Proto-writing

Proto-writing consists of visible marks communicating limited information. Such systems emerged from earlier traditions of symbol systems in the early Neolithic, as early as the 7th millennium BC in China and Southeastern Europe. They used ideographic or early mnemonic symbols or both to represent a limited number of concepts, in contrast to true writing systems, which record the language of the writer. Analysis in 2022, led by Bennet Bacon, an amateur archaeologist, showed that lines, dots and "Y"-like symbols on Upper Palaeolithic cave paintings were used to indicate the mating cycle of animals in a lunar calendar, the markings found in over 400 caves across Europe were compared to the mating cycles of the animals with which they were associated, showing a correlation with the month of the year in which the animals depicted in the cave paintings would typically give birth. The markings were 20,000 years old predating any other equivalent writing systems by 10,000 years. In 2003, tortoise shells were found in 24 Neolithic graves excavated at Jiahu, Henan province, northern China, with radiocarbon dates from the 7th millennium BC. According to some archaeologists, the symbols carved on the shells had similarities to the late 2nd millennium BC oracle bone script. Others have dismissed this claim as insufficiently substantiated, claiming that simple geometric designs such as those found on the Jiahu shells cannot be linked to early writing. The Dispilio tablet is a wooden tablet bearing inscribed markings, unearthed during George Hourmouziadis's excavations of Dispilio in Greece, and carbon 14-dated to 5202 (± 123) BC. It was discovered in 1993 in a Neolithic lakeshore settlement that occupied an artificial island near the modern village of Dispilio on Lake Kastoria in Kastoria, Western Macedonia, Greece. The Vinča symbols (6th to 5th millennia BC, present-day Balkans) are an evolution of simple symbols beginning in the 7th millennium BC, gradually increasing in complexity throughout the 6th millennium and culminating in the Tărtăria tablets of c.
