The coins

On the total majority of royal coins issued during the sole reign of Antiochos VIII,¹ either the epithet Epiphanes (“Illustrious” or “[God] Manifest”) is attached to his name or his name is stated without any epithet. His coins therefore bear either the inscription ‘ΒΑΣΙΛΕΩΣ ΑΝΤΙΟΧΟΥ ΕΠΙΦΑΝΟΥΣ’ or simply ‘ΒΑΣΙΛΕΩΣ ΑΝΤΙΟΧΟΥ’.² There is only one exception, a small issue of bronze coins minted at Antioch on the Orontes which bear the epithet Philometor (“Mother-loving”):³

This small issue is a part of an extensive series of bronze coins which was minted at Antioch mint from 121/0 BC (SE 192) to 111/10 BC (SE 202). Coins of this series have the same design as the coins with the epithet Philometor, but they bear the standard epithet Epiphanes and they are dated SE 192, ... , SE 200 and SE 202 (coins of this series dated SE 201 are not known).⁵ Whereas coins of this series with the epithet Epiphanes are abundant, the coins bearing the epithet Philometor are rare and they are known from the year SE 202 only. Moreover, this epithet is not found elsewhere on Antiochos VIII’s coins.

Note that the epithet Philometor in itself is strange considering the role of Antiochos VIII in the death of his mother, Kleopatra Thea:⁶

Justin, Epitome of the Philippic History of Pompeius Trogus, 39.2: Grypus (Antiochos VIII), having thus recovered his father’s throne, and being freed from foreign perils, found his life endangered by a plot of his own mother (Kleopatra Thea); who, after betraying, from desire of power, her husband Demetrius (Demetrios II), and putting to death her other son (Seleukos V, the oldest son of Demetrios II), was discontented at her dignity being eclipsed by the victory of Grypus, and presented him with a cup of poison as he was returning home from taking exercise. But Grypus, having received notice of her treacherous intention, desired her (as if to show as much respect for his mother as she showed for him) to drink herself first, and, when she refused, pressed her earnestly, and at last, producing his informant, charged her with the fact, telling her, “that the only way left to clear herself from guilt, was, that she should drink what she had offered to her son.” The queen, being thus disconcerted, and her wickedness turned upon herself, was killed with the poison which she had prepared for another.

Appian, Roman History, 11.69: After Seleucus (Seleukos V, the oldest son of Demetrios II), Grypus (Antiochos VIII) became king, and he compelled his mother (Kleopatra Thea) to drink poison that she had mixed for himself. So justice overtook her at last.

However, as Houghton, Lorber and Hoover mention in SC II (Vol. 1, p. 502), this epithet was born apparently without any irony. It is also attested by Eusebius of Caesarea⁷ and by an inscription from Delos (ibid, p. 487).

List of known specimens

The following table shows all specimens known to me.⁸ Please contact me at pvesely2002@yahoo.co.uk if you are aware of other coins of this type.

The abbreviations A and P stand for Anvil (obverse) and Punch (reverse) dies but the die identification is tentative because details are not clearly visible on some coins.

Die analysis

Die frequencies are presented in Table 1. The 13 coins catalogued here were struck from 7 obverse and 11 reverse dies. Three obverse dies are represented by one coin (A2, A6 and A7), two obverse dies are represented by two coins (A3 and A5) and the remaining two obverse dies are represented by three coins (A1 and A4). Two reverse dies are represented by two coins (P4 and P8) and the remaining 9 reverse dies are represented by one coin.

Table 1: Die frequencies (numbers of dies represented exactly N times)

Note that all coins have bevelled edges. In six cases (coins Nos. 2-3 and 6-9) the smaller face of the bevelled edge blank was struck with the obverse type. In seven cases (coins Nos. 1, 4-5 and 10-13) the smaller face of the bevelled edge blank was struck with the reverse type. Obviously, the mint did not pay attention to which face of the single bevelled edge blank received which type.

For completeness, estimates of coverages of the corpus¹⁰ and of original numbers of dies are presented in Table 2.¹¹ Nevertheless, it is necessary to emphasize that these estimates are statistically dubious and they should be taken extremely cautiously because the number of coins is very small and because the die identification is tentative (details are not clearly visible on some coins).¹²

Table 2: Estimates of the coverage and of the original number of dies

To receive more reliable results, it is necessary, on the one hand, to enlarge the corpus and, on the other hand, to accumulate a representative corpus of the common variant with the epithet Epiphanes and to put the examined variant with the epithet Philometor into context from the point of view of obverse die links and from the point of view of annual production of the common variant. Such widening of this study is being prepared.

