No text, but a visual code

 a notation in which the sun and moon serve to help locate the zodiacal stars in the ecliptic.

That is worth thinking about Antonio, thanks. A proposal for how the notation works in practice. 

It seems to be something like that. It is an awkward way to locate zodiacal stars, or to pinpoint degrees of the ecliptic, but it seems to work like that. You take one cycle (solar) and the other (lunar) and run them against each other, or on top of each other, and they meet at particular degrees of the zodiac, each of which is identified with a star. So you arrive at the star sort of by a process of elimination, indirectly. You divide the ecliptic up in various ways until only one degree shares all the divisions. (It reminds me of a way of locating prime numbers.)
