The "goblets" look like Alexandrian cups with wide mouths and narrow bottoms (like martini glasses without the stems --translator). The "knobs" looked like the apples from Keros which are slightly elongated like an egg with both ends rounded. The "flowers" look like the flowers on [top of] columns, like bowls with the lip folded outwards.
