interpret the results of projects that u6lize digital components and methodologies • To explore the use of network analysis in an archaeological seNng • To study how the consump6on of intoxica6ng substances contributed to the social stra6fica6on of early socie6es • This was accomplished by studying the distribu6on of poQery rela6ng to feas6ng across the Bronze Age Aegean
The presence of luxury vessels that were reserved for the ac6vi6es of the wealthy would signify the presence of an upper class, who mobilized resources and oversaw the centralized economies of this seNng • The middle/late Bronze Age was a period of transi6on from a more-‐or-‐less egalitarian society to an increasingly hierarchical chiefdom structure with an elite class. • Feas6ng is an interes6ng example of conspicuous consump6on, through which the leader reinforced his leadership and links to the his allies, while also emphasizing his dis6nc6on from the rest of the community.
• Network analysis is a method to find rela6onships between en66es that are not plainly obvious. • This set of methods is especially useful in archaeology, since the accumula6on of intertwined data is difficult to analyze and interpret • It provides a systema6c approach to examine social rela6onships in a quan6ta6ve way. • Network analysis can be used to examine the rela6onships between any kinds of variables • In the social sciences, interpreta6on requires the considera6on of the nature of what nodes actually represent • When working with objects, they must mean something to the people who used them
– Problems included uneven depths of excava6ons, limited access to reports • Total of 5669 vessels were recorded – Of them, 2995 vessels were included in the analysis. • Ten sites were included in the analysis • Varia6ons within a poQery type were ‘lumped’ together • Luxury poQery is easily classifiable by func6on to the ac6vi6es of the elite within a hierarchal society.
• Metrics used: • Degree -‐ The degree represents the number of connec6ons that a par6cular node is directly associated with. • Betweeness Centrality -‐ The betweeness centrality is the measure of how oaen a par6cular node acts as an intermediary between the paths of any two other nodes in a given network. This is usually expressed as an index value. • Modularity -‐ This metric iden6fies small sub-‐communi6es of nodes within the overall network. Densely packed groupings are oaen connected with less dense intermediaries. In social network analysis, the iden6fica6on of these sub-‐communi6es oaen reflect real-‐world applica6ons.

• Applied to 34 Bronze Age loca6ons of the Aegean • Included factors that ‘push’ or ‘pull’ people to travel to certain sites – Access to resources, popula6on dynamics, carrying capacity • Also incorporates wind and sea currents, sailing technology and physical loca6on • Tim Evans, Ray Rivers and Carl KnappeQ, “Interac6ons in Space for Archaeological Models,” 2011 • Carl KnappeQ, Tim Evans, and Ray Rivers, “Modelling Mari6me Interac6on in the Aegean Bronze Age,” An3quity 82, no. 318 (2008): 1009–1024.
luxury poQery types, based on their co-‐presence at various archaeological sites • Two separate modules are displayed • Alabastron & S6rrup jar have high centrality values and link these dis6nct communi6es
Sciences • It is very important to establish goals early on • Data collec6on must suit these goals • Good quality data is crucial, since the analysis and interpreta6on are dependent on it • If the interpreta6ons are of social interac6ons, the dataset must be representa6ve of this – Ar6facts must mean something to the people who used them • The digital humani6es are about extending the reach of tradi6onal methods of academic research by using technology, working in an interdisciplinary environment, facilita6ng collabora6on with other scholars, and the publica6on of results in an open and accessible manner
