This type of glyph indicates the colour red. As the planet Mars universally is regarded as having a red hue, this type of glyph ought to be found in Tuesday (the day in the week ruled by Mars).


1. Perhaps this type of glyph is used for showing the colour red just because it indicates the planet Mars, first as a sign for Mars and then as red in general.

2. If we scrutinize the two glyphs in Tuesday we find that they are not exactly alike: The first glyph has its 5 rightward markings fairly even spaced, whereas the second glyph has its corresponding 5 glyphs spaced as 1 + 4 (as seen from the bottom).

Perhaps this is a way to indicate that Mars shows to 'faces', one (the first) ordinary as a planet should, while the second 'face' is strangely variable: sometimes far away and faint (1), sometimes close up and luminous (4). This double-face is a consequence of the fact that Mars is our closest outer planet. Its orbit will move it so that it can be seen either 90 degrees to the left or 90 degrees to the right of the line towards the sun (as regarded from the Earth). Or it can be far away on the other side of the sun, or close by when Earth is between Mars and the sun.

Possibly the meaning of the first glyph is to show the ordinary view, whereas the second glyph is meant to show the seemingly slow movement of the faint Mars on the other side of the sun (1) and the quick movement of the strong Mars against the background of the stars when Mars is as its closest approach to the Earth (4).
