Readers will have noticed that I have been using ChatGPT to generate illustrations for my articles. Generally, the results are very good, but earlier versions had a habit of introducing anachronisms: Neanderthals accompanied by dogs and other livestock, for example, or Stone Age hunters carrying what appeared to be metal-tipped spears. Correcting these could become an amusing — and sometimes frustrating — exercise. Removing one error would introduce another, and the next attempt might restore the original mistake.
This time, however, something rather encouraging happened. For my previous article, about a Neolithic village in Serbia that archaeologists have re-examined, I asked ChatGPT to produce an impression of everyday life in the settlement. It generated an image, then identified an anachronism in its own output and produced a corrected version without my having to point out the problem. That does not mean historical inaccuracies are now a thing of the past, but it was a welcome example of checking and correction.
Naturally, this also presented an opportunity for a little fun. Below are the two images, side by side. Can you spot what does not belong in the image on the left? If you would like a helping hand — or simply want to cheat — click the button to reveal a nifty tool for comparing them.
