I am not sure that I will be very helpful, but I grabbed my Athenian Vase Construction: A
Potter's Analysis by Toby Schreiber book. I also
ran a couple Internet searches. My comments reflect this and what I know about
pottery in general.
-the foot of this example is a key to
identification. Various
pottery items have different
types of feet or, in some cases, no feet at all. This item is not large like a typical
amphora, but it strikes me as a storage vessel rather than a polished serving piece, although it could be a
cup (but see next item). This foot looks like an echinus foot to me, that is a guess from the pictures. The following I have seen with feet like these: Some
amphora, some
hydria, Deianeira-type
Lekythos, Sixth century
Lekythos,
Oinochoe Shape 10 (maybe).
-The interior looks rough. That could be because of earthen encrustations or it may have been made that way. If it was made rough, it indicates a storage vessel probably with a rather small opening. Finishing these smoothly, especialy inside, was not as important as for a nice serving
dish like a
kylix.
-Finally, the thing that most puzzles me is the flat
side. Pure conjecture on my
part, but I wonder if it was made to hang on a wall or something. Usually, or always,
pottery would not become flattened like this after it
had been fired and completed. It would rather break at that point. I have not found any vessels with flat sides, but that doesn't mean there aren't any. We also don't know what the item looks like all the way to the top.
I am not an expert, but have done some study, so I went ahead and posted this in hopes it might be helpful in some way.
