That's not the point, JA.
Nobody's disputing the Ptolemaic tables, which you posted twice. Sect is irrelevant. Your thread title is about how ancient texts support Mercury as the ruler of astrology. [Which obviously is the only type of astrology an ancient text could support. Duh, uh.] Ptolemy's table (or the Egyptian terms, for that matter,) do not address this question. Mercury's planetary strengths and weaknesses in the horoscope say nothing about its rulership of astrology. Ptolemy giving Mercury authority over astrologers does say something about it.
You might want to look at the hermetic writings ["hermetic"= of Hermes, the Greek name for Mercury] attributed to Hermes Trismegistus, an amalgam of the Greek god Hermes and the Egyptian scribe god Thoth. Writings attributed to Hermes Trismegistus were probably penned by several authors in Egypt during the early decades CE. But these authors point to the Egyptianized Greek god Hermes as the founder of astrology, at least its more magical ancient uses.

Please identify some ancient texts for us giving Mercury the rulership of astrology, like Manilius,
Astronomica.
Since you're a big fan of Vettius Valens, you might have pointed out what he says about Mercury in Book One of his
Anthologies: "It also rules those skilled interpreters of the
heavens."
