The Part of Fortune, also known as the “Lot of Fortune” or simply “Fortuna,” is a significant point in astrology that represents where an individual can find success, happiness, and material well-being. It is not a physical body like a planet or asteroid but rather a calculated point derived from the positions of the Sun, Moon, and Ascendant. The Part of Fortune is traditionally associated with luck, prosperity, and the areas of life where one is likely to find fulfillment.

1. Calculation of the Part of Fortune:

• The Part of Fortune is calculated differently depending on whether the person was born during the day or at night:
  • Daytime Births (Diurnal): For a person born during the day (when the Sun is above the horizon), the Part of Fortune is calculated by adding the Ascendant to the Moon’s position and then subtracting the Sun’s position. The formula is: $$\text{Part of Fortune}=\text{Ascendant}+\text{Moon}-\text{Sun}$$
  • Nighttime Births (Nocturnal): For a person born at night (when the Sun is below the horizon), the formula is reversed: $$\text{Part of Fortune}=\text{Ascendant}+\text{Sun}-\text{Moon}$$
• The resulting degree of the zodiac is where the Part of Fortune is located, and this point is interpreted in the natal chart.

2. Significance of the Part of Fortune:

• Success and Material Well-being: The Part of Fortune is often linked to material success, financial prosperity, and the general well-being of the individual. It shows where and how a person might find abundance and achieve their goals. The sign and house position of the Part of Fortune can indicate the types of activities or areas of life that are most likely to bring success and happiness.
  • Example: A Part of Fortune in Taurus might indicate that success comes through financial stability, appreciation of beauty, or engagement with the physical world. In contrast, a Part of Fortune in Aquarius might suggest that success is found through innovation, social causes, or working with technology.
• Happiness and Fulfillment: Beyond material success, the Part of Fortune is also associated with overall happiness and the sense of fulfillment. It reflects the activities, environments, and relationships that bring a person joy and satisfaction. It can be seen as a guide to what will make the individual feel truly fortunate in life.
  • Example: A Part of Fortune in the 5th house (associated with creativity, pleasure, and children) might indicate that happiness comes through creative expression, artistic pursuits, or nurturing others. In the 11th house (associated with friendships, social networks, and hopes for the future), it could point to finding joy through community involvement and shared ideals.

3. Interpreting the Part of Fortune:

• Sign Placement: The zodiac sign in which the Part of Fortune is placed provides insight into the nature of the success and happiness one might achieve. It suggests the qualities or approach that will be most beneficial.
  • Example: A Part of Fortune in Leo might suggest that embracing leadership, creativity, and self-expression will lead to success. In Virgo, it might indicate that attention to detail, service to others, and practical skills are key to achieving prosperity.
• House Placement: The house in which the Part of Fortune is located reveals the area of life where one is likely to find the most fortune and fulfillment. Each house governs different aspects of life, such as career, relationships, health, or spirituality.
  • Example: If the Part of Fortune is in the 10th house, it suggests that career and public life are areas where the person can achieve significant success and recognition. In the 4th house, success might be found through home, family, or real estate.
• Aspects to the Part of Fortune: The aspects (angles) that other planets make to the Part of Fortune can enhance or challenge its influence. Favorable aspects (such as trines or sextiles) from benefic planets like Venus or Jupiter can increase the likelihood of success and ease. Challenging aspects (such as squares or oppositions) might indicate obstacles that need to be overcome to achieve happiness and prosperity.
  • Example: A conjunction between the Part of Fortune and Jupiter could indicate great potential for wealth and success, while a square from Saturn might suggest that hard work, discipline, or delays are necessary before success is achieved.

4. The Part of Fortune in Transits and Progressions:

• Transits: When transiting planets (especially the Sun, Moon, Venus, or Jupiter) aspect the Part of Fortune, it can signal times of increased opportunity, success, or happiness. These transits can activate the potential of the Part of Fortune, bringing material rewards or emotional fulfillment.
  • Example: A transit of Jupiter over the Part of Fortune might bring a period of growth, expansion, and good fortune in the areas indicated by its placement.
• Progressions: Progressed planets aspecting the Part of Fortune can also mark significant periods of personal development related to success and happiness. These progressions can indicate shifts in how one experiences and achieves fortune in life.
  • Example: A progressed Moon conjunct the Part of Fortune could signify a time when emotional needs and material success are aligned, leading to a period of personal contentment.

5. Cultural and Historical Perspectives:

• Traditional Astrology: In traditional astrology, the Part of Fortune was often used as a key indicator of wealth and prosperity, particularly in horary astrology (the branch of astrology that answers specific questions). It was considered one of the most important points for determining outcomes related to material success.
• Modern Astrology: In modern astrology, the Part of Fortune is still viewed as significant but is often interpreted in a broader context, encompassing not just material wealth but overall well-being and life satisfaction.
