The central figure is rau hei in Hb9-19. The use of rau hei - and the numbers 9, 19 - in Sunday can only be understood by reflecting on what sun is doing during the night (the week is the domain of the moon). Like the other planets he is sailing across the sky -though not on the part we can observe.

Sun must cross the sky under the earth and in a direction which is contrary to his travel during daytime. Because he must reach the horizon in the east before morning. Moe in Hb9-28 indicates the light of the morning sun before he is rising.

The nighttime canoe of the sun can be imagined in Hb9-18, a tao glyph with signs which makes it look like a vai glyph. It possibly means the beginning, the first part, of the Sunday night. Towards midnight the old day will move away to make room for next day. Manu rere has the position of the beginning of the new day. Rau hei indicates the time whan the old day will disappear, 'fall on his face'.
