Free Lot of Marriage Calculator

The Lot of Marriage (also called the Lot of Union) is a calculated point in Hellenistic astrology that astrologers use to inspect committed partnership topics. It is derived from Venus (the planet of attraction, affection, and the desire for union) and Saturn (the planet of commitment, duration, and structural bonds), connecting the impulse to love with the symbolism of structure and duration.

Unlike most Hermetic lots, the Lot of Marriage has two traditional formulas. Dorotheus of Sidon (Carmen Astrologicum II.2 and II.3) is the primary source: he gives the first formula (Ascendant + Venus - Saturn) for men's marriage and the second (Ascendant + Saturn - Venus) for women's marriage, the same by day or night. Vettius Valens used different marriage-bringer formulas, so the Venus/Saturn pair here is Dorothean rather than Valensian. This calculator shows both results, allowing you to compare two traditional partnership testimonies in your chart.

Venus and Saturn may seem like an unlikely pair, but their combination captures the full arc of committed partnership. Venus supplies the attraction, the pleasure of companionship, and the desire to share life with another person. Saturn supplies the structure, the willingness to endure difficulty for the sake of the bond, and the capacity for loyalty that outlasts initial infatuation.

Read Venus and Saturn as symbolic poles, not as a verdict on any marriage. The Lot of Marriage shows where these two factors meet in your chart, suggesting one way to compare desire, commitment, and obligation in partnership questions.

The Lot of Marriage is closely related to the Lot of Eros, which represents desire, passion, and the raw attraction that draws people together. Where Eros describes what you want and who you are drawn to, Marriage describes what you commit to and how you sustain a bond over the long term. Together they map the full spectrum of intimate relationship, from initial spark to enduring union.

Studying both lots can show whether your desire and commitment testimonies align or pull in different directions. When Eros and Marriage share a sign or house, passion and commitment reinforce each other naturally. When they occupy different signs, the challenge is integrating what attracts you with what sustains you. Calculate all the lots with the Arabic Parts Calculator to see the full picture.
