Answer:
Harappan Civilization
Step-by-step explanation:
The Indus River Valley Civilization (also known as Harappan Civilization) was a Bronze Age society that stretched from northeast Afghanistan to Pakistan and northwest India.
Harappans are believed to have used the Indus Script, a language consisting of symbols. A collection of texts written on clay and stone tablets unearthed in Harappa, dated 3300-3200 BC, contains marks in the shape of a plant and in the shape of a trident. This Indus Script suggests that writing developed independently in the Indus River Valley Civilization from the script used in Mesopotamia and Ancient Egypt.
Up to 600 distinct Indus symbols have been found on seals, small pills, ceramic pots and more than a dozen other materials. Typical Indus inscriptions are no more than four or five characters long, most of which are very small. The longest on a single surface, less than 1 inch (or 2.54 cm), is 17 signs long. The characters are largely pictorial, but include many abstract signs that do not appear to have changed over time.
The inscriptions are believed to have been written mainly from right to left, but it is not clear whether this script is a complete language. Without a "Rosette Stone" to use as a comparison with other writing systems, the symbols remained undecipherable for linguists and archaeologists.
