malefic An archaic term applied to planets and aspects whose influence was thought to be negative or destructive. Traditionally, Saturn is the Greater Malefic; Mars, the Lesser Malefic. Uranus, Neptune and Pluto were also classed as malefics. The Square, opposition and other disharmonious aspects were once considered malefic aspects.
Mansions of the Moon, Moon Mansions Synonymous with Lunar Mansions. See Lunar Mansions.

mean motion Average motion or rate of travel within a specified time period.
medical astrology The branch of astrology devoted to the study of the human body, disease and health according to astrological symbolism portrayed in a horoscope.
Medium Coeli From the Latin, literally middle of the heavens; the culminating degree of the ecliptic, commonly called Midheaven, abbreviated MC. In an unequal house system the MC, one of the angles of a horoscope, forms the cusp of the tenth house.
meridian A great circle, encircling Earth, that passes through the North and South Poles. A line of longitude.
Metonic Cycle The nineteen-year cycle named for the Athenian astronomer Meton who discovered (ca. 432) that the new Moon occurs on the same day of the year at approximate nineteen-year intervals.

Midheaven The most commonly used term for Medium Coeli, usually designated by the initials M.C. See also Medium Coeli.
midnight ephemeris An ephemeris that lists astrological data exact at the beginning of the day, 12:00 A.M. Also called zero hour ephemeris (12:00 A.M. = 00:00:00). See also ephemeris.
midpoint A zodiacal point in a horoscope that is equidistant from two planets. Two midpoints exist for each pair of planets. Aspects to a midpoint activate the two planets involved. Interchangeable with half-sum. Midpoints are largely used by cosmobiologists. See also cosmobiology.
Milky Way the galaxy of which our solar system is a part. See also Galaxy.
minor planets Synonymous with inner planets; those planets whose orbits lie between the Sun and Asteroid Belt. See inner planets.
movable signs An alternate term for cardinal signs. See cardinal signs.
multiple conjunction A planetary arrangement in which three or more planets form a series of conjunctions that may extend from one sign into another. A member of a multiple conjunction is influenced by aspects to other members (aspect by association) even if the orb is too wide to normally include that planet. Also called a stellium. See also stellium.
mundane aspects Aspects by house rather than by degree. For example, a mundane sextile from a planet on the cusp of the second house to one on the cusp of the fourth might be less or more than the 60° required for a zodiacal sextile depending upon the size of the houses.
mundane astrology That branch of astrology that deals with world events and universal trends rather than the individual.
mutable signs Gemini, Virgo, Sagittarius and Pisces, all of which express adaptability and flexibility to some degree. They are associated naturally with cadent house; the third, sixth, ninth and twelfth, respectively. Synonymous with common signs.
mute signs the water signs; Cancer, Scorpio and Pisces, so-called because they are traditionally depicted as mute creatures: the crab, the scorpion and the fish, respectively. They are often associated with communication difficulties.
mutilated degrees So designated because of the ancient belief that if the Ascendant, chart ruler or Moon occupied any of these degrees, lameness was indicated. Sometimes referred to as lame degrees, they are: 6°-10° Taurus, 9°-15° Cancer, 18°-28° Leo, 18°-19° Scorpio, 1°, 7°, 8°, 18° and 19° in Sagittarius, 26°-29° Capricorn, and 18°-19° Aquarius.
mutual application Said of two planets moving toward each other, one direct and the other retrograde.
mutual reception Two planets placed in each other's sign of essential dignity are in mutual reception, "en rapport". Mutual reception provides a harmonious link between planets not in aspect and strengthens the aspect if one exists.
nadir The point in the celestial sphere directly opposite the zenith; the point directly beneath an observer on Earth; the low point.
Naibod arc Mean daily motion of the sun, 59' 08"; used to progress a natal horoscope by assuming one Naibod arc equals one year of life, according to the method introduced by Johann Naibod, sixteenth century astrologer and mathematician. See also solar arc.

