Demotic Script

Demotic Script lasted for about 1000 years and belongs to the last period of Egyptian history. even after demotic script was introduced the hieratic script was still used, mainly for religious purposes. Demotic did, however, win out on being used in business and everyday use because it was a lot easier to write and but not as easy to read. This is because most of the forms of the characters were almost exactly alike. 660BCE was the first example of Demotic writing, while 425AD was the last known example of its use.
