What is absent?
The two LUMINARIES, the Sun and Moon are nowhere to be seen in TDB artwork, except metaphorically.
The three dots could represent the SUN, the EARTH and the MOON and their ways of eclipsing each others.
NOTE: One of the most prominent
ABSENCE from TDB is to be guessed from the PAGE NUMBERS. The numbering
of the pages uses the most important LANGUAGES of the world. BUT ARABIC is ABSENT!!!!!
The cultural and / or spiritual CAPITAL of the arabic world is CAIRO, in Egypt. This could weel be a major clue to solve the Enigma...
The use of ellipsis is also a mark of absence.
1570, from L. ellipsis, from Gk. elleipsis "a falling short, defect, ellipse," from elleipein "to fall short, leave out," from en- "in" + leipein "to leave" (see relinquish). Grammatical sense first recorded 1612.
c.1280, from O.Fr. eclipse, from L. eclipsis, from Gk. ekleipsis "a leaving out, forsaking, an eclipse," from ekleipein "to forsake a usual place, fail to appear, be eclipsed," from ek "out" + leipein "to leave" (cognate with L. linquere; see relinquish). The celestial ecliptic (c.1391) is the circle in the sky followed by the Sun, so called because eclipses happen only when the Moon is near the line.
