Haiz (Halb)

HAY-iz

arabic: حيز (Haiz)

Definition

Haiz is a medieval Arabic-Persian condition that fortifies a planet (Arabic ḥayyiz, carried into Latin as Hayz or Dustoria). A planet is in haiz when it agrees with the chart's sect — its day or night character — on several counts at once: it matches the chart's diurnal or nocturnal sect, it sits in the right hemisphere (above the horizon by day or below by night, with the reverse for nocturnal planets), and it occupies a sign of matching gender (masculine planet in masculine sign, feminine in feminine). Mars is a per-author exception, needing a masculine-by-day or feminine-by-night placement.

In Tradition

In medieval Arabic-Persian and traditional Western practice, haiz is read as the fullest sect-based strengthening a planet can have — every condition of its sect is satisfied at once, so its meanings are read at full force. Robert Hand's Night and Day: Planetary Sect in Astrology shows the doctrine surviving in medieval Arabic and Latin sources even after the reasoning behind it had partly faded; Bonatti draws together Alchabitius (al-Qabīṣī) on this compound condition.

In Practice

You first work out the chart's sect — diurnal if the Sun is above the horizon, nocturnal if below — then test each planet against three questions. First, does the planet's own sect match the chart's? Second, is it in its preferred hemisphere — above the horizon for day planets in a day chart, below for night planets in a night chart, and the reverse mappings otherwise? Third, is it in a sign of matching gender? When all three hold, the planet is in haiz and read as fully sect-fortified. The condition is counted alongside the usual tally of accidental dignity — strength from placement — and some authors, following the Alchabitius reception, add placement in an angular house and a square to a luminary as further sub-criteria.

Historical Origin

The doctrine descends from medieval Arabic-Persian astrology — al-Qabīṣī (10th c.), Sahl ibn Bishr, Masha'allah, and Abu Ma'shar — and was drawn together in the Latin transmission through the 12th-century translators John of Seville and Hugo of Santalla. Bonatti's Liber Astronomiae Vol XI Part III Ch VII ("Dustoria / Hayz") preserves the al-Qabīṣī compound formulation. Hand's Night and Day: Planetary Sect (1995) reconstructs the doctrine for the modern traditional revival.
