RIBBED BOWL of  Hans van Rossum



Late 1st century BC – mid-1st century AD | Eastern Mediterranean

Size↑5.5 cm | ø 12.5 cm | Weight 190 g

Technique: Sagged, tooled and lathe-cut. Rotary-polished on interior, top and outside of rim. Fire-polished on rest of exterior. The ribs were possibly formed using a fork-like tool to push against the hot surface of the glass, probably when the disk was still flat. Sometimes, it is possible to see groups of three or four parallel ribs on these bowls.

Classification: Isings 1957 form 3c, bowl with ribs on the sides only

Description: Translucent manganese colored glass. Shallow bowl, rounded by grinding, flares up and slightly out from body which bulges, then curves in towards concave bottom. On exterior forty-seven irregular ribs round the sides, more or less vertical, from just below rim, tapering off towards bottom, most disappearing before centre; on interior lathe-cut groove, 1.4 cm. below rim.

Condition: Intact, perfect condition

Remarks: Manganese compounds were used by Egyptian and Roman glassmakers, to either remove color from glass or add color to it. The use as glassmaker soap continued through the middle ages until modern times and is evident in 14th century glass from Venice. This process was difficult with regards to quantities of manganese in combination with atmospherically circumstances. That is the reason that very often the manganese colored vessels contain streaks of lighter to almost colorless glass. This bowl shows the result of this complicated production-process.  Goldstein (1979) suggests that this type of bowl falls somewhere between the thick walled, heavily tooled vessels of Hellenistic tradition and the thin-walled vessels of the mid-1st century AD.

Mid-1st century AD | Eastern Mediterranean or Italy

Size↑6.5 cm | ø 4.5 cm | Weight 26 g

Technique: Free blown, picked-up opaque white chips; handles applied

Classification: Barag 1970, vol. 2, pl. 37, type 9.1

Description: Aryballos of thin translucent blue glass with flecks of opaque white color, this so called splashed glass is a much more elaborate and earlier product than the well- known aryballoi. This oil flask has a globular body resting on a flattened base, a cylindrical neck. The rim folded outward, downward, upward and inward to form a collar-like rim. Two handles applied on the shoulder, drawn up and attached to the neck. The handles in translucent light blue glass. The bottle as a whole decorated with random ”splashes” of opaque white glass. No pontil mark.

Condition: It is difficult to determine whether the body has some very fine hairline cracks, or that this is due to the composition of the splashed glass. (Craquelé)
Remarks: These splashes were produced by rolling a bubble of (blue) glass over a marver covered with shards and chips of colored (white) glass. The bubble of glass mixed with the shards and chips would then have been reheated to make it ready for blowing. The chips melt flush with the surface and change shape when the glass expands; round at the greatest diameter, elongated vertical in the neck. ”It has been suggested that this technique may have been developed to imitate the more costly mosaic glass. An exceptional example of a rare technique of decorating ancient glass. Many of these glasses are found in the Aegean area and in South-Russia.” (Whitehouse 1997) On the backside of the stand a brown-colored paper label with the following text: ”Amphora, röm. Kaizerzeit 1 Jh post – OP S 141 rejo’’.

Large square Roman bottle

1st – 2nd Century A.D., (Isings form 50B) Rhineland (Germany)
H = 24.8 cm, D = 9.5 cm

Condition: Intact

Remarks: C.Isings/P.L.W. Arts: ‘Mold-blown prismatic bottles with square, rectangular or circular bodies were used to transport liquids all over the Empire. The majority were mold-blown, often with relief decoration on the base, especially concentric circles (see picture) or other geometric motifs and occasionally with lettering. In the Western Roman Empire cremation was practiced. Sometimes bottles like these were also used for cinerary purposes. This particular large bottle still has remains of bones inside. According to Fleming (1997) its narrow neck makes it an unusual, but not unique choice for use as a cremation urn.

Provenance: Private Belgian collection

Exhibited: Museum Honig Breethuis (NL) ’Fascinating luxury of Antiquity’, 12 November 2011– 30 January 2012 , exp no. 39

J. Paul Getty Museum

The J. Paul Getty Museum has two beautiful locations with magnificent views, grounds and architecture structures, the Getty Villa in Malibu and the Getty Center in Los Angeles.  Click on this link for the J. Paul Getty Museum web site.

Getty Center in Los Angeles

The Getty Center in Los Angeles houses European paintings, drawings, sculpture, illuminated manuscripts, decorative arts, and European and American photographs. The European glass at Getty Center covers a range in date from the late Middle Ages to the late seventeenth century.

Getty Villa in Malibu

Getty Roman Villa in Malibu is part of The J. Paul Getty Museum.  The Getty Villa is modeled after a first-century Roman country house, the Villa dei Papiri in Herculaneum, Italy.  The Villa dei Papiri was buried by the eruption of Mt. Vesuvius in A.D. 79, and much of it remains unexcavated. The Getty Villa houses approximately 44,000 works of art from the Museum’s extensive collection of Greek, Roman, and Etruscan antiquities, of which over 1,200 are on view. To see additional pictures of the Getty Villa glass collection click on this link.  **Glass at Getty Villa in Malibu in our Study Gallery. This additional link is to a clip on the Villa conduction.

Oppenlander Ancient Glass Collection

In 2003 the Getty acquired more than 350 works of ancient glass from the private collection of Erwin Oppenlander. This collection is remarkable for its cultural and chronological breadth.  The Oppenlander collection is the bases of a new exhibition called Molten Color at the Getty Villa.
