More than 500 years ago, Hawaiians placed four boulders on a Waikiki beach to honor visitors from the court of Tahiti’s king who had healed the sick. They were “mahu,” which in Hawaiian language and culture refers to someone with dual male and female spirit and a mixture of gender traits. The stones were neglected for many years, as Christian missionaries and other colonizing Westerners suppressed the role of mahu in Hawaiian society. At one point a bowling alley was built over the boulders. Officials restored the stones multiple times since the 1960s but informational plaques installed next to them omitted references to mahu. The stones and the history of the four healers now are featured in an exhibit at Bishop Museum in Honolulu. The display highlights the deep roots of gender fluidity in Polynesia.
