Changes in 5th Century Cavalry Scale Armor

The armor for Cavalry in the 5th century consists of body armor and accessory armor that protects the neck and shoulders. Among them, the armor that protects the body consists of Dongchal, Yochal, and Sangchal, of which Yochal is the most morphologically specific and easy to distinguish. It was revealed that the change of Yochal has been transformed into an S-shape → U-shape → Omega-shape through the excavation and research of armor. In 2024, the Gyeongju National Research Institute of Cultural Heritage reported the excavation of the C10 from the Gyeongju Jeoksam C10 through 『Ⅹ V of the Silla Ancient Tombs in Jeoksam District』. This is the only case in Korea in which a complete body of stone has been excavated. The complete set was excavated by integrating the helmet, body armor, accessory armor, and Horse armor. The shape of the Yochal and Quantity are unique. The Yochal of Scale armor in Gyeongju Jeoksam C10 are made up of two tiers. And the number of small Scales of Chalgap is close to 1,000. Although the number of Scales pieces is overwhelmingly large compared to the previous excavation of Scasle armor, there have been no cases in which multiple pieces of Scasle armor were buried in Gyeongju, and about 1,620 pieces of Scales armor in Kinai Higashiura Excavation in Gunma are made up of one piece of Scales armor in Gyeongju Jeoksam C10. Additionally, it is assumed that the two-tiered U-shape of the Scales armor discovered in Gyeongju's C10 is related to the increase in the number of inspections, although it was previously thought that Scales armor consisted of one stage. It is presumed that the change in Scales armor is related to the increase in the quantity of Scales after the end of the 5th century, given that the area of Scale armor's Yochal, which uses the existing S-shaped Yochal, is larger than that of Scale armor, which uses the U-shaped Yochal, and that the number of Yochal since the end of the 5th century appears to be large Obviously. In addition, the incontinence was necessarily made of iron and used, which seems to be to add curvature to the cross section. The need for a cross section of the incontinence seems to play a role in preventing the lower end of the incontinence from stabbing the occupant in the pelvis or thigh when he sits in the saddle. This means that the armor with the incontinence was made with the assumption of horseback riding. However, there is a problem that the pattern of changing from a U-shaped incontinence to an omega-type incontinence cannot be explained through the quantification of the incontinence.
