The square tufo base was likely placed in its position before the surrounding structures of 7331, 7044, and 7408. It was possibly part of some structure or pilaster likely associated with similar square tufo base 7410 to its east. 7409 continued in use as a pavement of the piazza after the laying of pavement 7044. The superstructure on top of 7409 was likely removed to make it more level with the pavment of the piazza.
