Recent work at two Late Bronze Age hilltop fortresses in the mountainous volcanic terrain of Armenia provides an excellent illustration of their potential. Magnetometry revealed an unknown residential complex at Tsaghkahovit. Across the plain at Gegharot, where magnetometry was less successful, ground-penetrating radar identified terracing extending down the western slope of the hill below the fortress, greatly increasing the size of the occupied area. Combined with targeted excavations, these geophysical approaches are providing novel insights into the unusual political relations between fortress-based sovereigns and mobile subjects in central Armenia.

Surprisingly, among the identified proteins were peptides from Crimean-Congo hemorrhagic fever virus (CCHFV), a pathogen previously unknown in this geographic region and time period, as well as peptides from human blood and tissues. These results highlight the first example of a viral cause of death of at least one high-status individual from the Iron Age west-central Europe and provide the first archaeological evidence for the interment of human organs in mortuary vessels in the region. We also demonstrate the suitability and value of a proteomics approach for discovery-based residue analysis of archaeological ceramic vessels and reveal how identification of adsorbed proteins can provide insight into prehistoric mortuary practices.
