**Morinus (Morin), Jean-Baptiste**[Astro*Index]

(l583-1656) known as Morinus, also known as Morin de Villefranche. French physician, mathematician, and astrologer.

The personal astrologer to Cardinal Richelieu, he correctly predicted the Cardinal's death, as well as the deaths of Louis XIII, Wallenstein, and Gustavus Adolphus. His major work is Astrologia Gallica, published in 1661. His major contribution was to reinterpret Ptolemy in light of the scientific advances of the seventeenth century. He invented the Morinus House System.

**Morinus House System**[Astro*Index]

Named after Jean-Baptiste Morin (1583-1656), known as Morinus. A *house system* which forms *house circle*s by *great circle*s which pass through the poles of the *ecliptic*, and through points which are spaced at 30°-intervals along the *celestial equator*, beginning with the intersection of the celestial equator and the upper *meridian*. The cusps are determined by the intersections of these house circles and the ecliptic. The *lune*s are not of equal size, the *midheaven* is the not the same as the 10th cusp, and the *ascendant* is not the same as the 1st cusp. The house circle for the 1st house passes through the *east point* of the horizon. The cusps of the Morinus system are determined independent of *geographical latitude*, and so a single *table of houses* suffices for all latitudes.

**Morinus House System**[Prima]

One of several house systems.

This system is named after Jean Baptiste Morin de Villefranche (1583-1656), who was an astrological consultant for Cardinal Richelieu.

It uses great circles that pass through the poles of the ecliptic and through points that are spaced at 30-degree intervals along the celestial equator, beginning with the intersection of the celestial equator and the east point. The cusps are determined by the intersections of these great circles and the ecliptic. The lunes of the houses are not of equal size. The MC does not denote the 10th cusp, nor the ascendant the 1st cusp. The 1st cusp lies on a great circle that passes through the east point of the horizon.
