Why Don't Valentine Hearts Look Like Real Hearts?

Love is in the air today, and images of two-lobed hearts are all over everything: candy, cards, decorations, you name it. That the heart is symbolic of love and passion isn’t surprising. Ancient Greek and Roman thinkers, including Aristotle, thought the organ was the center of all emotions. Why the heart symbol you see everywhere in February doesn’t look anything like an actual human heart, though, is a little less clear.

The symbol goes at least as far back as the 1400s, when it appeared on European playing cards to mark one of the red suits, and it may even be older than that. The shape is pretty much a mystery, though. There are a few different hypotheses to explain it, but none of them have been confirmed.

One suggested origin for the symbol is that it comes from the ancient African city-state of Cyrene, whose merchants traded in the rare, and now extinct, plant silphium. The plant was used to season food, but doubled as a contraceptive. A silphium seedpod looks like a valentine's heart, so the shape became associated with sex, and then with love.

Another possibility is that the shape is a crude representation of a pubic mound, the vulva, a pair of breasts, buttocks, or a pair of testicles. It may even have come from a poor attempt at drawing an actual heart. A lousy artist, an inaccurate description of the subject, or a malformed model all could have led to that shape.

The Catholic church explains the symbol as coming from a vision that Saint Margaret Mary Alocoque had, where the “Sacred Heart of Jesus”—associated with love and devotion by Catholics—appeared in this shape surrounded by thorns. But Alocoque didn’t have this vision until the late 1600s, well after the symbol was already documented. This makes it the unlikeliest of origin stories, but the church’s frequent use of the shape was probably a driving factor in popularizing it as a symbol of love.

Archaeologists Discover Ancient Sunken City in the Mediterranean

Early on July 21, 365 CE, an 8.5 magnitude earthquake shook the eastern Mediterranean, triggering a powerful tsunami. The Egyptian city of Alexandria was damaged, towns crumbled on the island of Crete, and the Roman port city of Neapolis, located on the coast of North Africa, was largely swallowed by the wave, according to historical records. Now, after being hidden under water for more than 16 centuries, the remains of Neapolis have been discovered by archaeologists off the coast of northeast Tunisia. This, according to the AFP, confirms accounts that the city was a casualty of the ancient natural disaster.

Following several years of exploration, researchers from the Tunisian National Heritage Institute and the University of Sassari in Italy have discovered nearly 50 acres of watery ruins near the modern-day city of Nabeul. They include streets, monuments, homes, mosaics, and around 100 tanks used to make garum, a fish-based sauce that was so popular in ancient Rome and Greece that it's been likened to ketchup. 

These containers suggest that Neapolis was likely a major producer of garum, making the salty condiment an integral part of the city's economy. "Probably the notables of Neapolis owed their fortune to garum," expedition head Mounir Fantar told the AFP.

Neapolis ("new city" in Greek) was originally founded in the 5th century BCE. While it was an important Mediterranean hub, its name doesn't appear too often in ancient writings. According to The Independent, it may because the city sided with the ancient city-state of Carthage—founded in the 9th century BCE by a seafaring people known as the Phoenicians—in the last of a series of three wars, called the Punic Wars, against Rome.

The Third Punic War stretched from 149 to 146 BCE, and led to the burning of Carthage. (It was later rebuilt as a Roman city by Julius Caesar.) Neapolis may have been punished for its wayward allegiance, which may explain why it's rarely mentioned in historical accounts.

Archaeologists Find Italy's Earliest Wine—And It's Thousands of Years Older Than We Thought

Uncork a Barolo in honor of ancient traditions: Italians have been making wine for far longer than we thought. A new analysis of storage jars found in a cave in Sicily's Monte Kronio pushes back Italy’s wine-making history by thousands of years, as CNET alerts us.

Archaeologists from the University of South Florida and several Italian institutions report in Microchemical Journal that wine making in the region could date back as far as 3000 BCE. Previously, researchers studying ancient seeds hypothesized that Italy's wine production developed sometime between 1300 BCE and 1100 BCE.

Making grapes into wine has been a part of human history going back to the Stone Age. Georgians have been drinking wine for 8000 years. Grapevines spread through the Caucasus and the Middle East before making their way to Europe.

This new discovery was possible thanks to chemical analysis of unglazed clay pots found in a Monte Kronio cave. The Copper Age pottery still bore residue from the wine. The researchers were able to identify traces of tartaric acid and sodium salt left from the wine-making process. They're still working on figuring out whether it was red or white, though, as University of South Florida researchers explained in a press statement.

In 2013, archaeologists planted a vineyard and began making wine using ancient Roman techniques to see what wine actually tasted like in the Roman Empire. Foul as that wine may have been, it seems that Roman wine was the result of an even longer wine-making tradition than we knew.
