MARKETS, AMPHORA TRADE AND WINE INDUSTRY 239
mistakes in the following charts, I have averaged the data in timeframes of ca.
10–20 years, which in most cases represent two united chronological groups.
The chronology used in the present paper represents a combination of the
scheme in Garlan 1999a for the so-called old-style stamps, Garlan 2004 –5 for
the new-style stamps, and the corrections suggested in Tzochev 2009. The
publication schedule does not allow me to incorporate here my forthcoming
revision of the Thasian amphora stamps chronology (Tzochev forthcoming) ,
which will introduce certain corrections in the present charts, but this will
hardly alter the main conclusions.
Sales Allocation Graphs
The sales allocation charts (Figures 10.2–10. 3 ) have been compiled using the
methods described above. They offer an alternative to the methodologies dis-
cussed at the beginning of the section, being more suitable for general studies
of the trade in Thasian amphoras. As the name suggests, this type of chart gives
percentages of the total sales as allocated to different markets. The total sales
represent the entire sample of Thasian stamps, except the workshop finds (some
9,200 stamps), which were discarded as production waste and were never sent
to markets. The exports to a given site or region, divided into timeframes,
represent the percentage of the stamps recorded in this site/region from the
total of stamps for each timeframe. Thus changes of the percentages over time
indicate how the amphoras were distributed to different places.
Some comments are necessary. First, the charts are based on proxy data for
production and distribution, and they provide only estimates for trends and
proportions; their accuracy depends on factors such as sample size and chrono-
logical precision, which, at present are sufficient only for general conclusions.
Second, the term ‘sales’ may raise objections in the sense that not all amphoras
were objects of sale. Certainly, non-commercial distribution did exist (e.g.,
plunder, gift, moving of private property), but I consider stamps resulting from
such distribution to be a small part of the whole when divided among all sam-
ples.^10 They do not therefore significantly affect the proportion of the traded
amphoras. The same should be valid for the reuse of amphoras as commercial
containers in international trade, a practice that undoubtedly existed,^11 but is
not expected to alter the results, unless one can prove that certain places regu-
larly re-filled and re-exported Thasian amphoras.
One can construct sales allocation charts for particular cities or for entire
regions. Figure 10.2 illustrates the first case, using the data from some of the
biggest cities/importers of Thasian amphoras. According to the chart, in the
first half of the fourth century Panticapaeum on the northern Black Sea
coast was a major market for Thasian exports. In the second half of the cen-
tury Histria on the western Pontic coast took over this role. A trend toward
