Porphyrius Pallas Birth Chart Calculator

This calculator uses Porphyrius house system and Pallas Athena (asteroid).

The Porphyrius house system, named after the 3rd-century philosopher Porphyry, is a quadrant system that divides the space between the angles (Ascendant, IC, Descendant, MC) into three equal parts. It is one of the oldest house systems still in use today.

Pallas (Pallas Athena) is one of the four major asteroids and represents wisdom, creative intelligence, and strategic thinking. In astrology, Pallas shows our problem-solving abilities, pattern recognition, and capacity for diplomacy. This calculator displays Pallas alongside the traditional planets.
