Today’s Calliope’s Writing Tablet post is brought to you by the letter B ~
B for Baghdad Battery
One of the more unusual artifacts discovered on an archaeological dig turned up approximately 20 miles outside of Baghdad, Iraq in 1936. At first glance the finds appeared to be simple clay jars with iron lids and asphalt seals. They stood several inches tall and each had a copper tube with an inserted iron rod down the center. No one gave them much attention at the time.
Three years later, German archaeologist Wilhelm Konig was rooting around the stored antiquities in the National Museum of Iraq. Upon finding these odd vessels he drew a rather startling conclusion. The jars looked like galvanic cells — in other words — batteries. Residue showed the jars had held slightly acidic liquid.. perhaps wine, vinegar, or citrus juice. The different metals involved would react to the acid and produce a mild electric current. Reconstruction of this odd device proves it generates a current between 0.4 and 1.9 volts.
There is some speculation among people who study such things that the Baghdad batteries could have been use medicinally for pain relief in the same manner electrical current is used today. Another opinion suggests they were used for electroplating. Whatever these inventions were used for, their modern counterpart didn’t come about until 2000 years later.
This explains a likely use for the Baghdad battery.
This offers a peek into the battery assembly should you care to make one
yourself. How cool is that?

Authors’ lives outside of the books we write can be as interesting as the worlds we create. One of the more unusual things my husband and I have done was lead wild foods programs for Chicago’s Field Museum. For this event I’ll be sharing my recipes. I hope you stop by. You may have delicious ingredients waiting in your backyard. :)
Here’s one for today:
