Decan Specifications
ḫt ḫꜣw Decan 21 represents the final segment of Libra, spanning 200° to 210° of tropical solar longitude. Under the Chaldean governance of Jupiter, this decan expands the seeker’s horizon toward broad social ideals, philosophical justice, and benevolent diplomacy.
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 ḫt ḫꜣw (“Rear of the Thousands”).

Chaldean Ruler: Jupiter
