Mamuli are ornate metal ornaments crafted by the Sumba people of Sumba, Indonesia. These pieces are particularly important in the megalithic societies of western Sumba, such as the Anakalang society. The distinctive shape of Mamuli symbolizes the female genitalia, representing fertility and the role of women as life-givers. Mamuli are highly valued as heirloom pieces, playing a significant role in ritualistic exchanges during important ceremonies. Mamuli can either be simple (lobu) or decorated (karagat). The lobu mamuli typically have a diamond-shaped body with a concave center, featuring a round hole and vertical slit symbolizing female sexuality and reproductive power. In contrast, the more ornate karagat mamuli, also referred to as ma pawisi ("those with feet"), have additional finials at the base of the diamond shape, often giving them an omega-like appearance. These finials are typically adorned with figures such as roosters, cockatoos, horsemen, buffalo, goats, skull trees, or warriors, representing male power and greatness. Hence, the karagat mamuli are viewed as masculine, while the lobu mamuli are considered feminine. During the colonial period, more elaborate, Baroque-inspired Mamuli were created, featuring complex battle scenes and sometimes movable parts.
