8th – 11th century · Baghdad, Balkh, Khwārazm
Perso-Arabic
Inherited the Greek and Persian material and systematised it — degrees of dignity scored, aspects weighed by applying and separating, every judgement built up from parts that can be named. The most procedural of the five.
Who wrote it down
The authors are long out of copyright. Almost every English text of them is not — a modern translation is a living work of scholarship owned by its translator. So Jade paraphrases and names the chapter, and quotes directly only where an English text is itself in the public domain. Two of the nineteen sources are.
Abū Maʿshar al-Balkhī
787 – 886
Kitāb al-Madkhal al-Kabīr · Arabic
Turned inherited doctrine into a reasoned system, and through its Latin translation set the terms for four centuries of European astrology.

Māshāʾallāh ibn Atharī
c. 740 – 815
On Reception, and the astrological works · Arabic
The clearest early writer on reception — what it means when two planets are in each other’s places rather than merely looking at each other.
paraphrase only
Abū Rayḥān al-Bīrūnī
973 – 1048
Kitāb al-Tafhīm · Arabic
A sceptic writing a textbook: states each doctrine precisely and then says which authorities disagree, which is why it is the best single index of the tradition.

What each planet meant
Three answers for each: what this tradition took the planet to be, what it takes the planet to do, and what it makes of somebody born with it strongly placed. The third is the one that differs most between traditions, and the one a reading is built from.
Sun
- is
- The king of the planets, whose nearness burns and whose place confers rank on whatever stands there.
- does
- Dignifies, and consumes. A planet close to it is combust — present in the chart and unable to act.
- in a nativity
- Abū Maʿshar reads the Sun for standing granted rather than standing claimed, and weighs it against the lord of the rising sign: strong Sun with a weak ruler is somebody with authority they cannot actually spend.
Moon
- is
- The quickest significator, and the one the tradition watches most closely because it is the one that arrives first.
- does
- Applies and separates. Its next contact is read as what happens next, and the one it just left as what has just been settled.
- in a nativity
- Read for the body’s temper and for what it applies to next — the tradition’s clearest single idea. What the Moon is moving toward describes what somebody is about to do, which is not the same as what they are.
Saturn
- is
- The greater infortune, cold and dry, significator of age, of depth, of land, and of everything slow.
- does
- Withholds and delays — and confers, on whatever survives the delay.
- in a nativity
- Cold, dry and slow, and the Arabic writers give it the long view: what Saturn signifies arrives at the end of a process. A strong Saturn is not an easy life, it is a life whose late part is the substantial one.
Jupiter
- is
- The greater fortune, and the significator of law, of teaching, and of the kind of wealth that arrives through other people’s good opinion.
- does
- Prospers whatever it receives, in proportion to how well it is placed to do so.
- in a nativity
- The most generous significator and the one the tradition warns about hardest, because enlargement without judgement is just excess. Strong Jupiter means somebody is trusted; whether that trust is warranted is read elsewhere.
Mars
- is
- The lesser infortune, hot and dry, strong in its own places and dangerous chiefly when it has no dignity at all.
- does
- Cuts, and takes by force what is not given.
- in a nativity
- Hot and dry, and the Arabic material cares less whether that is bad than whether the chart can absorb it. Mars with somewhere to work is craft; Mars with nowhere to work is the same force turned inward.
Venus
- is
- The lesser fortune, governing ornament, music, agreement and the pleasant forms of exchange.
- does
- Reconciles. It makes parties willing.
- in a nativity
- Read for concord — what somebody can hold together, including people who would not otherwise be in the same room. Strained, the same faculty becomes an inability to let a disagreement stay a disagreement.
Mercury
- is
- The scribe, taking the nature of its companions and of the sign it stands in more completely than any other planet.
- does
- Transmits, and alters slightly in transmitting.
- in a nativity
- Takes the complexion of whatever it stands beside, so the tradition weighs it last, after everything else is settled. The intelligence is real; its direction is borrowed from the strongest testimony near it.
Rahu
- is
- The Head of the Dragon — where the Moon crosses north over the ecliptic, and where eclipses happen.
- does
- Increases whatever it joins, without discrimination and without a limit of its own.
- in a nativity
- The ascending node, taken as an amplifier that adds no judgement of its own. The counsel is to establish what it is amplifying before asking whether the amplification is welcome.
Ketu
- is
- The Tail of the Dragon, the southern crossing — the other end of the same axis.
- does
- Diminishes and detaches.
- in a nativity
- The descending node, read as separation and as expertise arrived at by subtraction — somebody is unusually good at a thing they have stopped wanting credit for.
