The sixth house entry is one of several places where astrological technique preserves the social order of the societies that built it, and the atlas records that rather than tidying it away.
The Hellenistic and medieval texts on this house concern household dependants, in worlds where a substantial part of that dependency was unfree. Dorotheus of Sidon treats the buying of slaves among the inceptions in the fifth book of the Carmen Astrologicum, and the later Arabic and Latin compilations carry the material forward. The technique treats a person as the subject of an election in the way it treats a journey or a purchase, and no amount of retranslation into the language of employment makes that disappear.
Two things follow. The first is descriptive honesty. An atlas of correspondences that quietly replaces every mention of a slave with the word employee misrepresents its sources, and a reader who then meets the originals finds them very different from the summary. The second is that the sixth house's modern meaning, work, service, routine and health, is a real change in doctrine and not merely a change in wording. The relation the house now describes is one a person can leave.
The atlas therefore names both: what the tradition recorded, in the terms it recorded it, and what practitioners take the house to mean today. Living traditions are described here rather than prescribed, and the historical material is presented as history.
