An excellent depiction of late Sassanian knights at Taghe Bostan. The figure is often identified as Khosrow II “Parviz” and his steed, Sabdiz (Picture source: Farrokh, page 225, Shadows in the Desert: Ancient Persia at War-Персы: Армия великих царей-سایه‌های صحرا).  Despite weathering and the passage of over 1400 years, the Taghe Bostan vault provides detailed representation of late Sassanian knights, notably (mail) armor and helmets.
