The stair which divides the Hemicycle Terrace leads to the Terrace of the Arches with Half-columns (V), also symmetrically planned on the axis of the stair. There are nine deep arches on either side of the stair. Possibly these were stalls for the various guilds--wine merchants, wagoners, cooks, weavers, garland-makers, second-hand dealers, money-changers--who, as we know from inscriptions, made dedications to Fortune, and had a financial interest in her Sanctuary. Here again close observation has enabled the excavators to tell exactly how the façade of this terrace looked when it was new. The even-numbered arches are narrower and lower than the odd-numbered ones, are left rough within, and are floored with a pebble fill, from all of which it is inferred that they were not meant to be seen. Sills found _in situ_, and uprights, cornices, and volutes, found on the Hemicycle Terrace, where they do not fit into the architecture, and therefore must have fallen from above, can be restored as blind doors set in the walls which closed the even-numbered arches. Small travertine panels, with a molded surround, and a cornice above, found on this terrace, will have been set into the wall on either side of the blind doors, at lintel level. The same decorative motif was found in place on the back wall of the basilica area in the lower zone. The repetition of motif makes an aesthetic link between the two levels. The odd-numbered arches are mosaic-paved and plastered, and were therefore meant to be visible. Enough remains in place to show that the profile of the arch was set with tufa blocks supported on pilasters. These alternating open arches framed with pilasters and closed arches with blind doors all supported an epistyle and cornice which in turn supported the parapet of the Cortina Terrace above.
