The wall of the main monument has a relief portraying two men forging a weapon in a smithy with a dancing figure of Ganesha, the most important Tantric deity, having a human body and the head of an elephant. In Hindu-Java mythology, the smith is thought to possess not only the skill to alter metals, but also the key to spiritual transcendence. Smiths drew their powers to forge a "kris" from the god of fire; and a smithy is considered as a shrine. Hindu-Javanese kingship was sometimes legitimated and empowered by the possession of a "kris".
