Description A row of tabernae is visible on the left side of the fragment which open up to a possible covered walkway bordered by an arcade. To the right of this arcade a street runs top-bottom through the middle of the fragment. This street is flanked on the right by T-shaped piers running parallel to the road, perhaps also indicating a covered walkway in front of the row of tabernae visible to the right. One taberna has an internal staircase.

Identification: alongside the Circus Maximus The fragment was matched with fr. fn9 by the Stanford team. Four vertical rows of distinct parallel incised features on fragments fn9 and 351 caused the boundary incision matching algorithm to assign a very high score for the correspondence between these two fragments (Koller-Levoy 2005, fig. 8). Manual observation of the three-dimensional computer models of the fragments allowed to infer that the fragments lie immediately adjacent to one another, based on the strongly corresponding shape between the fractured edges along the proposed interface (fig. 9). Further evidence of the match is evident in the spacing of the rooms, dashed line, and row of T-shaped piers that traverse the two fragments, including the recurrence of stairways in every third room along the right side of the central street. The topography depicted on the combined fragments fn9 and 351 is suggestive of the architecture along the sides of the Circus Maximus , as shown on other fragments (cf. frs. 8bde, 8c, 8fg). By process of elimination, it seems most probable that fn9/351 should be positioned on slab VII-13# containing fr. 9 and the bottom half of the Circus Maximus (Koller-Levoy 2005, 10c-d). Based on the similarity of the architecture on fr9/351 with that on frs. 8b-g, a position is proposed on the lower left side of the Circus Maximus rather than the right, as shown in fig. 11.

Significance This fragment possibly depicts the commercial elements next to the Circus Maximus, as well as what seems to be a major thoroughfare along side the circus, emphasized by red paint.
