The regular shape of the cut (SUs 2210 and 2027) and the fact that it is centered within the Opus Signinum surface (SUs 2026 and 2178) suggest that it may pertain to the spoliation of a feature resting on the Opus Signinum pavement. During post-excavation study, this feature was reinterpreted as a shallow cut in the Opus Signinum pavement that likely resulted from systemic spoliation in Space 3.
