The sun or moon can be shown in a similar type of display - like a stick insect with many legs. For example in L6 one sees bottom left a portrayal of the sun at noon as it is higher in summer and lower in winter, this accompanying the lower register of L6 as being about, to the right, day-inch counting based upon sunrises in the east, or the year displayed with the solar paths over that period. In L6 this pattern uses a ridge in the stone itself to represent the locations of the sun to the south over the year.
Gavrinis Stone L6, lower register.
To the left is a vertical channel between concentric paths,
coinsident with an edge in the stone.
In stone C4 this type of figure is used differently, so as to show the movement of the southernmost extremes of the moon which occur when the moon is in the region of the winter solstice on its orbit which, according to the location of the descending node of the moon, will move between maximum standstill (lower than the sun's path) and minimum standstill (higher than the sun's path, at winter solstice).
The same vertical path is shown but this time as a range of locations of the moon between maximum and minimum standstills. At the top of the range is the moon shown as a disc cupped by its orbital path in a way symbolic of "minimum". The point at which the moon enters the minimum Half cycle (lasting 9.3 years when the moon rises and sets on the horizon within the solsticial extremes of the sun) is shown using a double square drawn as a 1 by 2 right triangle linked to the vertical line via three bands so that the lowest groove crosses the vertical in a clear cross.
The line below this crossing therefore belongs to the moon's location, further south than the sun at winter solstice and therefore in the maximum standstill half cycle of the lunar nodal period. The unique symbols to left and right must therefore reference the maximum standstill.
