A fresco from ancient Pompeii featured an 'ancestor of modern pizza'

A team of archaeologists discovered a fresco from 79 CE featuring what appears to be a proto-pizza: a pita topped with fruit, spices, and other toppings. One archaeologist in the PBS documentary below calls it an "ancestor of modern pizza in the sense that it's a very simple, poor kind of food."

A look at what was on the menu for ancient Romans

"Delicious Italy" is a website exploring the food culture of various Italian cities and regions, and in this article, the editors explore what is known about the diet of ancient Romans. Olives (and their oil) were a key daily essential, alongside grains like barley, millet, and spelt flour. Where meat was found it was most often ox, pork, deer, lamb, and even pigeons. Middle Eastern fruits like cherries and peaches could last long enough to travel to Roman cities around the Mediterranean, and candy-friendly dates were sourced from Africa. Explore this and much more at Delicious Italy.

Fascinating evolution of the oven

From ancient wood-fired ovens in Rome and Egypt to modern microwaves, the oven’s evolution has shaped how we cook. Early ovens focused on heat retention, but breakthroughs like the gas stove in 1834, and the electric stove in 1892, brought precision. Then, in 1967, the microwave redefined convenience.

Bake bread like a Roman, and honor Ceres, the goddess of wheat

Grains made up about 70% of the Roman diet, and the word "cereal" stems from the goddess Ceres—the Roman equivalent of Greece's Demeter—to whom they prayed for good harvests. Cato the Elder, a famous statesman, left behind a simple home recipe for a Roman loaf.

Cookies were originally used as low-stakes ways to test the temperature of an oven

In 7th century Persia, bakers used small mounds of dough to test the heat in ovens before baking larger cakes. Afterward, they'd add honey, nuts, and other items to the small mounds, creating early cookies.

When did people start making and using glass?

This article details the search for the ancient origins of glass, a now-common item through which archaeologists can spot histories of trade and innovation. Bronze Age glass was made from crushed quartz instead of sand, and artisans could color glass with materials such as cobalt. These trace metallic add-ons have given scientists a vital clue into the origins of glass, which is currently debated as either Egypt or the Near East.

Billion-year-old Arctic fossils suggest Earth had fungi far earlier than previously thought

Named Ourasphaira giraldae, this new species of fungus, reported in 2019, was found in the Grassy Bay Formation in the Canadian Arctic. It pushed the fossil record of fungi back by about half a billion years since the oldest previously recognized fungi fossils came from the Rhynie chert, a Scottish site that dates back roughly 400 million years. This fungal discovery also suggests that fungi may have occurred on land much earlier than plants, raising questions about what ancient fungi used for nourishment.

The invention of cheese likely came from a fruit fly landing in a pail of fermenting milk

The chance encounter around 5,500 years ago laid the groundwork for cultured milk products like yogurt and cheese. Over time, microbes evolved in tandem with goats, sheep, and wheat to give us the wide variety of cheeses that we enjoy today.

A timeline of human fossil discoveries

A key part of writing a coherent story about our origins is finding and identifying the remains of our ancestors and understanding their significance. Scientists will not always agree on identifications and opinions will change as new find are made and new ways of studying them are developed.

Ancient Greece originated roughly 4,000 years ago around the Aegean Sea

From architectural feats to the Western alphabet, ancient Greece has helped shape modern life. Over centuries, the eastern Mediterranean culture grew as far as India, Egypt, and Spain. Its cultural influence has long since spread beyond any physical boundaries.

The underground cities of the Byzantine Empire

This TED-Ed video explores the mysterious cave cities of Cappadocia. Although their oldest sections may go back to the Bronze Age, most of these subterranean complexes were excavated during the Byzantine period, when the locals went underground to take shelter from Arab raiders. Monasteries were also cut into pinnacles of the local tufa, and decorated with frescoes that have often survived to the present.

Food allergies were first documented more than 4,000 years ago

Although food allergies are on the rise in modern times, they have been documented in written records for thousands of years. More than 3,000 years ago, Chinese emperors advised patients to avoid certain foods, and Hippocrates noted in his work that food could cause serious harm to certain individuals, and even lead to death.

The 'definitive' history of magic mushrooms

Where did magic mushrooms come from, and how did they get their magical reputation? This article explains the history of the psychedelic fungi from pre-history to now. The earliest concrete evidence of psychedelic mushroom use is 12,000-year-old murals in Northern Australia that portray mushroom iconography. Considering how many species seek out and consume psychoactive substances, such as Siberian reindeer, it's possible human use of these psychedelic mushrooms may predate these murals.

The ancient uses of asphalt

Asphalt is derived from bitumen, a naturally occurring byproduct of decomposed organic materials. As one of the thickest forms of petroleum, the substance has been in use by humans and their ancestors for at least 40,000 years for various purposes, including as a sealant, an adhesive, decoration, and more. Learn more about this ancient material here.

The claims that Jesus was buried in the Shroud of Turin, preserved since 1578

The 14-foot linen cloth bears a faint image of a crucified man and is the most scientifically studied relic in history. The core dispute hasn't moved much: 1988 radiocarbon dating placed it in the 13th-14th century, while defenders argue the sample was contaminated by medieval repairs. No one disputes that scientists can't explain how the image was formed, which acts like a photographic negative and has no trace of paint or dye.