natural chart A chart with 0° Aries on the cusp of the first house that shows the natural horoscope position of signs. Also called a flat chart.
navamsas From Hindu astrology, a ninefold division of each sign into 3 1/3° segments, each segment influenced by a sign of the zodiac. The first navamsa of Aries is sub-ruled by Aries, the next by Taurus, and so on, continuing the natural order of the zodiac through the ninth navamsa of Pisces, sub-ruled by Pisces. These "signs within a sign" create variations in interpretation of different degrees of a particular sign.
negative signs Earth and water signs; an alternate term used to describe "feminine" characteristics of receptivity and passivity. See also feminine signs.
new Moon Lunation; the beginning of a lunation cycle and of the waxing phase. Moon conjunct Sun.
nocturnal From the Latin nocturnus, of night. Refers to the lower (northern) hemisphere of a horoscope, the "night" section, that part of the heavens that falls below Earth's horizon.
nocturnal arc The time expressed in right ascension that it takes a planet or degree of the zodiac to move from its setting point on the horizon to its rising point.

nodal chart An equal house chart, which places the Moon's South Node at the Ascendant, used primarily by medical astrologers to diagnose health problems. In this context, the South Node and Ascendant represent the head, the North Node and Decendant the feet, the lower hemisphere the right side of the body and the upper hemisphere the left.
node The point of intersection of a planet's orbit and the ecliptic.
nonagesimal The point 90° from the Ascendant. The highest point of the ecliptic above the horizon.
nonile A ninth harmonic aspect based on division of 360° by 9 (40°). A minor aspect, the nonile is seldom used by modern astrologers. It was once given a fatalistic connotation.

occidental houses Correctly, houses that lie in the western (occidental) portion of a horoscope, houses four through nine. Sometimes used to describe first and third quadrant houses (one, two, three, seven, eight and nine), those houses that are moving away from the vertical axis toward the horizon (in a clockwise direction in a horoscope).
occultation From the Latin occultatio, a hiding; an eclipse of a planet. The term eclipse is usually applied to an occultation that hides the Sun or Moon from Earth's view; occultation describes eclipses that obstruct Earth's view of planets other than the Sun or Moon. The eclipsing planet is emphasized over the occulted (hidden) planet in interpreting the accompanying conjunction between the two planets forming an occultation.
opposition A second harmonic aspect, separating distance 180°. a major hard aspect, the opposition creates awareness, attraction and antagonism between the planets in polarity.
orb The number of degrees by which an aspect may vary from partile (exactness) and remain effective.
orbit The path a heavenly body follows as it travels around another stellar body.
oriental Literally eastern; said of a planet that rises and sets before the Sun. The oriental planet, called the leading planet, is the one that will rise immediately before the Sun; i.e., the planet that directly precedes the Sun clockwise (behind the Sun in the natural order of the zodiac).
oriental houses Houses that lie in the eastern (oriental) hemisphere of a horoscope, houses one, two, three, ten, eleven, and twelve. Sometimes used to describe those houses moving away (clockwise) from the horizon (Ascendant-Decendant axis) and toward the vertical axis (meridian axis, MC-IC axis), the second and fourth quadrant houses, namely houses four, five, six, ten, eleven and twelve.
outer houses Those planets whose orbits fall outside the Asteroid Belt; also called major planets because of their larger orbits. See also major planets.

partile The degree at which an aspect is precisely exact (0° orb). An aspect that is within 1° orb is said to be exact but not partile.
Part of Fortune The Arabian Part most commonly used by western astrologers. Calculated by subtracting the Sun's position from the sum of the Ascendant's and Moon's positions, the degree occupied by the Part of Fortune symbolizes good fortune. Also called Fortuna and Pars Fortunæ. See also Fortuna, Arabian Parts.
penumbra Literally partial shadow; the partially lighted area around any completely darkened area (umbra) of full shadow.
penumbral eclipse The term applied when the Moon passes through Earth's penumbra; the shadow does not obliterate the Moon form Earth's view but causes it to appear orangish or copper-colored.
peregrine From the Latin peregrinus, foreigner. Said of a planet that does not occupy a sign of essential dignity or debilitation and is not in mutual reception with any other planet. A peregrine planet is said to drift aimlessly and lack standing in the horoscope; its action depends upon planets with which it is aspected.
perigee The point of orbit at which a planet is closest to Earth.
perihelion The point in a planet's orbit that lies closest to the Sun.
periodical lunation Term applied to the transiting Moon's monthly return to the exact position occupied in a natal horoscope. See also lunar period.

