Before analyzing the next two mysteries, some background knowledge will be helpful. Archaeological objects called paenga can be found throughout Rapa Nui. These basalt curbstones once formed foundations of thatched houses called hare paenga or “boat houses”, which were so named since they looked like overturned boats. Holes in the paenga stones held poles that were tied together and then covered with thatch. A low door would be in the center of one of the longer sides of the boat house, which opened out to a stone patio. People slept “parallel to the long axis of the house, the head being towards the door; the old people were in the centre in couples, and the younger ones in the ends” [Routledge 1920, 200].

The dressed paenga stones were reused throughout the years. Sometimes new holes were made and the stones were reused for another hare paenga. Others were reused in construction projects such as ahu platforms for moai, terraces, and well linings. Paenga were even “seized upon as booty in enemy raids” [Routledge 1920, 199]. More recently, during the first half of the 20th century, when most of the island was used for sheep farming, the stones were used in the stone walls that were constructed throughout the island.

Paenga stones reused to form an oven.
