Medicine for the Material World
Archaeometry, EarlyView.ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...

Chasing the perfida Albione: Anglo‐Italian productivity gap in the late 1930s
The Economic History Review, EarlyView.Abstract This paper presents new estimates of Anglo‐Italian labour productivity levels in manufacturing in the late 1930s, derived using the standard single‐deflation approach. The findings confirm a substantial productivity gap between Italy and the United Kingdom at the aggregate level, alongside pronounced intersectoral heterogeneity.
