Figured I should add this question to this topic because the title is broad. In reading the translation of the Epic of Gilgamesh, the translator used periods to separate into sentences which I can understand. But other punctuation such as exclamation points, were there marks used in order to express this in cuneiform or is this the person’s own translation of the emotions? In the early form, it looks like rectangles were used as periods to separate ideas. Then, Akkadian is similar to modern forms of writing with lines going horizontally and then spacing vertically. It’s hard to see any marks on them.
