The world’s first complex writing form, Sumerian cuneiform, followed an evolutionary path, moving around 3500 BCE from pictographic to ideographic representations, from the depiction of objects to ① that of abstract notions. Sumerian cuneiform was a linear writing system, its symbols usually ② set in columns, read from top to bottom and from left to right. This regimentation was a form of abstraction: the world is not a linear place, and objects do not organize ③ themselves horizontally or vertically in real life. Early rock paintings, thought to have been created for ritual purposes, were possibly shaped and organized ④ to follow the walls of the cave, or the desires of the painters, who may have organized them symbolically, or artistically, or even randomly. Yet after cuneiform, virtually every form of script that has emerged has been set out in rows with a clear beginning and endpoint. So ⑤ uniformly is this expectation, indeed, that the odd exception is noteworthy, and generally established for a specific purpose.
