According to the records, the fortress of Yodong, which safeguarded the western boundaries of Goguryeo, was threatened by an invasion from the Tang dynasty of China.
The records mention that there was a temple dedicated to Jumong, or King Dongmyeong, in Yodong Fortress.
The people of Yodong believed that the armor and the spear fell from the heavens during the 4th century.
In Goguryeo society, King Dongmyeong was believed to wear a suit of chain armor and a sharp spear.
This means that he was the holy patron of the state and an ancestor deity much like Horus of Ancient Egypt.
