Chaldean Order Cycle: Step 7 of 7 in the classical descending planetary sphere sequence.
Decan 35 spans 340° to 350° of tropical solar longitude, forming the central decan of Pisces. Ruled by Jupiter in the Chaldean system, this decan represents the pure, boundless expression of compassionate wisdom, intuition, and spiritual optimism.
Historical Context
In ancient Egypt, decans originated as a system of 36 asterisms (baktiu) observed rising heliacally before dawn across 10-day intervals (decades) to measure the nocturnal hours and agricultural seasons. In the documented Hellenistic-Egyptian tradition (Dendera circular planisphere, Hephaestio of Thebes 1.1, and Liber Hermetis 25), this sector is identified as spdt (“Sopdet (Sirius / Sothis / Isis)”).
