It’s not the large cabochon gemstone that opens on a hinge to reveal a secret compartment filled with tasteless, odorless, deadly iocane* powder of your imagination. This ring has a more subtle, and therefore effective, design. It’s made out of modest bronze and has a hollow cartridge welded to the bezel. It’s finely crafted with a circular granulation detail around the top and five cylinders that look like stacked pennies going up the side. There’s a small hole on the side of the ring between two of the cylinders through which poison could be introduced into the hollow chamber and, when the propitious moment is at hand, into the food or beverage of your benighted target.Text and image from The History Blog (where there are more details about relevant local history).
Its size suggests that it was made for a man to wear, probably on the little finger of the right hand. Since the hole is on the left side, it would be concealed by the ring finger next to it. A quick lift and tip of the pinkie and poisoning accomplished. It’s a much stealthier approach than having to open a splashy begemmed lid and turn your hand upside down without anyone noticing.
The ring was found by archaeologists excavating the remains of a 14th century fortress on Cape Kaliakra on the Black Sea about seven and a half miles from the town of Kavarna in northeast Bulgaria. Bulgaria’s National Institute of Archaeology has been excavating the fortress site since 2011. Amidst the remains of the 14th century walls, water pipes, baths and fortress, archaeologists have found more than 30 gold jewels, pearl earrings, rings set with precious and semiprecious gems. This ring is the only one made out of bronze discovered on the site.
