*Ca14-23 is special in showing 'feathers' only on the 'outside'. The glyph can possibly be regarded as a combination of maro and nuku:

maro	*Ca14-23	nuku

The effect is as if a solid body had intruded in the center, intercepting most of the 'light rays' - as if it was a solar eclipse.

*Ca14-23 is located at winter solstice and at that time sun light is weak. At a certain time all the fires are extinguished in sympathy with the sun.
