bathing illustrations and ritual purification

[Koen G]

I've been thinking about Diane's suggestion of them representing constellations, and though it's not my preferred idea, I must say there is something to it.

For example, it's important which parts of the constellation are hidden, which could be represented by the left hand specifically being tucked away. The 'eye' of a constellation is often an important star. And constellations can move into each other.

I'm no expert on star stuff, but I suspect this approach may have a lot of explanatory power.
