Sesako decorates the back of a throne, which is customarily used by the Penyimbang (tribal head) of a society, following pepadon (traditional) customs. It is required for the performance of inauguration rituals to officially appoint a tribal head who, during the ceremony, as a ‘would be chief’, will sit on a low stool, waiting to formally receive his new position of power.
The sesako's main motif is a Kālamakara, depicting at its center the head of a man, flanked by curling dragons on either side. These dragons are a motif of power, similar to what has been found in 8th and 9th century Hindu Temples, on the island of Java. According to local beliefs, the pepadon chair is the home of a magical, mystical snake, able to warn its owner, if somebody is harboring evil intentions towards him.
