As we are trying to open the east doorway to the garden of the peristyle house, we have had to dig down rather deeply. In so doing, we discovered that the builder of the garden cut some stairs into the bedrock, using basalt ashlars as treads, to create a staircase to the garden. So far, five steps are visible along with the bedrock to the left. It is a lovely spot, and we still have some depth through which to dig.
