Look at the definition of “magazine” instead. Nothing in it stipulates that it needs to be printed, to contain text and/or visuals, or to appear periodically. It’s Arabic, this time, from makhzan – for storehouse, filled with goods, often with ammunition.
We might say that there are two sections through the substance of the world: the longitudinal section of painting and the cross-section of certain pieces of graphic art. The longitudinal section seems representational; it somehow contains the objects. The cross-section seems symbolic; it contains signs. Or is it only when we read that we place the page horizontally before us? And is there such a thing as an original vertical position for writing—say, for engraving in stone?
