Rare orichalcum metal said to be from the legendary Atlantis recovered from 2,600-year-old shipwreck

A team of marine archaeologists have discovered several dozen ingots scattered across the sandy sea floor near a 2,600-year-old shipwreck off the coast of Sicily. The ingots were made from orichalcum, a rare cast metal which ancient Greek philosopher Plato wrote was from the legendary city of Atlantis. 

According to Discovery News , a total of 39 ingots (metal cast into rectangular blocks) were found close to shipwreck that was discovered in 1988 lying in shallow waters about 300 meters (1,000ft) off the coast of Gela in Sicily.

Sebastiano Tusa, Sicily’s superintendent of the Sea Office, told Discovery News that the precious ingots were probably being brought to Sicily from Greece or Asia Minor.

Tusa said that the discovery of orichalcum ingots, long considered a mysterious metal, is  significant as “nothing similar has ever been found.” He added, "We knew orichalcum from ancient texts and a few ornamental objects.”

The name orichalucum derives from the Greek word oreikhalkos, meaning literally "mountain copper" or "copper mountain". According to Plato’s 5 th century BC Critias dialogue, orichalucum was considered second only to gold in value, and was found and mined in many parts of the legendary Atlantis in ancient times

Plato wrote that , the three outer walls of the Temple to Poseidon and Cleito on Atlantis were clad respectively with brass, tin, and the third, which encompassed the whole citadel, "flashed with the red light of orichalcum". The interior walls, pillars and floors of the temple were completely covered in orichalcum, and the roof was variegated with gold, silver, and orichalcum. In the center of the temple stood a pillar of orichalcum, on which the laws of Poseidon and records of the first son princes of Poseidon were inscribed. (Crit. 116–119)

For centuries, experts have hotly debated the metal’s composition and origin. According to the ancient Greeks, orichalcum was invented by Cadmus, a Greek-Phoenician mythological character.  Cadmus was the founder and first king of Thebes, the acropolis of which was originally named Cadmeia in his honor.

Orichalcum has variously been held to be a gold-copper alloy, a copper-tin, or copper-zinc brass, or a metal no longer known. However, in Vergil's Aeneid it was mentioned that the breastplate of Turnus was "stiff with gold and white orachalc" and it has been theorized that it is an alloy of gold and silver, though it is not known for certain what orichalcum was.

Orichalcum is also mentioned in the ‘Antiquities of the Jews’ (1 st century AD) - Book VIII, sect. 88 by Josephus, who stated that the vessels in the Temple of Solomon were made of orichalcum (or a bronze that was like gold in beauty).

Today, some scholars suggest that orichalcum is a brass-like alloy, which was made in antiquity the process of cementation, which was achieved through the reaction of zinc ore, charcoal and copper metal in a crucible.

The latest discovery of the orichalcum ingots that had laid for nearly three millennia on the sea floor may finally unravel the mystery of the origin and composition of this enigmatic metal.

Modern science is so lacking in what comprised the human past, it would be fair to say, today humanity is just emerging from another dark age. There were literally scores of elements the periodical table is lacking. First of all, the study of alchemical sciences has become so diluted, it is now considered mostly a myth. Alchemy today is believe to have been just a quest for immortality and method for changing lead to gold, but in reality, it was much, much more. True alchemy is now a lost science that involved not only forgotten energies and elements, it also involved magnetics, (both attractive and REPULSIVE) characteristics of elements long forgotten. Not only has pure orichalcum evaded modern fabrication, it will remain so because modern science is ignorant of what is necessary for, or how to produce it

There is bauxite in Greece, and the "Aiud Aluminum Wedge" artifact is very interesting. I think the orichalcum is an aluminum ore. It was lightweight, malleable and a good foil as weaponry combined with heavier gold.

It seems a bit presumptuous that they would call these ingots "orichalcum" if there is still some uncertainty as to what the substance was in reality. Even the etymology of the word is in question. It sounds plausible, but we have yet to find a way to verify the meaning of "mountain copper."

Why call it "orichalcum" if it is merely copper or a copper alloy? Was the word "orichalcum" imprinted on them? Or was the writer letting their imagination get the best of them?

If the shipwreck is only 2,600 years old, that would mean 600 BC, and far from the time of Atlantis -- 9600 BC. Too many researchers waffle over Plato's details. If we stay true to what he wrote and understand what might easily have been artistic license, then we have a better chance of solving the mystery. Looking at the details of scientific discovery, we now know that 3 items of evidence all point to a big event occurring 9600 BC. Each of these is from a different scientific discipline. Plato got a lot right about Atlantis without knowing the science we know today.

Certainly copper is the only metal with a reddish hue in its natural form, but if orichalcum were an unknown alloy, we might never know the truth of it.

But what if orichalcum were an alloy of copper and uranium? Being relatively new material from the mantle of Earth, the soil of Atlantis (if it existed) would likely have been rich with minerals, just as Plato said it was. If you look up the properties of copper and uranium, you find that their melting points are almost exactly the same!

And if the Atlanteans did indeed have an advanced technology -- the stuff of myth and legend -- then perhaps the idea that dragon ships had scales that were immensely tough could come from the addition of uranium -- one of the densest and toughest metals known. The fact that changing the ratio of metals can make a copper alloy more gold colored adds credence to this notion that orichalcum was the stuff of dragon scales. The dragons of the Egyptian merchant prince, of Cadmus and of Medea were all gold in color.

It would be nice if the author acknowledged her sources!

This nonsense again? See "Orchalchum and Related Alloys: Origin, composition and Manufacture with special Reference to the Coinage of the Roman Empire" by Earle R. Caley, The American Numismatic Society, 1964 (Monograph #151)

Also, you headline strongly implies that the ship and cargo are from Atlantis. Way to encourage the nut jobs, guys.

During the Early Woodland Period (1000—200 BC), the Adena people constructed extensive burial mounds and earthworks throughout the Ohio Valley in Ohio, Indiana, Pennsylvania, Kentucky, and West Virginia. Many of the skeletal remains found in these mounds by early antiquarians and 20th-Century archaeologists were of powerfully-built individuals reaching between 6.5 and eight feet in height (198 cm – 244 cm).

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
