Archaeologists excavating the Lucone di Polpenazze site on the southwestern coast of Northern Italy's Lake Garda found a 4,000-year-old clay tablet marked with enigmatic geometric symbols on Thursday. The presence of matching signs hundreds of kilometers away prompts further study into the Bronze Age period.

Extracted from a carbon-rich soil stratum during the third week of the 2026 summer excavation season, the tablet represents a highly rare discovery due to its completely undamaged and intact condition.

This artifact should not be confused with Mesopotamian cuneiform tablets, as it lacks letters or signs from any known script. Instead, the surface displays circles, dots, triangles, along with square or rectangular motifs formed using scratching and pressing techniques.

In Italian archaeology, these objects are known as "tavolette enigmatiche" (enigmatic tablets), while in German literature they are called "Brotlaibidole" (bread loaf idols) due to their round, loaf-like shape.

Why artifact intrigues?

The last time a tablet of this type was found at Lucone was in 2019. This recent find increases the regional count of enigmatic tablets to 21, which solidifies Lucone's status as the archaeological site featuring the greatest concentration of such objects in the world.

Similar tablets have been discovered not only in Northern Italy but also across a broad swath of Central and Southeastern Europe, at sites dating back to the Early and Middle Bronze Age (roughly 2100-1400 B.C.). The recurrence of similar combinations of lines and markings at settlements hundreds of kilometers apart strengthens the possibility that these symbols belonged to a shared sign system spread through long-distance trade networks.

How tablets function?

Researchers propose several theories, including a calendar, a ritual object, a tallying device, an identity token, or even a record of exchange for the metal trade. Yet, none of these have been conclusively proven, remaining purely hypothetical. Furthermore, there is no evidence to suggest that the symbols represent a spoken language, rather than a "script waiting to be decoded," it involves a system composed of repeating standard mark combinations.

To identify common patterns across geographically dispersed tablets, researchers are using 3D scanning and digital comparison techniques. This process simultaneously helps explore possible connections linking Lucone to Central Europe and the Danube-Carpathian region.

Another factor enhancing the scientific value of Lucone is the settlement itself. Tree-ring (dendrochronology) analyses indicate that the site dates to approximately 2034-1967 B.C., with construction and repair activities continuing until the late 20th century B.C.

At one point, a major fire destroyed part of the village, causing wooden structural elements to become buried in the wet ground. This process of waterlogging and partial charring ensured the preservation of materials that would typically decay, such as wooden tools, plant remains, textile fragments, and grain.

Due to this exceptional preservation, Lucone is among the Italian sites included in UNESCO's World Heritage list as part of the "Bronze and Iron Age Lakeside Settlements around the Alps."

Offering a remarkably broad dataset, this collection of 21 tablets allows archaeologists to compare markings, manufacturing methods and discovery contexts. It is still unknown if the tablets were used to register trade, track time, or identify individuals. However, Lucone is considered the site closest to unlocking one of the most persistent archaeological mysteries of Bronze Age.
