The various statues mentioned in the text can be seen here. It was just by scrolling through some of these pictures that the author noticed that the statues had a wristband with something interesting on the band. The readers can view these photographs for themselves and make their own conclusions. The pictures were from carvings from the Middle East. Different writers suggest these carvings represent different causes. What this author notices is that the band, and the device or thing on the band, have a similarity.
Here the device on the wrist has ten divisions on a circular background. While the picture below shows the device having three divisions on a square shaped face. Notice the unusual device both subjects are holding, and that they are holding it exactly the same way and pointing it in the same manner.
