2. Flexible Glass: A Substance Too Precious
Three ancient accounts of a substance known as vitrum flexile, flexible glass, are not clear enough to determine that this substance actually existed. The story of its invention was first told by Petronius (63 AD).
3. An Antidote to All Poisons
A so-called “universal antidote” against all poisons was said to have been developed by King Mithridates VI of Pontus (who reigned 120–63 BC) and perfected by Emperor Nero’s personal physician. The original formula was lost, explained Adrienne Mayor, a folklorist and historian of science at Stanford University, in a 2008 paper, titled “Greek Fire, Poison Arrows & Scorpion Bombs: Biological and Chemical Warfare in the Ancient World.” But ancient historians told us that among its ingredients were opium, chopped vipers, and a combination of small doses of poisons and their antidotes.
4. Heat-Ray Weapon
Greek mathematician Archimedes (212 BC) developed a heat-ray weapon that defied the skills of Discovery Channel’s “Mythbusters”. Mayor described the weapon as “ranks of polished bronze shields reflecting the sun’s rays at enemy ships.”
5. Roman Concrete
The vast Roman structures that have lasted thousands of years are testaments to the advantages Roman concrete has over the concrete used nowadays, which shows signs of degradation after 50 years.
6. Damascus Steel
In medieval times, swords made of a substance called Damascus steel were being produced in the Middle East out of a raw material, known as Wootz steel, from Asia. It was perplexingly strong. It wasn’t until the Industrial Revolution that metal so strong would be forged again.
