Pair of Brass Aso Pendant Ear Ornaments, Kenyah/Kayan Dayak People, Sarawak, Borneo, 19th century


Pair of Solid Brass ‘Aso‘ Pendant Ear Ornaments

Kenyah/Kayan Dayak People, Sarawak, Borneo, Malaysia

early 20th century

length: 7cm, width: 4.5cm, combined weight: 106g

This pair of man’s brass ear ornaments were used as decorative weights to stretch the ear lobes to exaggerated lengths. (Women tended to stretch their ear lobes much more than men: it was considered effeminate for a Dayak man to have lobes stretched beyond the shoulders. Today, the practice of elongating the earlobes has largely died out among the Dayaks.)

The form of these ear pendants is based on the

aso, a mythical underworld hybrid dragon-dog female fertility figure. Richter (2000, p. 174) says that such ‘curvilinear vitality’ may be derived in part from dragons or other mythical creatures portrayed in Chinese trade ceramics that were imported into Borneo in vast quantities.

Each of the pair has been made separately, using the lost-wax casting method. Each time an item is cast using this method, the cast must be broken and made from scratch, hence the two are not, indeed, cannot be identical.

Ear ornaments of brass were signs of prestige and beauty. This pair would have been reserved for a more powerful and prestigious wearer.

Related examples are illustrated in Rodgers (1995, p. 279).

The pair is in fine condition. There are no repairs or any other condition issues. They have a light chocolate-brown colouring and have been worn smooth by years of handling.
