The boring documents are often the most important.
“it is difficult to overstate the value of the papyri we do recover from Egypt. Documents containing census and tax information can give us important clues about the structure of ancient households (revealing, for instance, a lot of complex composite households). Tax receipts (particularly for customs taxes) can illuminate a lot about how Roman customs taxes (portoria) were assessed and conducted. Military pay stubs from Roman Egypt also provide the foundation for our understanding of how Roman soldiers were paid, recording for instance, pay deductions for rations, clothes and gear.”
