Al Thurayya

Al Thurayya, the first mansion in Robson's traditional ordering, takes its name from the Pleiades star cluster, one of the most celebrated asterisms in all of human history. This mansion carries themes of abundance, collective endeavor, and the gathering of resources. Its influence is described as profitable for sailors, huntsmen, and alchemists, suggesting a connection to activities that require both skill and favorable timing.

When planets or the Moon transit Al Thurayya, the atmosphere favors practical undertakings, particularly those involving collaboration or the harvest of natural abundance. The Pleiades have been associated across cultures with agricultural cycles, rainfall, and the marking of seasonal transitions, and this mansion inherits that deep connection to earthly rhythms.

Al Thurayya holds the first position in the traditional Arabic ordering, which begins at the Pleiades rather than at 0 degrees Aries. This reflects the ancient practice of starting the lunar calendar when the Pleiades rose with the Sun, a convention shared across Babylonian, Arabic, and early Greek astronomy. The mansion's placement at the head of the series gives it a quality of initiation and new beginnings within the manzil framework.

When the Moon passes through Al Thurayya, it is a favorable time for planting, sowing, and beginning practical ventures. Traditional electional guidance counsels against marriage or sea travel during this transit, suggesting that the mansion's energy is best directed toward material productivity rather than emotional or relational matters. The collective, gathering quality of the Pleiades makes this a good period for group activities and cooperative work.

With Moon here in the case of an election, plant and sow but do not marry or travel by water.

This catalog anchors each manzil to its determinant star in Robson's star-based ordering, with positions given in the J2000 frame. Mansion boundaries here follow the stars, so their widths are uneven and they drift with precession.

The daily Moon mansion on your Today page uses the tropical equal reckoning instead: 28 divisions of 12 degrees 51 minutes 26 seconds measured from 0 Aries, the convention of the Indian elections reported by al-Rijal in The Book of the Skilled VII.101, printed pages 61 through 73 in Benjamin Dykes, Choices and Inceptions: Traditional Electional Astrology (Cazimi Press, 2012). The two conventions name different mansions for the same Moon on many days, which is why each surface states which one it is using.

Where that electional branch grades undertakings as favorable, middling, or cautioned, those grades are historical classifications recorded in the source. They report what the tradition wrote about a mansion, and they judge nothing about your day.
