James Holden, Ancient House Division

James Holden, Ancient House Division is an astrological source represented here through cited material on houses, ascendant, midheaven, trisection, and alcabitius.

The cited material covers houses, ascendant, midheaven, trisection, and alcabitius.

In Holden's reconstruction of equal-house practice, the Ascendant degree anchors equal thirty-degree sectors while the astronomical Midheaven remains an independently sensitive point; it is not automatically substituted for the tenth equal-house cusp.

For the Rhetorius or Alcabitius-style equatorial method, Holden measures the right-ascensional arc from Midheaven to Ascendant, divides it into thirds, adds the thirds to the Midheaven's right ascension, and converts the resulting equatorial points back to ecliptic longitude.

Holden treats the ancient five-degree and twenty-five-degree offsets as an interpretive sector around a house division rather than evidence for moving every mathematical cusp; he preserves uncertainty about whether the convention marked an aphetic or operative zone.

This overview is limited to the cited portions. It does not stand in for the complete work, reproduce source passages, or make every documented technique a universal chart interpretation.
