The pilgrims assembled at the foot of the mountain from the surrounding valleys. Here they were provided with food and drink by the servants of the priests. From there, two processional ways led to the sanctuary on the mountain. Both processional ways are marked with a stele close to the sanctuary. On these steles is carved a text. Here, Antiochos informs the visitors that they set foot on consecrated ground and should behave themselves as such.

The southern processional way was for the nobles of Kommagene and ended on the West Terrace. The northern was for the common people and led to the North Terrace.

At the North Terrace, in the forecourt of the sanctuary, the people were prepared for their meeting with the gods. With some difficulty you can find the worn ramp, where the people entered the North Terrace.

From there, they moved in procession to the East Terrace along the 85 metre long row of steles, which separates the North Terrace from the rest of the sanctuary. These steles bear neither portraits nor inscriptions, as Antiochos intended them for his descendants.
