Fact is that from Barthel 2 and his description and analysis of Manuscript E (a product from ca 100 years ago created by a handful of 'old ones' living at the leper station north of Hangaroa) number 70 is a key element embedded in the story about the so called explorers (scouts who mapped the island before the mythic king Hotu A Matua arrived).

 

Their voyage on the sea to Easter Island took them (according to the story) 35 days and their circuit on foot around the island had also a duration of 35 days.

 

It may be coincidence! No, definitely not. Everything meant something, anciently. It is only in the minds of our modern western society that everything is arbitrary and disconnected like confetti.
