This paper discusses the evolution of documentary culture in early medieval Tuscia by quantitatively examining Latin spelling charter scribes relation to following factors: time, distinction between formulaic and non-formulaic parts document, scribe’s domicile, professional status, document type. The asks what charters tells us about administrative socio-cultural changes production scribal educ...

This study provides a preliminary agro-environmental, economic and energetic analysis to critically evaluate the biomass potential ofan area of central Italy (Tuscia Romana). This area is selected as representative foragro-forestry from its orographic characteristics, climatic conditions, land use and potential energy sources. Accordingly, the model we have obtained could be used forother simil...
