Writing system
Writing systems were preceded by proto-writing, systems of ideographic and/or early mnemonic symbols. The best known examples are:The invention of the first writing systems is roughly contemporary with the beginning of the Bronze Age in the late Neolithic of the late 4th millennium BC. The Sumerian archaic cuneiform script and the Egyptian hieroglyphs are generally considered the earliest writing systems, both emerging out of their ancestral proto-literate symbol systems from 3400 to 3200 BC with earliest coherent texts from about 2600 BC. It is generally agreed that Sumerian writing was an independent invention; however, it is debated whether Egyptian writing was developed completely independently of Sumerian, or was a case of cultural diffusion.
Palaeography
The oldest example of minuscule cursive writing that has been discovered is a letter on papyrus, found in Egypt, dating from the 4th century. This marks a highly important date in the history of Latin writing, for with only one known exception, not yet adequately explained—two fragments of imperial rescripts of the 5th century—the minuscule cursive was consequently the only "scriptura epistolaris" of the Roman world. The ensuing succession of documents show a continuous improvement in this form of writing, characterised by the boldness of the strokes and by the elimination of the last lingering majuscule forms. The Ravenna deeds of the 5th and 6th centuries exhibit this hand at its perfection.
