About this app

ARS ASTRORUM — THE CELESTIAL GRIMOIRE

Explore historical electional astrology and celestial magic through a modern astronomical engine.

Ars Astrorum begins with one question: WHAT DO YOU SEEK? Choose an intention — Great Fortune, Wealth & Commerce, Love & Attraction, Recognition & Influence, Knowledge & Revelation, Protection or Reconciliation — and the app searches the sky above your current location for the moments that best conform to the rules of the selected historical tradition.

A RENAISSANCE INSTRUMENT, REBUILT IN SOFTWARE
• Offline astronomy engine: positions of the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn, the Ascendant, Moon phase and major aspects
• Traditional planetary days and unequal planetary hours from your local sunrise and sunset
• The 28 lunar mansions, calculated mathematically
• Election search for tonight, 7, 30 or 90 days, or a custom period
• The top three elections, each scored for TRADITIONAL ELECTION CONFORMITY from 0 to 100

WHY THIS MOMENT?
Every score is explained. Tap any line to see the detected celestial condition, its effect on the score, and where the rule comes from: the source family (Dorotheus of Sidon, the Picatrix, Agrippa's Three Books of Occult Philosophy, the Ars Paulina), its provenance (historical, interpreted, reconstructed, synthesis or modern) and a confidence level. Where verified source data has not yet been entered, the app says so plainly instead of inventing it.

RITUAL COMPILER
Begin an operation in a focused ceremonial interface, with stages assembled from provenance-tagged components: preparation, celestial orientation, the planetary magic square (kamea), statement of intent, contemplation, closing — and a modern final step that asks what concrete action you will take in the real world. Modern practices are always labeled as modern.

PRIVATE BY DESIGN
No account. No ads. No analytics. No tracking. No internet access. Your approximate location is used only on your device to calculate sunrise, sunset, planetary hours and the Ascendant.

PLEASE NOTE
Ars Astrorum reconstructs historical traditions for educational, contemplative and entertainment purposes. Scores measure conformity to traditional astrological rules — not the probability that any outcome will occur. Astrology and ritual magic have not been scientifically shown to cause external outcomes such as wealth, love or fortune.
