THE DEGREE OF ECONOMIC INTERPLAY 279
reasons
for
such choices and changes of standard will be in part explored
below,
but
some notion
of
their effect needs
to
be formulated
at
once.
It
is often said that
the
effect
of the
adoption
or
retention
of
particular
standards
was to
create economic isolation
or
a
'closed economy'.
122
Such statements
are
at
best fierce oversimplifications.
By
that token
Rhodes, with a standard shared
by few
mints save Chios and Cos
in the
third century, should have suffered thereby, which hardly appears
to
have been the case: understandably,
for
nothing intrinsically precluded
the free convertibility
of
different currencies when weighed
as
the
bullion which (as reasonably pure silver) they all basically comprised.
123
That
is not to
deny
the
existence
of
'closed economies',
at
least
in the
sense that (e.g.) Ptolemaic coins barely appear in Seleucid areas or indeed
outside the Ptolemaic monetary zone of Cyrene, Cyprus and Syria, while
Seleucid
and
other foreign coins
do not
appear
in
Egyptian hoards.
124
However,
the
creation
and
continuance
of
such exclusions
is
not
a
matter
of
standard
but of
the degree
of
informal willingness
to
accept
foreign coin,
of
the reliability
and
frequency
(or
otherwise)
of
facilities
for exchange,
and
above
all of
the
presence
or
absence
of
legal
prohibitions created
by
fiscal policy.
A second factor
is the
need
to
identify
the
routes
and
mechanisms
which yielded
the
distribution
of
coins attested
by
hoard
and
other
evidence and now increasingly becoming the object
of
detailed study.
125
At least five major mechanisms
can be
isolated:
(i) the
payment
of
military forces, especially
but by no
means only
of
mercenaries;
126
(ii)
moneys paid by the kings as subsidies to cities in difficulty,
127
as bribes
to
122
E.g. Will 1979, 178: (A 67), and Preaux 1978,
1.248:
(A 48),
for
the Ptolemies; Seyrig 1963,
2zff.:
(B 261), and 1968,
190-1:
(B 262),
for
cistophori.
123
It is
pertinent
that
many hoards
contain
silver
as
money
and
silver
as
plate
buried
together,
the
ensemble
being
evaluable
only
by
weight.

Any bibliography
of
this work can only

Some major recent
studies
of
Hellenistic hoards are Wallace 1956: (B 274), M. Thompson 1968: (B 271), and Seyrig
1973: (B
263). The circulation of coins of certain mints
or
regions has been studied, by
inter
alios,
de
Laix 1973: (B 235) (Aetolia); Hackens 1969: (B 228) (Boeotia); Shelov 1978: (B 264) (Bosphorus);
Seyrig 1963: (B 261) and Schonert-Geiss 1970: (B 260) (Byzantium); Picard 1979,
3O7ff.:
(B 252)
(Chalcis); Le Rider 1966:
(B
237) (Crete); Hackens in Bruneau and others 1970, 3876".:

Dunant
and
Pouilloux 1958,

(H 53) (Thasos); Robert 1951, 69-100
and
243-5: (B 253),
Bellinger 1961:
(B
215), and Robert 1966, 94-114:
(B
254) (cities
of
Troad). Not all
of
these studies
pay equal attention to the two sorts of distribution map or survey required, (a) that of the find-spots
of the coins of
a
given mint or city, and (b) that of the mints or cities of origin of the coins found in
one area
(for the
distinction

Robert 1954,

(E 94)). Exemplary
are
Dunant and
Pouilloux 1958: (H 53) and Picard 1979: (B 252).
