 Occasionally single mandorla triads were made with the bodhisattva as the main figure with two monks as attendants.The stiffness of early Goguryeo sculpture is sometimes attributed to the harsh climate of the kingdom which was situated in northern Korea and Manchuria.The replacement of the typically elongated and lean face of Goguryeo sculpture, exemplified by the Yŏn'ga Buddha and the Standing Bodhisattva with triple head ornament shown below, with images with plump faces and gently depicted robes, exemplified by the Wono-ri Bodhisattva, may reflect the conquering of the Han River valley from Baekje in 475 or the introduction of gentler climes.
