The architectural orders: not aesthetics, but grammar
Doric, Ionic, Corinthian. They are not three decorative styles — they are three proportional systems, three different answers to the same structural problem.
The Pantheon: the sphere no one sees
The dome has exactly the same diameter as the total height of the interior. 43.44 meters in every direction.
The Roman arch: not a shape, a revolution
With a wall, you can span a space as wide as the thickness of a stone. With an arch, you can span a space as wide as you want. It's the difference between a hut and an empire.
The Colosseum: the spectacle machine
50,000 spectators, 80 entrances, evacuation in 3 minutes. It's not an amphitheater: it's a logistics system with an amphitheater on top.
The Roman Forum: when the square was the world
It wasn't designed: it grew for 900 years. The Roman Forum is the sediment of a civilization, not the result of a plan.
The Acropolis: the hill as manifesto
The Parthenon has been a Greek temple, a Christian church, an Ottoman mosque, a gunpowder store. The 1687 explosion half-destroyed it. It's still there.
The Greek temple: the body as measure
The Greek temple is not a building you enter — it is a building you walk around. The worshipper stood outside, facing the statue of the god.
The Agora: The Square as Democracy
The agora of Athens: the stoa as an architectural element, the square as a place of democratic practice, and how the Greek agora became the Roman forum.
The Roman Domus: A World in Miniature
The Roman domus through Pompeii's House of the Faun: atrium, tablinum and peristyle, fresco as architecture, the four Pompeian styles and the insula.
The Roman insula: the ancient condominium
How the Roman insula worked: multi-storey rented housing, fire risk and wooden stairs, the preserved insulae of Ostia, and why the type still shapes cities.
The pyramid: geometry and eternity
2560 BC. Pharaoh Khufu orders the construction of the Great Pyramid at Giza.
The Greek theater: the geometry of sound
How the Greek theatre works: the acoustics of Epidaurus (14,000 seats, a coin heard from the top row), the theatre as a civic institution, and its legacy.
The Egyptian temple: the cosmological machine
Karnak, 1550 BCE. The high priest of Amun walks the avenue of sphinxes, passes between the two entrance pylons 40 meters high, crosses the courtyard…
The Roman baths: the engineering of wellbeing
212 CE. Emperor Caracalla inaugurates in Rome a bath complex that can accommodate 1,600 people simultaneously across 13 hectares.
The ziggurat: the artificial mountain
Ur, around 2100 BCE. Ur-Nammu, king of the Third Dynasty of Ur, orders the construction of a terraced structure rising from the alluvial plain of…
Frequently asked questions
What's the difference between the Doric, Ionic and Corinthian orders?
They're three proportional systems, not just three decorative styles. The Doric, the oldest, has no base under the columns and an essential capital — echinus and abacus — with no ornament: stocky proportions, an effect of solidity. The Ionic has a base, a slimmer shaft (height-to-diameter ratio around 1:8-1:9 versus the Doric's 1:6) and a capital with spiral volutes. The Corinthian, the latest and most ornate, has an acanthus-leaf capital. Fluting, capital, entablature: every part has a structural function before a decorative one.
How did the Romans build the Pantheon's dome without steel reinforcement?
By progressively lightening the concrete (opus caementicium) from the base upward, varying the density of the aggregate, and hollowing out the interior surface with coffers, which remove even more weight. The result — a 43.44-metre diameter — remains the largest unreinforced concrete dome from the ancient world: wider than St. Peter's (41.47 m), built fourteen centuries later.
How many spectators fit inside the Colosseum?
Between 50,000 and 80,000, depending on the estimate. The building measures 188×156 metres on an oval plan, stands 50 metres tall across four levels, and has 80 ground-floor entrance arches: a routing system designed to move a huge crowd in and out without bottlenecks.
What is a peripteral Greek temple, and how do you "read" it?
A temple surrounded on all sides by a colonnade. Unlike a church, it wasn't meant to be entered by worshippers: the god's statue stood inside the cella, worshippers stayed outside, and the building was experienced by walking around it, not by going in.
