Some of Wilkinson's comments upon the Egyptian 'GD24':

"As the sun was the 'eye' (*D10) of the sky god Horus or Ra, it often was represented as a disc on top of the head of a falcon or as a winged disc (*H5).

But there were many other gods who were identified with the sun: morning, noon respectively evening sun were associated with the winged scarab Chepri (*L1), the great god Ra, and with Chnum the god with a ram's head (*E10).

During the Late Period different manifestations were associated with every hour of the day and the sun was represented in twelve different ways, from a child during the first hour, via a monkey ['apa', the Swedish word, means both 'monkey' and 'ape'] shooting an arrow during the seventh (and hottest) hour, to an old man (often with the head of a ram) during the last hour..."

I think we should take notice of 'the hottest hour'; the extreme point is what should be hit by this arrow. I suspect that necessary and important 'killing' in 'another picture language' is called 'breaking the coconut' or beheading in other ways - cfr at solstices in the Gateway of the Sun.
