Collection of Light in Horary Astrology
Collection of light is when both significators apply to a common third planet, which collects their combined light even though the two never aspect each other directly. It's translation of light's mirror image: instead of one planet carrying light between the two, a third planet gathers it from both.
Horary astrology is a traditional, rule-based symbolic practice with no empirical scientific basis -- treat this page, and Querens itself, as entertainment and a genuinely interesting historical system, not fact.
What Lilly says
Christian Astrology, p.110-113 (1647 ed.)
Collection sits alongside translation of light in Lilly's discussion of ways a matter can still perfect without the significators themselves ever forming an aspect -- here, by both of them reaching toward the same third planet.
How Querens reads this
Querens checks every other traditional planet for one that both significators are currently applying to. If it finds one, the matter is treated as perfected through that collector, the same as a direct aspect would be, and it's named explicitly in the rule trace rather than folded silently into a generic result.

Frequently asked questions
- What is collection of light?
- When both significators apply to the same third planet, which is read as collecting their combined light even without a direct aspect between them.
- How is collection different from translation of light?
- Translation carries light between the two significators via a third, faster planet. Collection is both significators applying to the same third planet at once.
- Does Querens's engine check for collection of light automatically?
- Yes -- it's checked on every reading, alongside translation of light and a direct aspect, as one of the ways a matter can perfect.
