DECANTER WITH RIBS of Joop van der Groen



Roman Empire │ 1st century AD, probably 2nd – 3rd quarter
Size: ↑ 15,6 cm; Ø max. 9,6 cm; Ø rim 3,4 cm. │ Weight: 87 gram

Technique: Mold blown and free blown. Tooled.
Classification: Isings (1957) form 71.
Description: Transparent light aubergine coloured glass. Body first mold blown with ten ribs and then further free blown. Free blown cylindrical neck. Rim folded outward, upward and inward. Base flat, lightly pushed in upward. No pontil mark.
Condition: Intact with iridescence and with some encrustation inside.
Remarks: In the 1st half of the 1st century AD coloured glass was strongly fashionable. Later on in that century bluish-green glass was getting more popular.
Bluish-green is the basic colour of Roman glass. This has been caused because sand (the main element for making raw glass) has been polluted by iron oxide. By addition of some percents manganese oxide in the raw glass the colour changed into aubergine / purple.
Provenance: 2011 Atticard Ltd, London.
Reference: Kunstwerke der Antike (Cahn Auktionen AG Basel), Auktion 7, 03-11-2012, no. 83 ( till 1986 in the private collection of P.M. Suter-Pongratz, Basel, no. 65).
Isings (1957) writes about form 71 “Of this type only a few specimens are known, several of them found at Pompeii (Napels Museum)”.

Piriform Roman Flask of Elisabeth & Theo Zandbergen


Origin: Most probably Syria ~ 4th century AD.

Dimensions: H. 15,9 cm.; ø rim 3,5 cm.; ø foot 4,5 cm.; largest ø ~ 5,2 cm.; weight 62,9 gram.

Description: The elegant piriform body of this yellow-greenish glass is set on a hollow foot formed from the same glass gathering as the body. It is decorated with two handles made from blue glass with nipped extensions over the sides. At the top, the body narrows down to form a slightly tapered cylindrical neck with a flaring mouth being outward /inward folded rim. The pontil mark is quite visible.

Remarks: These flasks are sometimes called amphorae, but I think that is extending the meaning of amphora a bit too far. As flasks of this type are quite often present in museums and collections these must have been quite popular in those days, but what did they store in those flasks? Presumably these were on the dressing tables filled with fragrant substances and not regular household items.

Rhodian cast monochrome bowl

Rhodian cast monochrome bowl

Rhodian cast monochrome bowl

Rhodian cast monochrome bowl

Late 4th – early 3rd century BC. Rhodian.
H = 3.7 cm. Dmax = 12.2 cm. Drim = 12.2 cm. Dbase = 3.2 cm. Weight = 188 gr.

Triantafyllidis: Rhodian shallow phialai group B1.

Crack over almost entire body but not broken and complete. Slight iridescence, surface well preserved.

Cast and polished. Cut on both interior and exterior.

Almost colorless transparent glass with slight greenish tinge.
Thick walled (5 mm) shallow bowl. Outsplayed rim with rounded edge, flaring gently from almost straight sides. Wide horizontal groove (2 mm) on interior below rim, highlighting distinct carination between upper wall and rim. Slightly concave bottom encircled by a groove (1.5 mm), from where twenty one (21) elongated lanceolate petals with rounded ends radiate upward to the wall, where they are encircled by a pronounced horizontal groove that marks the junction of the lower wall and bottom. In the middle of each petal a median groove is cut.

Shallow cast monochrome bowls with slightly carinated walls at the height of the shoulder and the base of the rim were produced in Rhodian glass workshops from the late 5th century until the third quarter of the 4th century BC (Triantafyllidis). Glasswork from Rhodes in this period was influenced by glassworkers from Persia during the Achaemenid period (ca 550-330 BC) which makes it difficult to define the place of manufacture. The color of the glass, the profile of the bowl and the cutting of the radiating petals are the primary reason for defining the date and place of manufacture of the bowl: Rhodian rather than Persian.

Ex collection Joseph Uzan, Paris.

Dating: The production of these glass bowls, colorless or pale green to olive green are attributed to the period of the Achaemenid dynasty in Persia (559-330 BC).

Description: The forms of the glass bowls are copied from the Achaemenid silver and bronze shapes. They feature either embossed fluting, rosettes of pointed leaves or lobed designs on both deep and shallow bowls with flaring rims.  The shallower bowls are called phiales.

Technique: The technique of manufacture was possibly the lost-wax casting method using the finest quality glass available. Many of these bowls show signs of being cut on the exterior and also polished on both surfaces.

The following bowl drawings are from, Early Ancient Glass, Toledo Museum of Art, 1989, David Grose

Molten Color: Glassmaking in Antiquity, Karol B. Wight, The J. Paul Getty Museum, Los Angeles, 2011

The Molten Color exhibition at the Gerry Villa opened in January of 2006 and this book stems directly from that exhibition.  The glass show can be found on the blog at this link. Molten Color at the Getty Villa. The book is 136 pages, smaller size (6.5×8.5 inches) with 96 wonderful color photographs.  Don’t let its smaller size deter you, this book is packed with well written information not only about the objects but also Roman glassmaking in antiquity.
