Trine

Definition
An aspect of approximately 120 degrees (a third of the zodiac circle) between two planets. Traditionally read as harmony and easy flow, and classically linked to signs sharing the same element.
In more depth
The trine connects positions a third of the circle apart, which in the sign-based reckoning joins the three signs of one element: the triplicity triangles. The tradition, from the Hellenistic configurations through Lilly, counts it the most favourable of the regards.[1][2][3]
'Harmonious' is doctrine, not measurement; some modern practitioners also note interpretively that trine-heavy charts can indicate ease without impetus. Both readings are labelled interpretation on this platform.[3]
