Observations The tufo floor seems to be most easily defined by its northern and eastern limits - 1187, 1186. The western edge is interrupted by what may be a cut. North -South visible length is 426 cm, east to west has a visible width of 300 cm. SU 1165 soil layer covering floor. Special find 587 (loom weight) and 594 (loom weight). This SU was excavated further in 2012, the new limits were recorded by Topo. Please add this comment to database, because there was no room on the SU sheet anymore.
Position Located at the southernmost edge of sector, immediately south of 1187, continued briefly past 2010 excavation limit in southwest along 1058
Shape horseshoe-ish
Structure Floor Type Other crushed tufo
Structure Dimensions 300 cm east-west, 426 cm north-south
Structure Description The tufo floor is fairly compact and has a light brown color. Has a slight decline in the western direction. The SU remained in situ - was not excavated - in 2011 a small section - approximately 135 x 90cm roughly - excavated in southeast strip along 1058. 2011: rubble especially towards north and large charcoal deposit also in north; thickness increases toward south. Interface with layer below is sharp.
Non-Soil Sample Type charcoal, mortar
Finds Observations strange ivory fabric with well-sorted, small black inclusions

  • Current observations show that the foor has been cut into by 1155 and the rubble wall 1163. The wall's southernmost context has yet to be excavated but given that no southern wall has been found one can believe that the floor continues south. In relation to 1188 it is now clear that the floor abuts the cystern slabs. Also, approximately 300cm west of 1186 the floor abruptly stops. The discontinuation of floor seems to have been caused by a disturbance in the soil layer. Excavation will continue to determine if this is a cut or some other intended form of construction. Finally, layer removal will continue along 1162 to see if there is tufo floor on the other side of the disturbance. Note: floor may not be final product but a last vestige of the actual thing. Note: floor was found on western side near 1135. Excavation in 2011 of a small strip in south-west corner revealed a rocky/rubble-y sub fill of the tufo floor containing much pottery and tiles, some animal bones, 1 large deposit of charcoal and a loom weight (special find 587). Also revealed tufo slabs covering channel along SU 1058, remaining in situ).
