 Professor Woo-bang Kang has argued that the statue was made in Goguryeo, who he believes was the only state technologically capable of casting the image, and was at one point brought to the south.National Treasure no.78 could also be a Baekje image because the Baekje kingdom probably had sufficient casting expertise by the late 6th century and several bodhisattva images associated with Baekje, particularly one in the collection of the Tokyo National Museum (image), bear stylistic resemblances to the treasure.
