Small Phiale
The small phiale has a raised central umbo, 2.25 cm in diameter and 0.6 cm high, that is hollow on the underside. Its flattened rim is 0.85 cm wide. The umbo is surrounded by a series of raised concentric bands on the interior; only two are visible on the underside, but these do not clearly correspond to the lines on the interior. The bottom of the phiale curves away from the depression of the umbo. There is a thin concentric line around the exterior just below the rim.
