Gaulish amphorae 2 (GAL AM 2)

Five samples

This type equates to London 555 amphora (Peacock & Williams no 59), first defined by Wheeler (1930). In France it is referred to as Haltern 70 similis (Dangréaux & Desbat 1988).

General appearance

A pale brown (7.5YR 7/4, 5YR 7/6) or pale orange (2.5YR 7/8) fabric with slightly lighter surfaces, sometimes with a greenish tinge (2.5YR 8/3, 10YR 8/4–7/4) or other light-coloured margins. The fabric is hard with a smooth fracture, and rough to harsh surfaces, depending on whether the external surface is sand gritted. Frequently the sherds are wiped, giving an appearance of bread dough (B Richardson, pers comm).

Hand specimen

This fabric generally has a well-sorted groundmass in a micaceous (silver and gold) clay with larger, ill-sorted inclusions, most measuring <0.4mm. Although silt-sized quartz and limestone are the two most frequent constituents, additional ones vary in importance from sample to sample, with red-brown, red and brown argillaceous inclusions (metamorphic rocks and clay pellets) diagnostic. Iron-rich fragments and feldspar are also visible.

The range of inclusions present here is identical to that described for GAL AM 1. In the case of GAL AM 2, areas of the outside surface may be sprinkled or sanded with particles up to 0.7mm; even on those sherds which are not sanded, occasional larger inclusions seem to protrude the surface. However, it remains difficult to separate the two Gaulish fabrics unless a body sherd with sanding or a indicator sherd (rim, base, handle) is available.

Thin section

An exceptionally fine clay, virtually identical to GAL AM 1 is visible in thin section. It is calcareous and micaceous (muscovite and biotite), containing sparse silt-grade quartz and limestone, and even fewer opaques. A scatter of larger inclusions, measuring 0.1–0.3mm occasionally to 0.6mm, is present: primarily monocrystalline and some polycrystalline quartz and limestone, but also – in order of decreasing frequency – mica, quartz-mica schist, feldspar, ferruginous clay pellets, quartzite, quartz aggregates, fine-grained sandstone and microfossils.

Source

Although a source in Spain has been proposed (Sealey & Tyers 1989), fabric analysis indicates that despite the lack of kiln evidence at least some were produced in Gaul (Dangréaux & Desbat 1988, 123; Desbat 1987). The fabric of our samples is more in keeping with other Gaulish amphorae and this source is supported here.
