The hook at the top represents a bird's beak, while the other rib-like structures represent the ribs of a spirit. Sometimes the hook is called 'Kamanggabi' after this spirit.Cult hooks represent spirits and are generally mounted on walls or suspended from roof beams in 'haus tambarans' (meeting huts) or spirit houses. They are adorned with items of cultural or spiritual significance. Hooks which represent powerful supernatural beings could be consulted before embarking on a raid or hunting expedition.
