The cuneiform writing system originated in Southern Iraq in the mid-to-late 4th millennium
The cuneiform script1 has no punctuation, no equivalent of capital letters, and spaces are not normally left between words (though Old Assyrian frequently used a single vertical wedge as “word divider”). Sight-reading cuneiform, at least in Sumerian and Akkadian, and particularly for complex writings such as poetry, was probably a process of “fits and starts,” and not as smooth as sight-reading is for us today.
