Tahai: Its first period of construction is in the year 700 A.C. This ahu already presents several innovations, what suggests a relatively long time of local adaptation and evolution. Ariki Tuu Ko Ihu is Hotu Matua's companion who is thought as the creator of the first wooden Moai.
The Ariki would have seen two spirits that inspired him to create the Kava Kava Moai (of prominent ribs). Then, a female spirit appeared before him, and from this image he created the Pa'a Pa'a Moai.
