"The 'Staff' is the only original incised kouhau - Old Rapanui for 'staff' - that survives. It is manifestly the sole remnant of a whole group of documents that evidently in 1864 were still as numerous as the incised tablets."

"My own investigations ... have identified as the text's first line Philippi's / Barthel's line 12 - the three-quarter line that commences with an exceptional half-sized glyph some 35 cm in from the thin end of the 'Staff'. This is just below the point where the thumb of a c. 190 cm-tall, right-handed man would touch the artefact whose thick end is resting on the ground, next to the instep of the left foot, tilted diagonally to the left (as deduced from this end's damage and from the position that is most comfortable for the bearer of this heavy artefact)."

Twirling the staff 180^o around its long axis and held with the left hand (diagonally with the thick end towards the instep of the right foot) would suit a righthanded person better I think. The right hand should be free for gesticulating when performing.
