Here, the Roman Emperor has taken on the guise of the mythological hero, Hercules. He has been given the attributes of the hero: the lion skin placed over his head, the club placed in his right hand, and the golden apples of Hesperides in his left. Each of these objects has been placed as a reminder of the hero's accomplishments, as well as allowing the Emperor to associate and refer to himself as the Roman Hercules. At the base of the sculpture, carved into the globe are the zodiacal signs of Taurus, Capricorn, and Scorpio. The meaning behind these symbols has been somewhat debated since the discovery of the sculpture, with interpretations ranging from purely astrological to calendric. Evidence pointing towards the latter of these two ideas has been presented by Professor Robert Hannah of The University of Waikato, who has pointed to the thought that these signs could represent the month of October, which the emperor had renamed after Hercules during his rule:
In this way, the signs are interpreted as an indication of the month of October. October figured prominently at various stages of Commodus' life, and indeed was renamed after Hercules by the Emperor. This calendric interpretation can therefore be seen to emphasize the Herculean aspect of the portrait.
Other sources argue that the three signs instead are linked to the foundations of the city ofRome. In this case, Taurus represents the founding of Rome under Romulus, which took place traditionally on the 21st of April, Capricorn represents Augustus, who regarded the sign as his, and finally Scorpio would represent the Emperor himself, as the third "founder" of the city. This popular theory also can be seen as Commodus once more emphasizing his association with Hercules, as Scorpio would fall into the month of October, which he had renamed after Hercules. Further decoration can be found surrounding the globe, from the kneeling Amazons to either side, to the cornucopia entangled with a pelta. Believed to be for the purpose of celebration, this idea is furthered by the inclusion of two Tritons, which are believed to represent his apotheosis.
Intent
There is speculation of the Emperor's intent by creating depictions of himself as a godlike figure. While some sources say it was Commodus's desire not to be the protege of Hercules, but to be a god, the incarnation, the epiphany of Hercules and others claim instead that he simply desired to be the center of attention and show his intense appreciation for games and spectacles. Archaeologist and museum directorMortimer Wheeler suggested that although the bust would have been made for Commodus or someone close to him at the court, and the mythological topic decided by the patron, the artist was deliberately subverting the flattering subject and casting the flamboyant emperor in an ironic light: the contrast between the trappings of Hercules, the real hero, and the "effeminate" and self-obsessed emperor shown in stone here is too grotesque to be taken only as an idolizing portrait, and the hidden intention becomes ironic. "The sculptor must have felt very sure of his ground, protected by the blind vanity of his sitter".
