Produced nearly 4,000 years ago, more than 1,000 years before the invention of any form of magnifying glass, the dagger was decorated with 140,000 tiny studs. The ultra-fine craftwork entailed extremely tiny components such as microscopic gold pins and gold wires.
According to optic experts, only children and teenagers, and those adults who had become myopic naturally or due to the nature of their work as children, would have been able to create and manufacture such tiny objects. The eye-stressing work would have blinded most child workers.
The image shows how the studs are placed in straight lines and the heads overlap each other like fish scales.
