite touting greater feats. Proponents argue that he was a skilled military leader and helped usher in the Hellenistic Age, where Greek cultural influence spread across Europe and Asia.

Ancient Greek astronomer Hipparchus created accurate maps of the night sky way ahead of his time, with coordinates sometimes within a single degree of modern values.

Paris and Boston were redesigned partly to combat cholera's spread

Georges-Eugène "Baron" Haussmann, who oversaw Paris's redesign in the 1800s, replaced many of the city's narrow streets with wide boulevards. This was done at least in part to bring more air and light into the city to help control cholera. Architect Arthur Gilman redeveloped Boston's Back Bay to similarly combat cholera, among other reasons.

When Marcus Aurelius created endowed philosophy chairs in Athens

The Roman Emperor Marcus Aurelius is known as one of the most famous Stoic writers or thinkers, penning his classic opus ‘Meditations.’ In 176 CE, he endowed four philosophy chairs in Athens: one for Stoicism, and one for three of Stoicism’s rival schools: Aristotelianism, Platonism, and Epicureanism.

How the ancients calculated Earth's size correctly

Watch this seven-minute video to hear Carl Sagan explain how ancient Greek polymath Eratosthenes correctly calculated the size of the Earth in the third century BCE. At some point, Eratosthenes noticed a discrepancy in the length of shadows cast in different cities during the summer solstice. This observation grew into a simple experiment that enabled Eratosthenes, the head librarian at the Library of Alexandria, to calculate the Earth's size precisely.

Earth's circumference was estimated over 2,000 years ago using geometry and shadows

By measuring the angle of the shadow cast in Syene when no shadow was cast in Alexandria, Eratosthenes used the distance between the two cities and trigonometry to estimate the Earth's circumference to within a few percentage points of the actual value.
