Heliodromos (also spelled Heliodromus) means "sun runner" in Greek. It was one of 7 grades in the cult of Mithra. It was the 6th grade out of 7 (the 2nd highest). It seemed to refer to a runner protected by the Sun. In murals, it was depicted as a man holding a torch running (possibly analogous to the Olympic torch-bearer). Sometimes it is translated as "solar messenger", though "dromos" pertains to running.