Placidean houses The house system devised by the Spanish monk, Placidus de Tito (seventeenth century). Placidus' system, still widely used today, is based on the trisection of nocturnal and diurnal semi-arcs. The time it takes from each degree of the ecliptic to rise from the lower meridian to the horizon (nocturnal semi-arc) and to rise from the horizon to the upper meridian (diurnal semi-arc) is adapted to space.
planet From the Greek planetes, wanderer; used astrologically to describe any heavenly body which when viewed from Earth appears to move, as distinguished from fixed stars.
planetary hours A system devised by ancient astrologers that assigned one of the seven planets then known to each hour of the day. The first hour of sunrise was ruled by the planetary day ruler (Sunday, Sun; Monday, Moon; Tuesday, Mars; Wednesday, Mercury; Thursday, Jupiter; Friday, Venus; Saturday, Saturn) and each hour thereafter governed by the next faster moving planet in rotation from Saturn to Jupiter, Mars, Sun, Venus, Mercury, Moon and back to Saturn throughout the twenty-four-hour period. Planetary energy was thought to be focused during the days and hours associated with a planet.
planetary node The point at which a planet's path intersects the ecliptic; declination, 0°. The term is usually reserved for nodes other than the Moon's Nodes.
planetary patterns Used interchangeably with shaping. Sometimes equated with aspect patterns. See also shaping, Bowl, Bucket, Bundle, Locomotive, See-Saw, Splash, Splay.
platic Term used to describe any aspect that is not exact (within 1° orb) but within allowable orb.

Pleiades A group of fixed stars in the constellation Taurus. They are called the "Weeping Sisters" because, according to Greek mythology, seven sisters, Alcyone, Merope, Celæno, Taygeta, Maia, Electra and Sterope, daughters of Atlas and the nymph Pleione, killed themselves for grief when Atlas was transformed into a mountain. According to a different version, Jupiter transformed the sisters into stars so they could escape the attentions of Orion. The largest star in the group is Alcyone at about 29° Taurus.
polarity The contrasting and complementary qualities shown by signs opposite each other in the zodiac.
pole Either end of the axis of any sphere such as the Earth, the celestial sphere, etc.

precession of the equinoxes The gradual westward shift (about 50" each year) of the equinoctial points along the ecliptic due to the ecliptic due to the rotational movement of the poles of Earth's axis. This phenomena creates an increasing difference in the tropical (based upon the ecliptic and the Sun's ingress into the sing Aries) and the sidereal zodiacs (based upon constellations) or about 50" each year. See also ayanamsa, equinox, precession, Tropical zodiac, sidereal zodiac.
prenatal epoch The astrological moment of conception. According to Ptolemy, the natal Ascendant or Descendant coincides with the Moon's zodiacal position at the prenatal epoch, ten lunar months prior to birth, more or less; used primarily in chart rectification.

Ptolemy, Claudius A great astrologer, astronomer and geographer of the second century (ca. 100-178 A.D.) who developed the theory that Earth is the motionless center of the universe about which the planets, sun and Moon revolve. Ptolemy's work, recorded in his Tetrabiblos, was based in part upon the earlier works of Hipparchus (ca. 190-120 B.C.), who catalogued the known stars and, through his observations, discovered Precession of the Equinoxes. The Ptolmaic theory was widely accepted until replaced by the Copernican theory, put forth in the sixteenth century, which states that Earth is a moving planet, thus laying the foundation for later discoveries.