Weight analysis

Table 3 shows statistical characteristics of weights of coins in the corpus.¹³ Figure 1 shows a histogram of weights of coins in the corpus with a kernel density estimation¹⁴ and the fitted normal density curve superimposed (plotted against the right vertical axis). The normal probability plot is shown in Figure 2. The normality assumption does not seem to be seriously violated.¹⁵

² The short inscription ‘ΒΑΣΙΛΕΩΣ ΑΝΤΙΟΧΟΥ’ is abbreviated as ‘ΒΑΣΙ ΑΝΤΙ’ or ‘ΒΑΣΙ ΑΝΤΙΟ’ on some quasi-municipal bronze coins of Laodikeia in Phoenicia (Berytos). See Houghton, Lorber and Hoover, SC II, 2327 and 2328.

³ Houghton, Lorber and Hoover, SC II, 2308

⁴ Houghton, Lorber and Hoover, SC II, 2308, mention a cornucopiae in exergue, on right, and they refer to a coin in the Hunterian Collection (MacDonald, Catalogue of Greek Coins in the Hunterian Collection, Vol. 3, p. 103, No. 39, Plate LXX, 2) which is presented as coin No. 2 in the list of known specimens on this webpage. However, it is not clear if the cornucopiae is really present in the exergue of this coin. Note that this coin is mistakenly described as having a cornucopiae on left by MacDonald.

⁵ Houghton, Lorber and Hoover, SC II, 2300 and 2307

⁶ For biographical data on Kleopatra Thea, see the page devoted to her genealogy.

⁷ Eusebius, Chronicle, pp. 259-260: He (Antiochos VIII) was given the names Grypus (“Hook-nose”) and Philometor.

⁸ My sincere thanks to the Hunterian Museum and Art Gallery (University of Glasgow), to Tom Kirby, to Daniel Kearney, to Classical Numismatic Group, Inc., and to Münzen & Medaillen GmbH for photos of their coins and for their kind permissions to publish them on this webpage.

⁹ MacDonald, Hunterian Coll. III, p. 103, mentions a cornucopiae in the left field. It is not clear if there is such a symbol on the reverse. See footnote 4.

¹⁰ The coverage is the fraction of all produced coins of the given type that are from dies represented in the corpus. That is, the coverage is the fraction M/N where M is the number of all coins originally struck by the dies that are observed in the sample and N is the number of all produced coins of the studied type.

In other words, provided that the corpus can be considered a random sample from all produced coins of the studied type, the coverage of the corpus is the probability that a new coin of that type will be from a die already recorded in the corpus. It means that 1 minus the coverage is the probability that a new coin would yield a new die. Let us emphasize that the coverage is a property of the corpus, not of the coinage issue.

¹¹ The coverages were estimated via Good’s coverage estimator, see Esty 1986, formula J2 (p. 208). For small random samples, this formula is slightly preferable to formula (1) presented in Esty 2006, p. 359 (see Esty 1986, formulas J1 and J2 and the following discussion). The confidence intervals were computed according to Esty 1986, formula J3 (p. 208), which is the same as formula (5) in Esty 2006, p. 360. Note that this formula works well for the sample size at least 30 or more (Esty 2006, p. 362) whereas our sample is much smaller.

The original numbers of dies were estimated according to Esty 1986, formula H5 (p. 205) where the equal-output estimate k' was computed by formula K1 (p. 209). The so-called shape parameter p was set to 2 (see Esty and Carter 1991-2). This is equivalent to Esty 2006, formula (2). Formula C2 in Esty 1986 (p. 201) was used for computation of the confidence intervals (formula (4) in Esty 2006 is a simplified version of the formula C2).

Note that Esty’s formula gives the left end of the 95 percent confidence interval for the number of obverse dies equal to 6 which is less than the number of obverse dies in the corpus (7 dies). For this reason, the left end of the confidence interval was set to the number of obverse dies in the corpus.

¹² There is still another potential distortion. It is likely that there are obverse die links with Antiochos VIII’s coins bearing the regular epithet Epiphanes on the reverse (for coins of this type dated SE 202, see, e.g., Houghton, Lorber and Hoover, SC II, 2307.2). It means that numbers of coins with the epithet Philometor assigned to such dies are lower than the total production from these obverse dies. This kind of censored data may somewhat distort the estimates of the original number of obverse dies.

¹³ The unbiased estimate of the standard deviation was used (i.e. the number of observations minus one was used as a divisor).

¹⁴ Gaussian kernel was used with the bandwidths given by equation (3.31) of Silverman 1993, p. 48.

¹⁵ Lilliefors test also does not reject the assumption of normality of data (p-value of 0.357).
