Methodology

T-92 will be excavated stratigraphically.  Loci will be used to distinguish discrete events in the creation of the archaeological record, with new soil types, architectural features, and significant changes in the materials recovered warranting the creation of new loci. Any changes in soil type, artifact types or quantities, or the appearance of architectural features will be noted in the trench book and a new locus will be defined, measured, photographed, and recorded.  Additionally, the baulk walls will be trimmed regularly in order to gain a better understanding of the stratigraphy.

The standard method of excavation within each locus will be as follows.  In general, pickaxes will be used to break up soil; if a more sensitive method of excavation is needed, handpicks or trowels may be used for this purpose.  Soil then will be sorted by hand and with trowels.  Sorted soil will be discarded in a dirt dump located approximately 30 meters to the southeast of the trench.

Any terracotta roofing tile found will be counted in bowls with a diameter of 28 cm at its widest point, 18 cm at its narrowest point, and a maximum depth of 11 cm.  Once counted and recorded, these shall be discarded in a tile dump located approximately 10 meters to the northwest of the trench.  Any pottery or bone found will be counted on site and brought down to the magazzino in latte boxes for cleaning and further study. 

For all special finds, which will include all chronologically diagnostic artifacts, weaving equipment, full profiles of ceramics and roofing tiles, decorated pottery, decorative architectural elements, cut or worked bone, or any other artifact considered noteworthy, coordinates and elevations relative to the master grid will be recorded, as well as the locus from which an artifact is recovered, a brief description of the artifact, and the date of recovery. Any artifacts discovered from cleaning the baulk walls will be designated as Locus 0.

A fixed elevation datum point will be established in a tree located to the north of the trench, with an elevation of 28.88 m.AE.  Special finds are then sketched in the trench book on site and sent to the magazzino for cleaning, analysis, and possibly for cataloging.  Any supplemental special finds found in the magazzino will be designated an approximate range of coordinates and elevations.  

Excavation methods may change throughout the course of the season, as the types and amounts of material found as well as the geology and topography of the trench ultimately determine the best excavation method. Any changes to the methodology will be noted in the narrative.
