The purpose of this study was to know how helmet and armor was reinterpreted in historical
play by considering general concept and type of old helmet and armor from the aspect of costume
history and comparing the helmet and armor types of TV historical plays, Yeongaesomun and
Taewangsasingi, whose historical backgrounds were based on the age of Goguryeo. The helmet and
armor type shown in Yeongaesomun was reinterpreted as the one, which is close to historical investigation,
by reappearing lamellar armor and jongjangpanju(helmet made of slim, long plate)
shown in Goguryeo wall painting. The helmet and armor type shown in Taewangsasingi expresses
fantastic helmet and armor by adding fantastic factor regardless of historical investigation. The
study result reveals that there are several common characteristic factors between the helmet and armors
of two historical plays. First, there was a classification in the display of character and story.
The helmet and armor type shown in Yeongaesomun classified color and detail design depending
on lamellar armor or character. In Taewangsasingi, the helmet and armor was manufactured depending
on character's nature and the chain armors, which are lighter than existing helmet and armors,
were usual. Second, they escaped from the historical investigation about traditional helmet
and armor. In Yeongaesomun, myeonggwangae(a type of armor), which might be popular, was not
expressed and Taewangsasingi is free from an imperative idea of historical investigation by manufacturing
helmet and armor referring to that of ancient Rome age. The modern sense was reflected
to increase dramatic effect. The helmet and armor of Yeongaesomun provides modern feeling by
using stainless steel material and modern color arrangement and that of Taewangsasingi is designed
in modern, splendid way as it aimed at game development from the planning step.
