From basic Fortuna to complete Paulus Alexandrinus system
Everything you need to know about authentic Hermetic Lots
Access 97+ Arabic Parts (also called Lots), including the complete set of Hermetic Lots from Paulus Alexandrinus (4th century CE). The term 'Arabic Parts' is traditional in Western astrology, while 'Hermetic Lots' refers to the original Hellenistic system. Our API implements the authentic hierarchy where Eros and Victoria depend on Spirit, while Nemesis depends on Fortuna. House-based lots like Marriage, Death, and Career use precise cusp calculations. This is the most complete implementation available, combining Arabic and Hellenistic traditions.
Our API provides the complete set of Hermetic Lots from classical Hellenistic astrology: Fortuna (material success), Spirit (soul purpose), Eros (passionate desire, calculated from Spirit), Victoria (success and conquest, also from Spirit), Nemesis (retribution, calculated from Fortuna), plus Necessity, Courage, and 90+ additional lots.
This hierarchical system, where some lots depend on others, creates a sophisticated network of life themes that ancient astrologers used for timing and prediction.
Unlike simple calculators that use simplified formulas, our API automatically applies correct day and night formulas based on Sun position.
Fortuna uses ASC + Moon - Sun for day births, but reverses to ASC + Sun - Moon for night births, ensuring traditional accuracy.
Our API correctly implements the dependent calculations that make Hermetic Lots unique: Eros (passionate desire) and Victoria (triumph) are calculated from Spirit, not from the Ascendant.
Similarly, Nemesis (divine retribution) depends on Fortuna.
This hierarchical system, documented by Paulus Alexandrinus, creates interconnected life themes where spiritual development (Spirit) influences passion (Eros) and success (Victoria), while material fortune affects karmic balance (Nemesis).
Beyond planetary lots, we calculate sophisticated house-based lots that require precise cusp positions: Lot of Marriage (using 7th house cusp), Lot of Death (8th house), Lot of Career (10th house), and dozens more.
These calculations follow the original formulas from Paulus Alexandrinus and Vettius Valens, providing insights into specific life areas that simple planetary aspects don't show.
Professional astrologers use these for timing life events with remarkable accuracy.
