Everyday letters and epistolary practice

A letter, in the ancient and medieval world, was often only half the message -- the trusted carrier delivering it held the more important half in memory, using the written sheet mainly to prove who had sent them. That gap is what makes ordinary correspondence such a rich seam for the conjectures on this page: real letters survive in genuinely large numbers, from papyrus notes in Egyptian villages to ink-on-wood tablets at the Vindolanda fort, but only from a lucky few pockets of preservation -- a couple of dry provinces and a single soggy garrison town standing in for the postal traffic of entire empires. Because the sheet was never the whole message, who addressed it, which networks of senders it moved through, and even how long it ran can all encode clues about who was trusted to carry what -- exactly what several of the linked conjectures test.

Short letter, long messenger tests whether a shorter letter correlates with a more trusted messenger carrying the rest by memory, an inverse relationship the corpus should reveal directly. The address knows the road reads the physical address itself as encoding information about the road network it travelled. The short radius of women's mail and The fort writes to the fort both look at how narrow a correspondence network actually was -- how rarely women's letters reached other women, how much of a fort's mail simply went to the next fort over -- rather than assuming letters connected freely across an ancient world's full breadth.
