Thousands of artifacts bearing Indus Script, a more than 4,000-year-old writing form tied to the prehistoric Indus Valley Civilization, have been discovered over the past century. However, the meaning of these ancient hieroglyphics has remained a mystery to anyone looking to decipher them.
Although a study published in the Proceedings of the National Academy of Sciences identified patterns in the symbols taken from different artifacts bearing this text, the language remains a mystery.
In fact, some archaeologists have questioned whether the script represents a language at all, or "merely pictograms of political or religious icons," as reported in a related release from Science Daily.
With the discovery of sequences and patterns in the script, however, those looking to decode these ancient texts are more confident that the codes reflect an underlying logic of a verbal system.
