These events allowed the Chaldeans to once more attempt to assert themselves. While the Assyrian king was otherwise occupied defending his Iranian colonies from the Scythians and Cimmerians and driving the Egyptians from Canaan, Marduk-apla-iddina II (the Biblical Merodach-Baladan ) of Bit-Yâkin, allied himself with the powerful Elamite kingdom and the native Babylonians, briefly seizing control of Babylon between 721 and 710 BC. With the Scythians and Cimmerians vanquished, the Medes and Persians pledging loyalty, and the Egyptians defeated and ejected from southern Canaan, Sargon II was free at last to deal with the Chaldeans, Babylonians and Elamites. He attacked and deposed Marduk-apla-iddina II in 710 BC, also defeating his Elamite allies in the process. After defeat by the Assyrians, Merodach-Baladan fled to his protectors in Elam.
Eventually the most cursive form of hieratic became the demotic which gives no hint of its hieroglyphic origin. By 600 BCE, the hieratic, which was used to write documents on papyri, was retained only for religious writing. The demotic became the every-day script, used for accounting, writing down literature, writings, etc. The following demotic inscription is from the famous Rosetta Stone. It bears no resemblance whatsoever to the hieroglyphic script. In fact, it is so cursive that it resembles more like the Aramaic scripts used around the Fertile Crescent at this time.
