the baghdad batteries


The oldest known Battery to mankind called “Battery Baghdad” is almost 2000 years old!

The Baghdad Battery is believed to be about 2000 years old (from the Parthian period, roughly 250 BCE to CE 250). The jar was found in Khujut Rabu just outside Baghdad and is composed of a clay jar with a stopper made of asphalt. Sticking through the asphalt is an iron rod surrounded by a copper cylinder. When filled with vinegar - orany other electrolytic solution - the jar produces about 1.1 volts. 

There is no written record as to the exact function of the jar, but the best guess is that it was a type of battery. Scientists believe the batteries (if that is their correct function) were used to electroplate items such as putting a layer of one metal (gold) onto the surface of another (silver), a method still practiced in Iraq today.

Miss the beginning? 

Your voice was raspy from the burn of whiskey, “What do you know about the Holy Lance?”

With one eyebrow arched, Steve stared at you, scoffing when you asked the question again. “You’re serious.”

“As a damn heart attack, Professor.”

He scoffed again and pushed away from his desk. “Only one problem with that, Miss Y/L/N, the Holy Lance, or Spear of Destiny as most know it as, doesn’t exist. It’s pure mythology. Even the Catholic Church has not made a claim to the authenticity of the ones in Rome and Vienna.”
