Debated. The tablet has lines, dots, and shapes, and nobody has shown that they are writing.
The tablet was found at Lucone di Polpenazze, near Lake Garda, in northern Italy. It is about 4,000 years old. Tree rings date wooden posts at the village to about 2034 to 1967 BC. This clay tablet is intact. It is the third of its kind from the area now being dug, and the plain has now given 21 such tablets. The village stood in a wet basin, and a fire plus wet ground kept wood, plants, and other remains.
The page says the signs might be a calendar, a token, or a trade note, and none of those ideas is agreed.
