Illustration 47. The augmented series of issues (excluding
the bronze type already
illustrated in fig. 44) of king Aphilas; three types of gold (d. c. 16mm, 12mm, and c.
7mm respectively), two of silver (d. 17mm and c. 12mm), and two of bronze (d. 18mm
and c. 15mm).
Aphilas also instituted some less successful experiments. His quarter-aureus is only
known from one specimen, and he also issued considerable numbers of very tiny gold
coins whose weight seems to indicate one-sixth of the aureus. The weights of the
surviving specimens are often, as might be expected, a little down on the theoretical
weight; this is one of the means by which a coinage can be very profitable to an issuing
authority. However, the Aksumites were reasonably careful over their gold weights, and
sometimes a coin is found which is even a little over the theoretical weight. Perhaps due
to archaeological
accident at this stage, since very few coins have been available for
analysis, but later very deliberately employed, is the very slight debasement with silver
from the standard set by Endubis; the lowest gold content so far recorded for Aphilas has
sunk to 90% (Oddy and Munro-Hay 1980; Munro-Hay, Oddy and Cowell 1988). The
constant decline of the gold content, slow as it was at first, must eventually have been a
severe blow to the credibility of the Aksumite coinage, and would have set it at a
disadvantage
against the Roman gold, which was of very high purity and very reliable.
A shifting inter-relationship of value with the Roman gold may have been the reason why
the Aksumites retained the heavier `tremissis' of c. 1.60g when the Romans reduced the
weight of their tremissis to the true third of a solidus, with a theoretical weight of about
1.51g under Theodosius I in c383. Only right at the end of the series, with Iathlia (=
Hataz?) and Gersem are lesser weight coins issued, whilst Ella Gabaz, in the sixth
century, issued some unusually heavy specimens. Weight variations could have emerged
from a mint practice of striking a given number of coins from a given amount of metal —
from Roman examples the weight of each individual coin could thus vary considerably,
even at its emergence from the mint in pristine state. The element of seignorage,
the mint
profit, or at least coverage of expenses, could be arranged by the retention of a small part
per pound of metal — this has a corollary in as much as it would help to guard the
coinage from destruction since each coin would represent a theoretical purchasing power
slightly in excess of its real value, fractionally reduced vis-à-vis the correct proportion of
the pound of gold.
To return to Aphilas' innovations, it is apparent that, although the experimental fractions
died out with him as far as the gold was concerned, he also experimented with fractions
of silver and bronze. The silver half which he issued was
retained as the norm for Aksum,
the heavier silver being discontinued in the next reign or two. Presumably, the value it
represented was too high for a single coin in the particular market situations to which it
was exposed, and the half was instituted as a more convenient weight; Aphilas did the
opposite with his bronze, issuing a very heavy (presumably double) type, weighing 4.83g
in the only known specimen. Like the quarter-aureus, it may have been soon withdrawn,
resulting in its rarity today. Interestingly enough, both of these issues showed the king
from a frontal position (as also on one of his normal weight bronze issues), a style
abandoned afterwards
until the sixth century, and used only by Gersem on the gold, as
noted above.
The designs on Aphilas' issues introduced two other features, which also did not last
long. The tiny gold fraction had nothing on the reverse but the words `kin(g) Aphilas', the
only time a purely epigraphic reverse appears in the entire series. On one of his bronze
issues, he placed the ear of wheat alone in the centre. Only Ezana(s), in a pre-Christian
issue, copied this design, which then died out.
All these innovatory issues were doubtless efforts by Aphilas to speed up acceptance of
the use of the coinage within his kingdom, and to develop its use for trade, as well as to
raise his own international prestige by the advertising medium which the coinage offered.
Aphilas seems to have made further considerable efforts to encourage the use of his
smaller silver fraction by recourse to a completely unique expedient.
On the reverse of
the coin, around the royal bust, the whole area delineated by the circle outside which the
legend ran was covered with a thin layer of gilding. The result was both attractive,
showing the king in a halo of gold, and impressive; it showed the wealth of the king of
Aksum in an inescapable fashion. The work must have been costly, as well as difficult to
execute, and indicates how earnestly the mint authorities viewed the need to impress a
people unused to coinage with its real value. Whether the half- value silver coins were
deliberately under-weight to counteract the value of the added gold is unproven, but very
likely, since the heaviest surviving examples of Aphilas' silver
gilt issue weigh less than
half of the lightest surviving specimens of the heavier issue without gilding.
Aksum seems to have had considerable supplies of gold available for its coinage. As the
number of coins available for study increases, it is becoming evident that numerous dies
were employed. Although we cannot even estimate the numbers of coins which could
have been struck from a single die before it became too worn for further use, it is evident
that certain rulers at least issued gold pieces in impressive quantities.
The rulers who succeeded Aphilas, as well as abandoning gold fractions, appear to have
slowly and very slightly reduced the weight of their half-aurei, but to have more or less
retained the level of purity of the gold. Perhaps the Aksumite sovereigns were trying to
adjust their coinage to agree with the reform of the Roman monetary system from 1/60th
of a pound of gold (5.45g) to 1/72nd of a pound before 312AD.
The theoretical weight
would have been 2.27g for the Aksumite issues.
Wazeba, very possibly Aphilas' successor for a brief time only (one gold coin is known,
and not too many silver), altered, for the first and only time on the gold issues, the
language of the legend. His Ge`ez legend, and the monogram of South Arabian style
which he employs on the same coin, make one think that perhaps he aimed his gold
coinage more towards Ethiopian users, and also possibly to those South Arabian regions
which some of his successors claimed as part of their kingdom. After Wazeba, the use of
Greek remained permanent for the gold, but gradually,
starting with Mehadeyis
(MHDYS) for the bronze and with Wazeba himself for the silver, the native language
came to supersede the Greek, doubtless a reflection of its local circulation area. Greek,
however, still remained prominent on silver and bronze throughout the fifth and into the
sixth centuries.
