What form of armored heavy cavalry used in ancient warfare did Grivpanvar fought?
Grivpanvar The Grivpanvar (literally: neck-guard wearer), were an elite late Parthian and Sassanian division who fought as heavy knights or Cataphract cavalry. According to Roman sources, the Grivpanvar had the ability to impale two men on the long, heavy spears that they carried. Historical evidence suggests that the heavily armoured Parthian grivpanvar were at least partially influenced by the military of the Central Asian steppes, who in turn had inherited their armoured cavalry traditions from the Massagetae and the late Achaemenid Persians.
Serpent's Wall Serpent's Wall (Ukrainian: Змієві вали, "Zmiyevi valy" ) is an ancient system of earthen fortifications (valla) that stretch across all of Ukraine, from the town of Zmiiv in the east to Podolia in the west. They seem to be similar in purpose and character to Trajan's Wall situated immediately to the west. The remaining ancient walls have a total length of 1,000 km.
