Roman knife shapes

[Kegluneq]

Whether the lower shelf objects are bundles or racks, it strikes me that the attenuation in size from right to left in their size matches the shift in size of the knives on the next shelf up. Perhaps the visible knives are show pieces, and the bundles/racks contained the same items but in quantity? If the contents were the same as what was shown above, it would be unnecessary for them to be open as it would be understood by the viewer that that was what they were.

Edit: If that were the case, perhaps Epaphra is shown in the act of taking a knife from the second bundle/rack? The square panel could then perhaps be a locked door behind which the knives were kept. Is it possible to tell if that second panel is angled outward or not?

(Of course it could just be a case of the sculptor being a bit lazy with calculating space, as they are often wont to be in the Roman world. If that were the case, perhaps the sculptor was left handed, going by the direction of the decline in size?)
