In classical astrology, Terms (Bounds) and Faces (Decans) are secondary dignities that provide additional nuance to planetary strength. These ancient systems help astrologers determine how comfortably a planet expresses its energy.

1. Terms (Bounds / Egyptian Bounds)

• Definition: Terms divide each zodiac sign into unequal segments ruled by different planets.
• Purpose: Provides secondary dignity, influencing a planet’s effectiveness and subtle influence in a chart.
• Key Use: Especially important in Hellenistic astrology and Horary charts.

Example:

• Aries (0°–30°) → Mars rules 0°–6°, Venus 6°–14°, Mercury 14°–20°, Jupiter 20°–26°, Saturn 26°–30°.
• A planet in Mars’s term → expresses assertiveness and courage more strongly.

2. Faces / Decans

• Definition: Each zodiac sign (30°) is divided into three equal 10° parts called faces or decans.
• Purpose: Sub-ruler of each decan adds nuance to the planet’s expression.
• Example:
  • Aries Decans:
    • 0°–10° → Mars (core Aries traits)
    • 10°–20° → Sun (adds creativity, leadership)
    • 20°–30° → Jupiter (adds optimism, expansiveness)

3. How to Use Terms and Faces in Chart Interpretation

1. Identify the planet’s degree in its zodiac sign.
2. Check which term (bounds) it occupies → indicates secondary dignity.
3. Check which face (decan) it occupies → adds nuance to personality and energy expression.
4. Combine with primary rulership, modality, element, house placement, and aspects for detailed interpretation.

✅ Summary

Terms (Bounds) and Faces (Decans) are classical tools that provide subtle layers of planetary dignity and influence. They help astrologers interpret how comfortably a planet expresses its energy and how it affects chart outcomes.
