Long ago, people followed a god named Mithras.
Mithraism was a religion in the Roman Empire. It focused on a god named Mithras.
Followers met in special underground temples. These temples were called mithraea. They often looked like caves. People in the group had seven levels. They also shared special meals together. They called themselves "those united by the handshake."
Most of what we know comes from art. We do not have any of their books. One common scene shows Mithras killing a bull. This is called a tauroctony. Other art shows Mithras being born from a rock. Some art shows him sharing a meal with the sun god, Sol.
Archaeologists have found about 420 sites. They found many objects and monuments. There were likely 680 temples in the city of Rome alone. In the 4th century, the religion faced hard times. It was stopped by the end of that century.
Mithraism was a unique mystery religion in the Roman Empire. It focused on the worship of a god named Mithras. 
Followers of Mithras had a very structured way of worshiping. They used a complex system of seven grades of initiation. This means people moved through seven different levels in the faith. Members often shared communal ritual meals together. They even had a special name for themselves. They called themselves syndexioi, which means "those united by the handshake."
Because no written books from the religion survive, we rely on art. Most of our knowledge comes from reliefs and sculptures. 

Archaeologists have found many clues about this ancient world. They have discovered about 420 sites related to the cult. 

Learning about Mithraism helps us see how ancient people lived. It shows how different ideas moved across huge lands. The name Mithras likely comes from the older word mitrás. This word meant "contract" or "agreement." This connects the Roman god to older traditions in Iran and India. Scholars still debate how much of the old traditions remained. Some think it was a new god with an old name. Others see it as a single deity worshipped in many ways. It remains a fascinating puzzle for historians today.
Mithraism was a Roman mystery religion focused on the god Mithras.
The religious experience was defined by a complex system of seven grades of initiation. These grades likely represented different levels of spiritual progress or status. Members of the cult, known as syndexioi, were "those united by the handshake."
Archaeological evidence shows that Mithraism was widespread across the Roman Empire. The cult appears to have had its central hub in Rome. 
Much of our understanding of Mithraic theology comes from its unique iconography. 

The tauroctony scene is filled with specific, symbolic details. Mithras often looks over his shoulder toward the figure of Sol. A dog and a snake are frequently shown reaching toward the bull's blood. A scorpion is sometimes depicted seizing the bull's genitals. A raven may also be seen flying near the animal. In some versions, ears of wheat emerge from the bull's tail or wound. These elements suggest a deep, though debated, symbolic meaning behind the act of the bull-slaying.
Another significant iconographic element is the banquet scene. 
The origins of the name Mithras connect the Roman cult to older traditions. The name is a form of Mithra, a divinity from Iranian worship. The term likely derives from the Indo-Iranian word mitrás, meaning "contract," "agreement," or "covenant." This linguistic link is seen in the Vedic Sanskrit name Mitra. Historians debate the exact relationship between the Persian and Roman versions. Some, like John R. Hinnells, see them as a single deity worshipped across different religions. Others, like David Ulansey, believe the Roman Mithras was a new god who simply adopted an old name. This debate highlights how ideas and names traveled through the ancient world.
