Works of Sahl and Masha'allah

Collection of light means two principals connect to a common, slower recipient; Sahl interprets the collector as a possible judge, arbitrator or helper. The collector's required place or witnessing of the matter's place, and the Ascendant/matter rulers, remain unestablished. Lilly's reception branch is separate.

Prohibition means an intervening connection prevents the principals' intended perfection; its general meaning is interruption of the attempted union. The retained 6-degree detector has narrower coverage than Lilly's p.111 example. Its subtype and constant-speed ordering are normalized estimates; a matter's failure is not established.

Translation of light means an intermediary carries a departing planet's nature to another connection, giving the general meaning of mediation between the principals. Source-specific planetary orbs and the roles of parties are not established by the generic contact test.
