Environment and Society in the Long Late Antiquity cover

In this chapter of Environment and Society in the Long Late Antiquity, Timothy Newfield inquires on the influence of climate on disease in Late Antiquity. He looks at natural archives of pre-instrumental temperature and identifies a correspondence between a significant summer cooling in the the 6th and 7th centuries and the appearance of the Justinianic Plague in the Mediterranean region. Drawing on principles from landscape epidemiology, this paper marries textual evidence for disease with palaeoclimatic data, in order to understand how gradual and dramatic climatic change, the 535–50 downturn especially, may have altered the pathogenic burden carried in Late Antiquity. Particular attention is paid to the Justinianic Plague, but the potential impacts of a changing climate on malaria and non-yersinial, non-plague, epidemics are not overlooked.
