Clibanarii
The Clibanarii or Klibanophoroi (Greek: κλιβανοφόροι, meaning "camp oven-bearers" from the Greek word κλίβανος meaning "camp oven" or "metallic furnace") were a Sassanid Persian, late Roman and Byzantine military unit of heavy armored horsemen. Similar to the cataphracti, the horsemen themselves and their horses were fully armoured. There are several theories to the origins of this name, one being that the men were literally nicknamed "camp oven bearers" (due to the amount of armour they wore that the troops heat up very quickly in the heat of battle) or that the name is derived from Persian word griwbanwar or griva-pana-bara meaning "neck-guard wearer".
The Clibanarii were used mostly by Eastern armies; for example, they were used by the Palmyrene Empire, and fought against the Roman cavalry at Immae and Emesa. Sassanids employed Clibanarii in their western armies, mainly against the Eastern Roman empire. They were more heavily armoured than their Byzantine counterparts. The Clibinarii cavalry of Shapur II is described by Greek historian Ammianus Marcellinus, a Roman staff officer who served in the army of Constantius II in Gaul and Persia, fought against the Persians under Julian the Apostate, and took part in the retreat of his successor Jovian, as:
