Hyleg

The significator of longevity in a horoscope. If the sun occupied an aphetic place, it became Hyleg. Otherwise, the moon was next tested. If neither, the planet which had the most Dignities at the preceding lunation. Otherwise, the ascendant for a day birth; or, Fortuna for a night birth. The time required for the hyleg to progress to an aspect to the anareta was used as an indicator of the length of an individual's life. This practice is considered unethical by professional astrologers.
