This large ceremonial adze from Mangaia, Cook Islands, is a striking example of the island's distinctive ritual craftsmanship. The underside of the blade bears a historic paper label with a faded black ink inscription, partially struck through with blue chalk, reading "Mangaia. [?] Eykym [or Eykyn] T. Eykym [or Eykyn] 1840," offering a rare glimpse into its early 19th-century provenance. This inscription suggests the piece was documented or acquired around 1840, lending it both cultural and historical significance as an artifact of Mangaian ceremonial tradition.
