Bonification and Maltreatment

Definition

Bonification and maltreatment are a matched pair of Hellenistic ideas about how one planet's state is changed by what other planets do to it. Bonification (Greek euergesia) is the help a planet gets from the helpful planets — mostly Venus and Jupiter — through a sign-based aspect, sharing its sign, or ruling it. Maltreatment (Greek kakōsis) is the harm a planet takes from the difficult planets — mostly Mars and Saturn — through those same channels. Both work through the type of aspect involved (sextile, square, trine, opposition) and both depend on sect, your day-or-night birth status.

In Tradition

In Hellenistic astrology, bonification and maltreatment are read together as one doctrine, both shaping a planet's ability to deliver what it stands for. A planet that is otherwise well placed by sign and dignity can have its work cut down by maltreatment from an out-of-sect difficult planet; a planet that is otherwise weakly placed can have some of its work restored by bonification from an in-sect helpful planet. Neither replaces a planet's essential dignity or sect — they layer on top of those.

In Practice

Once you know a planet's sign, dignity, and sect standing, you look at the aspects it receives. You read bonification when a helpful planet aspects it — especially the in-sect helpful one (Jupiter by day, Venus by night) — and the kind of aspect scales the support: trine and sextile are gentler and more reliably delivered, square and opposition more conditional. You read maltreatment when a difficult planet aspects it — especially the out-of-sect difficult one (Mars by day, Saturn by night) — with squares and oppositions hitting hardest and trines and sextiles landing softer. The most intense forms are co-presence (a planet sharing the sign) and besiegement, where a planet is hemmed in between two difficult planets with no helping aspect to relieve it. This pair sits alongside reception, sect, and the busy-versus-cadent house distinction (the Greek chrematistikos houses versus the cadent ones) as one of the main classical things astrologers weigh to judge whether a planet can actually deliver what its sign placement promises.

Historical Origin

The bonification-and-maltreatment doctrine runs through the foundational Hellenistic sources — Dorotheus of Sidon (Carmen Astrologicum, 1st century CE), Vettius Valens (Anthologiae, c. 145–175 CE), and Ptolemy (Tetrabiblos, c. 150 CE). Its vocabulary was preserved through the Arabic transmission and returns in modern English through the Project Hindsight translations and Brennan's Hellenistic Astrology synthesis (2017).
