Five Mysterious Ancient Artifacts That Still Puzzle Archaeologists

Archaeologists are often described as “stumped” or “baffled” by their discoveries. But, in reality, specialists have a good grasp of what most historical objects were created for. But there are a few exceptions to this rule. 

The following list is a selection of intriguing mystery objects. They’re a great example of why digging up the past continues to hold great fascination for professionals and public alike. 

The elaborately carved stone balls found predominantly in Scotland and dating from the later Neolithic period (circa BC3200-2500) are one such mystery. 

Over 425 balls have been found. They are generally the size of a cricket ball and made from a wide variety of stones. Their surfaces are sculpted, sometimes into raised circular discs and sometimes with deep incisions defining knobs and lobes in high relief. Decoration takes the form of spirals or concentric shapes, echoing those found on pottery and monumental stones of the era.

Some have been found in burials, others in settlements. They are rarely, if ever, identical and most are found alone, so don’t seem to have been part of a set. Some appear to have been heavily handled during their lifetime. 

The original use of these stone balls has been a source of much debate, right back to their earliest discovery in the 19th century. Many were chance finds or circulated with little provenance in art collections, and have rarely been found in an archaeological context. 

These intriguing objects have recently made headlines, with a new find from Norton Disney in Lincolnshire prompting much discussion as to their function.

Dodecahedra date from the Roman period in Britain (43-410AD). About 130 have been found across the north-west provinces of the former Roman empire, each finely crafted from copper alloy. 

No representations of these objects are known in ancient art or literature. They do not conform to a standard size and rarely show use-wear which could hint at their purpose. Although armchair experts will tell you their granny used one to knit gloves, archaeologists are undecided on their intended use. 

In 1889, three carved cylinders of chalk were discovered in a child’s grave in Folkton, north Yorkshire. The Folkton Chalk Drums have geometric decoration and what appear to be eyes, noses and eyebrows. A fourth, undecorated drum was found at Lavant in west Sussex in 1993. Another, highly ornate, example was excavated at Burton Agnes in east Yorkshire in 2015. 

The Burton Agnes drum was buried with a chalk ball, a bone pin and the remains of three children – one of whom was dated to 3005-2890 BC. 

The motifs on the drums are part of an aesthetic tradition also found on the Neolithic stone balls. Despite their name, chalk drums are unlikely to have been played as musical instruments and do not show wear associated with percussive use. 

Some researchers have connected their circumferences with a standardized of length known as the “long foot”. Some think they were references in stone to perishable containers such as lidded wooden jars or baskets. Others have tried to link the geometric markings to astronomical observations. But their presence in the graves of carefully buried children seems to suggest a more sensitive explanation. 

The bronze age was a time of exceptional gold-working. Highly decorative personal ornaments were crafted from gold sheet and wire. These small penannular (open) rings date from the late bronze age (circa BC1000-800) and are found in Ireland, Britain and parts of France. 

Frequently unearthed in matching pairs, they can be plain or have delicate, geometric engravings. 

Recent interpretations have suggested they could have been nose rings, earrings or hair ornaments. None of these explanations is terribly satisfactory, as various elements of their design would make the rings difficult or uncomfortable to wear. 

What we need is context – like the recent discoveries at Boncuklu Tarla, in Turkey, of burials with facial jewelry found close to skulls. 

Cosmetic grinders are small copper alloy kits made in two parts. One half is the “mortar” (a long and curving grooved receptacle) and the other is the “pestle” (either rod-like and pointed, or arched into a “rocker” shape). They often have loops for suspension and human or animal-shaped terminals.
