Building m Harris Matrix

The Harris Matrix summarizes stratigraphic relationships among excavated contexts and groups of contexts that DAACS staff has identified as part of the same stratigraphic group. Stratigraphic groups and contexts are represented as boxes, while lines connecting them represent temporal relationships implied by the site's stratification, as recorded by the site's excavators (Harris 1979).

Stratigraphic groups, which represent multiple contexts, are identified on the diagram by their numeric designations (e.g. SG09), followed by descriptions of them (e.g. "MRS4 Occupation Layer"). Contexts that could not be assigned to stratigraphic groups are identified by their individual context numbers (e.g. 346/347E).

Contexts associated with the Mulberry Row Tree Planting excavations in the mid-1990s are not included in the Harris Matrix. Context descriptions were sufficiently different that depositional relationships between the main Building m excavations and those aimed at uncovering the tree plantings could not be correlated. 

Boxes with color fill represent contexts and stratigraphic groups with ceramic assemblages large enough to be included in the DAACS seriation of the site (see Chronology). Their seriation-based phase assignments are denoted by different colors, to facilitate evaluation of the agreement between the stratigraphic and seriation chronologies. Grey boxes represent contexts that were not included in the seriation because of small ceramic samples.

This Harris Matrix is based on data on stratigraphic relationships recorded among contexts in the DAACS database. It was drawn with the ArchEd application. See http://www.ads.tuwien.ac.at/arched/index.html.

See Building m Chronology for stratigraphic and phase information.
