Abstract The medium of papyrus, a ubiquitous, state-sponsored product in the Roman world, was turned by the empire’s loss of Egypt in the 630s–640s into a comparatively rare, high-status good in the early medieval northern Mediterranean (though not in the early caliphate, where it continued to have more or less the same value and associations as it had in the Roman period). The significance of papyrus altered radically as its economic value outside the Islamicate world shifted from a relatively easily obtainable, state-sponsored bulk product to a commodity available only at a few well-connected, wealthy centres: probably Constantinople and certainly Rome. The papacy continued to use this now precious commodity for its written communications. This was a crucial strategy in projecting its unique claims to authority across Latin Europe through the changing world of the late seventh to early eleventh centuries.
Goodson et al. (Sun,) studied this question.
