No Kaʻahupahau is a mixed media series of visual studies created by Herman Piʻikea Clark as part of a collaborative design proposal for the Waiawa train station on Oʻahu. These works reflect Clark’s signature approach to Indigenous abstraction, where ancestral figures, natural elements, and cultural symbolism are distilled into rhythmic, contemporary forms. The series honors Kaʻahupahau, the shark goddess and protector of Puʻuloa (Pearl Harbor), whose presence remains vital in the cultural memory of the surrounding landscape. Rather than represent her directly, Clark engaged with the moʻolelo through abstraction—working with pattern, texture, and spatial rhythm to suggest her movement, guardianship, and enduring mana. The use of layered materials and interwoven motifs speaks to the complexity of place-based identity and the ways ancestral knowledge is embedded in land and water. These studies were conceived not only as aesthetic compositions, but as conceptual groundwork for large-scale, site-specific public art—works intended to restore cultural presence within modern infrastructure. No Kaʻahupahau continues Clark’s broader commitment to integrating Indigenous design principles into public space, inviting both recognition and reflection through abstraction.
