In Part 1, which will be delivered on Sunday, October 26, at 5 pm GMT, I will talk about the roles of the Moon in observational astrologies, lunar “zodiacs,” Babylonian functions modeling the Moon’s motion, and non-horoscopic uses of the Moon in Hellenistic general and catarchic astrology.

Arguably, the Moon is the most important planet in most types of astrology. In the next HOROI Talk, “The Tales of the Moon,” I will cover the uses and historical development of lunar concepts and conditions. Due to the abundance of relevant material, this talk is split into two parts.

I mean, the querent produces or forms

My take is that H5 represents "children" in the broadest sense, including non-animate roles like artwork. Everyone/everything the produces or forms.

1. H5, if the teacher is the querent (H1), and the teacher-students dynamics are being investigated.
2. No. Under normal circumstances, I wouldn't use natural significators for main roles in the question.

I wonder if there's a lucky corner on the planet where most of them aren't clowns and/or baboons.

I agree. Rhetorius conflated a number of sources, including the model of the poets of the Manethoniana and, I believe, Teucer on the barbarous sphere.
