Roman, Imperial Period, ca. 1st century CE. A wonderful example of first century ribbed cups created via mold blowing, this example has a rounded body, of rich purple hues with tinges of dark amethyst and wine, decorated by fine ribs with the ribbing ending in an arc under the mouth and a white ribbon-like band applied filament trailing around the circumference of the vessel, just above the ribs and sometimes drizzling to the upper sections of the ribs. Complementing this is a white spiral on the underside, winding around several times until resolving in a zigzag. Size: 4.125" in diameter x 1.75" H (10.5 cm x 4.4 cm)
Ribbed glass vessels represented a Roman manufacturing breakthrough - not only aesthetically but technically as well. According to the curatorial team at the Cleveland Museum of Art, "The ribs were pressed into a heated glass disk with a tool, and then the disk was heated over a convex form. The resulting bowl shape was slowly cooled and then turned on a lathe to polish the rim and apply incised detail. Finally, the bowl was fire-polished in the furnace."
Other examples of blown ribbed glass bowls with such delicate trailing (known as Zarte Rippenschale), showing the ribbing ending in arcs beneath the mouths and decorated with applied glass trail filaments gracefully spiraling around the ribs, from such esteemed collections such as the Metropolitan Museum of Art, the Getty Villa, and the Toledo Museum of Art, are featured in a blog of the Allaire Collection.

Condition
Repaired from multiple pieces with restoration over the break lines and to areas of the white trailing. Still, an incredibly rare example.
