The artists who created the black-faced Mawa mask from Sabai Island [1955.251.100] and the white-faced Kosa:ya mask from the Aramia River region of Papua New Guinea were separated by 120 miles of land and water. Nevertheless, the works have much in common. Both represent ancestral male leaders. Both have relatively flat faces with pronounced noses. And both were worn by dancers during ceremonies celebrating the harvest. Native Papuans have always interacted with the islands that surround them, and these sustained exchanges have impacted every aspect of life, including the arts.
