Not that I've seen, but others have read e.g. Valens much more carefully than I. Perhaps Chris Brennan could answer this, if he's following the thread.
What I am interested in is the historical use of primaries in the renaissance period and afterwards. I assume they are mostly giving priority to Ptolemy over other traditions by then? The question is when do references to the bound lord get dropped altogether?
Yes, Ptolemy is
the authority in the Renaissance. As for the terms, Morin rejects them, but they're still there (albeit not very emphasized) in William Lilly, so it was probably a gradual process. Worsdale in the 19th century rejected the traditional terms but calculated his own terms in a different way which (as far as I've been able to make out) he never explains -- but it's probably based on Placidean ideas. (Placidus himself used the traditional terms.) So the point where they were lost altogether is probably quite recent, within the last 200 years.
And when does the focus shift to calculating every possible direction rather than ones restricted to the ASC or hyleg?
To some extent, that strand is present all along. Valens (IV.29) has the following quotation ascribed to Hermes (transl. Riley):
Valens wrote:It is necessary to make the progression [peripatos, the word that some translate as 'circumambulation' - MG] from all the stars to all the other stars according to the rising times of the signs in each klima. For example: for a wife, daughters, or female individuals, calculate from Venus; when forecasting concerning actions or related matters, calculate from Mercury; when forecasting about dangers, death, sickness, or bleeding, calculate from the malefics in aspect with the Ascendant, the sun, or the moon. Similarly for the other matters. It is also necessary to note the terms in which the progressions are located, which stars are casting rays, and which stars are transiting the sign of the progression. Likewise note how the transmitter and the receiver relate to the nativity, how they rose, and how they were at the nativity.
Similar passages are found in several of the medieval Arabic authors. Morin strongly advocated this (saying that the terms were invented to explain events that could be more properly explained using the non-luminary planets as significators), and Lilly mentions it as well. But most authors kept to the Ptolemaic five, or added only the prenatal syzygy, and this is true even in the late 19th century. The wholly modern way of directing anything to anything (as in the so-called Topocentric system) is very recent, post WWII, I think.
