Cuneiform – the birth of an interface standard?
There seems to have been something of a debate regarding a shift in assumptions about how cuneiform scripts were to be read, whether left-to-right or top-to-bottom in columns. Some argue that top-to-bottom makes more sense given certain assumptions about the way the stylus would have been held.
According to Madelaine Fitzgerald of UCLA (see the short paper in the link above) there does appear to have been a protocol to allow readers to identify the direction of reading. This involved the use of holes in the clay tablets to allow them to be held on a string – and if the tablet were raised on the string it would fall in a way that would indicated the reading direction, thus distinguishing between the earlier cuneiform scrpts of the Old period Babylonians (which ran in vertical columns) to those of the later period which ran horizontally.
And then there remains the question of why the Babylonians changed direction of their script from columns to lines. Fitzgerald gives a tantalising hint that it may have been because of the international climate of the time – ie to bring Babylonians in line with contemporary practices in other (more economically powerful) neighbours. What this seems to indicate is the application of an internationally agreed interface standard to facilitate ease of communication.
