Mithras, the invincible god

Like any mythical narrative, the life of Mithras is difficult to reconstruct chronologically. No surviving text describes his deeds directly. Even so, the archaeological monuments, especially those from the Rhine and Danube provinces, provide a remarkably coherent body of imagery. Following the sequence proposed by Manfred Clauss, the story begins with the miraculous birth from the rock.

The rock-born god

Mithras is born naked, already wearing the characteristic Phrygian cap. He appears fully formed, capable from the moment of birth of fulfilling his divine mission. As he emerges from the rock, Mithras raises both arms, holding a dagger in one hand and a torch in the other. With the dagger he will perform the sacrifice that releases the forces of nature; with the torch he brings light to the world, for Mithras is genitor luminis.

Among the surviving monuments, the petrogenesis is the second most frequently represented image after the tauroctony itself, revealing the importance attached to the miraculous birth. The rock is the petra genetrix, the fertile stone and source of life. It may also be understood as a cosmic symbol, much like the cave, the sacred setting in which the central events of Mithraic mythology unfold. The rock likewise represents the Earth, an association reflected by the serpent, an animal linked to the terrestrial realm, which sometimes coils around the stone, as in the Petrogenesis from the Mithraeum I of Ptuj.

According to later tradition, the birth of the invincible god took place on 25 December and was, in some representations, attended by Cautes and Cautopates, as seen in the Petrogenesis of Mithraeum III of Ptuj.

The Water Miracle

The surviving monuments usually depict Mithras seated on a rock and aiming a bow towards a rocky wall, from which water emerges. Before him appears a kneeling figure drinking or collecting the water, while another figure may stand nearby in an attitude of supplication or with a hand placed on Mithras’ shoulder. These companions, dressed in the same oriental costume as Mithras himself, are generally identified with Cautes and Cautopates, who attend the major events of Mithras’ mythic cycle.

In this context, scholars often associate the scene with a graffito discovered in the Mithraeum of Santa Prisca, which reads: “You who have nourished the twins with nectar”.

The miracle of water is one of the great recurring motifs of ancient mythology and reflects the importance of water as a source of life. Water also played an important role in Mithraic ritual practice, as suggested by the proximity of fountains to mithraea, as well as by the cisterns and craters discovered within many sanctuaries. The crater itself, often associated with fertility and regeneration, appears frequently among Mithraic symbolic motifs.

Capturing the Sacred Bull

Mithras captures the Bull through his own strength and skill. This episode is often represented in several stages, as can be seen in the relief of Neuenheim/Heidelberg.

In the first scene, the Bull grazes peacefully in freedom. Mithras then captures the animal and carries it on his shoulders. Yet the Bull manages to escape, forcing Mithras to pursue it again. In another phase of the myth, Mithras rides the Bull while gripping one of its horns or clasping its neck with both arms.

Porphyry, in De Antro Nympharum, remarks that Mithras “rides upon the Bull”, Taurus being associated with Venus, and further notes that Mithras, “creator and lord of genesis”, occupies the region of the celestial equator.

Finally, once the Bull has been exhausted, Mithras carries it on his shoulders into the cave, where the sacrifice will take place.

The Sacrifice

The sacrifice is the central act of Mithraic mythology and appears in virtually every mithraeum. Within the cave, Mithras subdues the Bull by pressing his knee against its back while restraining its legs. He then immobilises the animal by pulling back its head and plunges the dagger into its neck.

Mithras maintains a calm and controlled attitude throughout the scene, reinforcing the idea of divine mastery. The sacrifice should not be understood merely as an act of slaughter or destruction, but rather as one of transformation and regeneration. In many representations, ears of wheat spring from the Bull’s tail and sometimes even from the wound itself.

At the moment of sacrifice, a scorpion, a serpent, and a dog approach the dying Bull, drawn by the regenerating force released through the act. The scene symbolises life reborn through death: the renewal of nature brought about by Mithras, god of light and cosmic order.

For the initiates, Mithras was the divine force that regenerated nature while simultaneously sustaining the cosmos itself. Creation emerges from the sacrifice of the Bull, a symbol often associated with cycles of death and rebirth, while Mithras, linked to the solar principle, acts as the agent of transformation.

The submission of Sol

This is one of the most enigmatic scenes found in Mithraic iconography. Sol is usually represented kneeling before Mithras in an attitude of submission. Mithras appears to place a Phrygian cap upon the head of Sol while supporting him with the other hand.

The scene may symbolise the recognition of Mithras’ superiority, while the Phrygian cap functions as a distinctive Mithraic attribute bestowed upon Sol.

The pact between Mithras and Sol

In this episode, Mithras and Sol stand face to face as equals. The two gods shake hands in a gesture known as dexiosis, often before a flaming altar that emphasises the solemnity of the moment.

For Greeks and Romans, such a gesture carried strong symbolic meaning and was associated with agreement, loyalty, and sacred bonds. In Mithraic imagery, the handshake appears to seal a pact between Mithras and Sol, possibly preceding the sacred banquet.

The sacred banquet

The surviving monuments depict Mithras and Sol reclining upon the hide of the sacrificed Bull, symbol of Mithras’ victory and of the salvation promised to his followers. Sol, often partially nude, usually appears beside Mithras, who remains dressed in his characteristic oriental garments. Both frequently raise their hands in gestures of blessing.

Other figures, dressed according to their ritual grade, stand around the divine pair and serve the banquet. In the banquet scene now preserved in the Louvre Museum, these attendants are replaced by Cautes and Cautopates.

The sacred banquet was probably echoed in ritual meals celebrated by Mithraic initiates within the mithraea.

The ascension

The mythical cycle of Mithras concludes with his ascent to the heavens alongside Sol. Both gods are represented riding the solar chariot, sometimes at the very moment Mithras mounts the vehicle with the assistance of the Sun. Sol usually drives the chariot while holding the reins and a whip.

The ascending movement is often conveyed through the inclined composition of the scene. The journey takes place across the Ocean, occasionally personified as a reclining naked figure through whom a serpent ascends as an aquatic and regenerative symbol.
