Haiz (Arabic)

ha-YIZ

arabic: حيز (Haiz)

Definition

Haiz is a compound condition marking a planet fully at home with the day-or-night character of a chart. Sect divides a chart into a day side and a night side, set by whether the Sun is above or below the horizon. A planet already rejoicing in sect (a state called ḥalb) reaches haiz when several further conditions line up at once. In its full medieval form (Bonatti, Liber Astronomiae Vol XI, Part III) haiz needs a sect-match, a hemisphere-match, a gender-match, and angular placement. The Arabic ḥayyiz means "scope, domain, range"; Latin sources give it as hayz or haym.

In Tradition

Arabic-Persian astrologers treat ḥayyiz as a stacked, intensifying condition rather than a simple yes-or-no check. As Dykes notes in his Persian Nativities Vol I gloss, ḥayyiz first translated the Greek hairesis ("sect"), but came to mean the strengthened form of an underlying ḥalb — the basic match between a planet and the chart's day or night hemisphere. Bonatti, following Alchabitius, treats the same doctrine under the Latin term Dustoria, and requires all four sub-conditions to hold at once for the full state.

In Practice

You first read the chart's sect — whether the Sun sits above or below the horizon — then check each of the seven traditional planets against four things. One, sect-match: a day planet (Sun, Jupiter, Saturn) in a day chart, or a night planet (Moon, Venus, Mars) in a night chart. Two, hemisphere-match: by day a day planet is above the horizon and a night planet below, and the rule flips by night. Three, gender-match: a masculine planet (Sun, Mars, Jupiter, Saturn) in a masculine sign — fire or air — or a feminine planet (Moon, Venus) in a feminine sign — earth or water. Four, for the strict Bonatti-Alchabitius reading, angular placement in the 1st, 4th, 7th, or 10th house. A planet meeting all of these is in haiz, and reads as expressing what it signifies with its fullest sect-consonant strength. Some modern traditional astrologers (Brennan, Hand) ease the gender or angularity requirement and count sect plus hemisphere as enough.

Historical Origin

Ḥayyiz is attested in 9th-century Arabic natal handbooks, including 'Umar al-Tabari's Three Books on Nativities and Abu 'Ali al-Khayyāt's On the Judgments of Nativities (preserved in Dykes's Persian Nativities Vol I-II, drawn from Arabic public-domain originals). The compound Bonatti-Alchabitius form, Dustoria or Hayz, is set out in Bonatti's Liber Astronomiae Vol XI Part III (13th-century medieval Latin, public domain).
