"This place is the Sun Cave of Ancient Mithraism." The moment Leonard Ethan saw this statue, he recognized what the statue was and what it represented.
The reason why Leonard Ethan could make such a definitive decision was simple: he identified the marble statue placed in the primary position of the cave as the Mithra Slaying the Bull Statue.
This is a delicately carved and powerful statue: the Mithras, at the center of the statue, straddles a bull, his left knee pressing against the bull's waist and his right leg tightly hugging the bull's buttocks, with his right foot on the bull's hind legs.
At the same time, Mithra forcefully pulls up the bull's nostrils with his left hand, compelling the bull to lift its head. The dagger in his right hand deeply penetrates the bull's neck and kills the bull.
Surrounding this wound, strings of wheat ears burst from the wound, illustrating the miraculous part of the Mithra, as the statue intends to express.
