Phase Description	Phase VII: Roman mid CE 2nd c. repairs following a more collapse. Building of the Propylaeum Central...
Description	This step is later than the limestone pavement of Locus 10. It is comprised of reused blocks that are two courses in height set as headers. It provides a step between the higher elevation of the north side of Trench 81 to the Locus 10 limestone floor pavement level, which we assume makes it a later addition to the complex.
Top (m)	Opening elevation: 1.60 m below Sub datum 3/81 or 892.830 m.
Definition	Step between Locus 10 in the north and the Ceramic Pavement of Trench 87 in the south
Combined with	The Ceramic Floor Pavement of Trench 87. It is located at the same elevation.
Phase	VII
Bottom (m)	Closing elevation: + 0.28 m above Locus 10 Pavement or 892.550.
Underlies	Debris and soil of Loci 1, 8, and 9.
Size	This step is 0.28 m in height above the Locus 10 limestone pavement. It is comprised of six reused slabs—except for one under bedding block that is a reused cornice fragment. It extends from the west wall of the trench across to the east wall, thus it is approximately 5.90 m in east west width.
