In Cook Islands mythology, Tumu-te-ana-oa was the female personification of Echo.
She was the fourth child of Vari, the primordial mother goddess.
Her name means "the cause (tumu) of the call or voice (oa) heard from caves (ana)".
The term oa is used by people when calling out to evoke an echo.
Her land was Te Parae-tea, which Gill translates, "The-hollow-gray-rocks".
