2. As to the names of δ and θ Leonis Allen has the following information:

"Zosma and Zozma are from ζωσμα, an occasional form of ζωμα, the Girdle, found in the Persian Tables; but its propriety as a stellar title is doubtful, for the star is on the Lion's rump, near the tail. Ulug Beg very correctly termed it Al Thar al Asad, the Lion's Back, which has become Duhr and Dhur of modern catalogues.

With θ, on the hind quarter, it constituted the 9th manzil, Al Zubrah, the Mane, and itself bears this name as Zubra, - strange titles for star and station so far away from that feature of the animal.

δ and θ also were Al Kāhil al Asad, the Space between the Shoulders of the Lion; and Al Harātān, sometimes transcribed as Chortan, and translated the Two Little Ribs, or the two Khurt, or Holes, penetrating into the interior of the Lion; but all these seem as inapplicable as are the other titles.

In India they marked the corresponding nakshatra, Pūrva Phalgunī, δ being the junction star between the two Phalgunī asterisms ..."

"θ in the manzil Al Zubrah, shares with δ the title Al Harātān, Al Bīrūnī saying that 'when they rise Suhail is seen in Al Izak', - wherever this may be. The Century Cyclopedia gives Chort as the individual name, from the combined title ..."

We should now consider the system of Arabic manzils in order to compare it with the system of Hindu nakshatras and with the G text. Wikipedia:

"In the traditional Arabic astrological system, the moon was seen to move through 28 distinct manazil (singular: manzil) during the normal solar year, each manzil lasting, therefore, for about 13 days.

One or more manazil were then grouped into a nawaa (plural anwaa) which were tied to a given weather pattern. In other words, the yearly pattern was divided in the following manner: A year was divided into anwaa, each of which was made up of one more manazil, which were associated with a dominant star or constellation. These stars and constellations were sometimes, but not always, connected in some way to constellations in the Zodiac. Moreover, as the anwaa repeat on a regular, solar cycle, they can be correlated to fixed points on the Gregorian calendar ..."

Redmarked manazil have other numbers of days than 13 (which I regard as a Sign).
