Moko are bronze kettledrums, whose design and decorations have their likely origin in the area around Dongson in Vietnam. While they have been found in several different locations in Indonesia, they are most famously associated with the island of Alor, where they have long been prized in ceremonial exchanges. Later moko were made in China and Java and were brought to Alor in the 19th century. However, it remains a mystery as to how the older Dongson moko arrived in Alor. Local origin stories describe the discovery of mokos buried in the ground, and it is still common to hear of moko being uncovered in this way.
Moko remain important symbols of status and are particularly important is their ritual value. Moko are still generally required as part of the bridal dowry, though the short supply of moko today means that moko must often be borrowed or mortgaged for this purpose.
