Poison ring found in 14th c. Bulgarian fortress

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.

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.

Some of the gold rings also have holes deliberately drilled in them, but only the ones with gemstones and none of them have hollow cartridges. According to team leader Boni Petrunova, holes were sometimes added to rings to allow the gems to “breathe.” The bronze ring is in excellent condition and intact as is. There were no gemstones in need of a breathing port, so that hole was used for other purposes, nefarious ones at that.

The location certainly lends itself to deadly political machinations.

The ring was most likely used in the conflict between Dobrotitsa, ruler of the independent Despotate of Dobrudja in the second half of the 14th century, and his son Ivanko Terter, Petrunova said. The conflict is the most likely cause of many deaths of nobles close to Dobrotitsa at Kaliakra fortress.

Kaliakra was the capital of the short-lived principality that stretched from the Danube River delta to present-day Bourgas. The peak of its power came under Dobrotitsa, who had sufficient military strength to participate in Byzantine civil wars and, allied with Venice, challenge Genoese naval domination in the Black Sea.

Dobrudja was a center of wheat production for Byzantium and it had extensive trade networks with Italy and Spain through Genoa. That connection took an unpleasant turn on occasion, like when Genoese galleys dropped off the Black Death in 1346 or 1347 before carrying their Y. pestis-laden rat fleas to Sicily and thence to the rest of Western Europe.

There was also plenty of local intrigue. Dobrotitsa and his son Ivanko had a dysfunctional relationship, to put it mildly. Their vicious rivalry left swaths of dead supporters in its wake. Perhaps this ring is responsible for some of that body count.

Other than the fact that most people are right handed, what makes you think the ring went on the right hand? Wouldn’t wearing it on the left make it more sinister?

That puppy would make a fine dent in someone’s head , if the wearer was a puncher.

I’d like to know if they could have a chemical analysis done in the chamber. (Legal disclaimer): My knowledge of poison is limited, so I’m curious as to what, in such a small amount, was typically used to ‘make problems go away’.

What kind of poison did they have back then that meets all the criteria you recited, and was instantly fatal? I can’t think of any.

Cyanide is the likeliest poison. You make it by distilling ground peach kernels. The formula was known back to ancient times. (Don’t try this at home…you really can kill yourself. Also, I haven’t given the full method.)

Arsenic would be another try, but for that size ring you’d need lots of repeat doses.

Concentrated snake poison of one sort or another is also possible.

Most reported arsenic poisonings are not caused by elemental arsenic, but by one of the arsenic compounds, especially arsenic trioxide, which is approximately 500 times more toxic than the nonlethal pure arsenic. The Borgias’ Cantarella recipe was believed to contain copper, arsenic derivatives, and phosphorus, following the trends of that time.
