Upper tier The enthroned figure, #1 in the numbered illustration, is usually taken to be Augustus, although in some interpretations, it could represent a later Roman ruler. Figure #1 is holding the augur's staff, known as a
lituus, a symbol of military high command. Figure #3 is the most readily identifiable, having characteristics held by no other. The woman is
Oikoumene - the personification of the inhabited world. This inhabited or civilized world is either that of the early
Roman Empire, or more likely the
Mediterranean world conquered by
Alexander the Great. She wears upon her head a
mural crown and
veil. She is crowning figure #1 with the
corona civica of
oak leaves - used to commend someone for saving the life of a Roman citizen. In this grand scale depiction, however, it is given to figure #1 because he saved a multitude of Roman citizens. Figure #5 and #6 seem to be closely related. Figure #5 is
Oceanus or
Neptune whose significance is often seen as one balancing the scene across from #4 and #7, and also an important onlooker, as he represents the realm of water. Below him is a reclined personification of either
Gaia or
Italia Turrita (#6). The scholars who see Gaia link her with the
cornucopia and the children surrounding her, who may represent seasons. It might be odd that Gaia holds the horn of plenty when it seems as if the horn is not presently producing anything. This supports an argument that she is not Gaia, but Italia, for historically there was famine at the scene's event. Also, she wears a
bulla, a locket of some sort, around her neck, which, again, would seem odd for Gaia to wear. Either way, the children represent seasons, probably summer and Autumn, as one of them carries grains. Figure #10 is the
eagle of
Jupiter. The eagle could be showing that figure #1 is seated in the role of Jupiter. Seated next to figure #1 is
Roma. The helmeted goddess holds a spear in her right arm while her left hand lightly touches the hilt of her sword, probably showing that Rome was always prepared for war. Besides showing her feet resting upon the armor of the conquered, Roma seems to look admiringly towards figure #1. Though there might be a dispute as to who #1 is, it is often said that the image of Roma strongly resembles
Livia, Augustus’ long-lived wife. Not only was she his wife, but from a previous marriage, the mother of
Tiberius. The reason for the cutting of this gem is also called into question when it is noted that Roma was not worshiped inside Rome till around the rule of
Hadrian. Thus the gem might have been custom cut for a friend in the provinces. Figure #4 is
Victoria driving the
chariot that holds the descending figure #7. She is obviously the deliverer of the victorious but not necessarily there for celebration, as it seems she might be impatiently urging figure #7 on to his next campaign. In associating Victoria with the
chariot, it is necessary to analyze some historical importance relating to the chariot and the horses around it. The two
foreshortened horses in front of the chariot are part of the chariot team, whereas the single horse to the side cannot be, and might belong to figure #8. Historically, a victory chariot was driven by four horses forming a
quadriga, not the mere two represented on the gemma, a
biga. This might show that figure #7 is not a
triumphator.
Lower tier: erection of tropaion from reign of Emperor
Marcus Aurelius, AD 161–180. The lower scene, in which the figures are less readily identifiable, depicts the erection of a
tropaion. In some interpretations of the scene, all the lower figures are by design anonymous. Other interpretations attribute definite real or mythological persons to the figures. At left, the seated male and female figures (combined in #11) are either
Celts or Germans, as is apparent from their clothing and hair styles, including the man's beard, and represent prisoners of war, symbolizing the Roman victory. The man is bound with his hands behind his back, and both are apparently about to be tied to the base of the as yet half-erected
tropaion (figure #19), a trophy of war displayed upon winning a battle, usually fixed into the ground at the position of the "turning-point" of the battle in favour of the victors. The trophy consists of a wooden cross, designed to support human clothing. A helmet is placed on top, and the breastplate and weaponry of the enemy is placed upon it. In the scene, four young men are raising the trophy into a vertical position. Figure #18 is the least identifiable, but his helmet has led some to believe that he may be a
Macedonian soldier of King
Rhoemetalces I, who helped Tiberius in
Pannonia. Figure #15 is often identified as a personification of the god
Mars with his armor and flowing cape. Although figures #16 and #17 seem less important, they look very much alike and may represent the
constellation Gemini. Gemini is the more difficult constellation to pick out, and it might represent the hidden identity of figure #8. Two others, however, are more obvious. Figure #20 is a shield with a large
scorpion emblazoned upon it. Tiberius was born in November, and thus might be represented with such an item. Figure #9 shows Augustus’ favorite sign, the
Capricorn. Although Augustus might have been conceived during December, he claimed the Capricorn as his constellation. The sun or moon, which were necessary to show the full power of a constellation, is seen behind the sign. Mars is represented by figure (#15), and thus at least three signs of the
Zodiac are evident. Figure #13 is probably Diana, identified with the moon, although some commentators believe her to be a mere auxiliary troop with #14. Diana holds spears in her left hand and her right hand seems to rest on the head of the man in figure #12, but not gripping his hair as supposed by many. Another identifying feature of Diana is her bountiful hair, bound up for the hunt, and her hunting clothes. Figure #14 might be an auxiliary, but more likely he personifies Mercurius (Mercury/
Hermes), identified by his rimmed hat. Mercurius seems to be dragging the female in figure #12 by her hair towards the
tropaion. The scene is clearly complex. Many interpretations insist that the ‘auxiliaries’ are dragging the barbarian prisoners to join their kindred in being bound to the trophy. However, there are indications that this might not be the case at all. First, the man on his knees is begging for mercy from Diana, who does look down on him. That same man wears around his neck a
torque, suggesting him to be a Celt or German. It may be significant that Diana has her back turned to the observer and possibly the scene itself. She is the only one as such, and perhaps to contrast the celebration of victory in battle, she shows instead mercy to one pleading for his life. In addition, since the man is a leader, it makes for better propaganda that he should beg for mercy before a Roman goddess. Mercurius might not be dragging the woman to be bound to the trophy, but might be bringing her to kneel before Diana to beg for mercy as well. She shows the sign of a truce by placing her hand upon her chest. Perhaps Diana and Mercurius are sheltering them, perhaps offering them salvation in the final moments of victory. Whatever the case, the couple in #12 are not comparable to the despairing couple in #11, with whom they appear both to balance and contrast; balance by having barbarians on the right and left, literally balancing the composition, and contrast as one couple being doomed to be bound at the trophy, and the other begging for what looks like a chance of mercy. == Overall scene ==
