S

Sabian Symbols

System of interpreting each of the 360 zodiacal degrees, devised by Marc Edmund Jones and Elsie Wheeler in the 1920's, then modified by Dane Rudhyar.

Sacred Geometry

Process of constructing symbolic, geometric structures via numerical relationships, whether in art, buildings, landscaping or other formal systems. The aim is to create and channel flows of beneficial energy from the subtle world into our personal and social energetic fields, or auras. These fields govern and dynamise our lives, bodies, emotions, minds, and social interaction.

Sade Sati

In Vedic Astrology, the transit of Saturn (Shani) over one's natal Moon. This technically begins 45° before the actual conjunction and releases 45° afterwards. The process takes approximately 7½ years and can present a particularly stressful period.

Sagittarius

The ninth sign of the zodiac. Mutable and fiery. Ruled by Jupiter. Emblem: The Archer, or Centaur. More about Sagittarius.

Samhain

One of the Cross-quarter days, now generally celebrated as Halloween. More about Samhain.

Sanguine Humour

Corresponding to the Air Element, according to Culpeper it "nourishes the judgement". The Sanguine Humour is able to encompass the other three humours, so when the body is is a state of health, there is no way of distinguishing between them (as they are all in a balanced state within the bloodstream). Ruled by Jupiter, its seat is the Liver and it works through the Blood. See Humours. More about the Sanguine Humour.

Saros Cycle

The cycle of eclipses, discovered by the ancient Chaldeans, lasting a little over 18 years, when Lunar Eclipses seem to repeat themselves. The cycle is also applicable to Solar Eclipses. A full Saros Series lasts some 13 centuries, due to the movement of the lunar nodes.

Satellite

An attendant body revolving around a larger one, its primary. The Moon is a satellite of the Earth, but for historical reasons is called in astrology a planet (wanderer), as is the Sun. Astronomically, all planets and other celestial bodies in our solar system are satellites of the Sun.

Satellitium

A group of three or more planets occupying a particular area of a chart having a significant effect comparable with the conjunction of all the planets concerned, even though outer members of the group would be normally considered out of orb with each other. Also called a stellium, or "satellium" (by the classically challenged...).

Saturn

The planet symbolising matters to do with karma, responsibility, structure, restriction, chronic conditions, old age and so on. Ruler of Capricorn and Aquarius. Exalted in Libra; rejoices in Aquarius. Traditionally known as the greater malefic, or infortune. More about Saturn.

Saturn Return

The return of Saturn by transit to the conjunction with natal Saturn in a horoscope. A twenty-nine year cycle, representing a period (often over many months) when we feel frustrated, angry, sad, confused, tired and insecure, it is a time when we become aware that we must accept responsibility for our actions. The first Saturn Return begins at approx. 29 years of age, the second at 58, the third at 87. More about the Saturn Return.

Scorpio

The eighth sign of the zodiac. Scorpio, the Scorpion, is a Fixed Water sign. It is traditionally ruled by Mars, but many modern astrologers have designated Pluto (discovered in 1930) as its co-ruler, or even, controversially, as its sole ruler. More about Scorpio.

Scout Planet

Last planet to rise before the Sun. See Planet of Oriental Appearance.

Secondary Progression

The progressed horoscope, based on the "day for a year" system of progressing the nativity first employed by the ancient Arabian astrologers. So called to distinguish the system from the complex method of Primary Directions. Also known as Secondary Directions. The number of days in the ephemeris are counted from the birthday as the number of years the native has been on this mortal coil, then the horoscope is calculated accordingly. This is the most widely used system of progressing the horoscope, but has some disadvantages, hence the development of both solar arc progression and of tertiary progression (q.v.).

Sect

From Hellenistic Greek: hairesis, meaning "team", "side", or "following". Traditional weighting of emphasis based on whether a birth is diurnal (sect of Helios, the Sun) or nocturnal (sect of Selene, or Moon). Sun, Jupiter and Saturn are of the diurnal sect and Moon, Venus and Mars are of the nocturnal sect. Mercury's sect is convertible, depending on weighting of orientality, gender etc. A planet in sect was considered significantly more potent than when out of sect. Sect was given very weighty consideration by the ancients, though is not generally considered by most modern astrologers. [Sect was until recently considered a measure of the hemisphere location, quadrant location, house and sign placement of all visible planets, but this view is now discredited by current translations of ancient works.]

Sedna

A newly discovered trans-neptunian planet, named after the Inuit goddess of the sea. Some 13 billion kilometres from Earth and smaller than Pluto, this "planet" has as yet no accepted astrological meaning. Discovered in 2003, it is estimated to take 10,500 years to orbit the Sun.

Selene

Greek goddess of the Moon.

Semi-arc

1. The portion of a celestial body's daily travel above the horizon between its rising and its setting is called its diurnal arc; halving this arc from horizon to midheaven or meridien gives its diurnal semi-arc. The portion below the earth is the nocturnal arc, so half of it becomes the nocturnal semi-arc. The Sun's nocturnal or diurnal semi-arc when in 0° Aries or 0° Libra, is six hours or 90° all over the Earth. At other seasons the one is greater or less than the other, according to the time of the year and the latitude of the place. The greatest discrepancy occurs where the N. or S. latitude is high, and when the Sun is in 0° Cancer or 0° Capricorn. The semi-arc is usually measured in degrees of RA passing over the Meridian; although it can be expressed in terms of time. [based on source: Encyclopedia of Astrology]
2. Term used in Primary Directions to denote the arc from a Significator to the Horizon or to the Meridian.

Semi-decile

A minor benefic aspect of 18 degrees. Also called virgintile.

Semi-quintile

Kepler's decile, a minor benefic aspect of 36 degrees.

Semi-sextile

A minor benefic aspect of 30 degrees. Some traditional astrologers do not count this as an aspect, due to the phenomenon known as Aversion.

Semi-square (semi-quadrate)

A minor adverse aspect of 45 degrees, deriving from Kepler.

Separating Aspect

See Separation.

Separation

Moving away from the partile (exact aspect). As the planet separates, the aspect becomes weaker. In Horary Astrology, it indicates events just past, or that the matter under inquiry will not eventuate.

Septile

A karmically significant aspect of just under 51°26', being 1/7^th of the zodiacal circumference.

Sesqui-quadrate (sesqui-square)

A minor adverse aspect of 135 degrees.

Seventh House

The seventh segment of an astrological chart. Known also as the Descendant, it governs marriage, business partnerships, harmony, disharmony and open enemies.

Sextile

A benefic aspect of 60 degrees.

Shadow Planet

Not a true celestial body, but a calculated point of significance in the chart, primarily the Moon's north (ascending) and south (descending) nodes. See Nodes.

Short Ascension

Signs of short ascension take less time to ascend (rise over the eastern horizon) than signs of long ascension. They are often found intercepted in charts, though not in the zodiac, as signs are never intercepted in the zodiac. Interception is neither a dignity, nor a debility. In the northern hemisphere, these are:

Capricorn Aquarius Pisces

Aries Taurus Gemini

For places in the southern hemisphere, long and short ascension are reversed. See Long Ascension.

Shabda

The cosmic sound current, or power of sound. Esoteric teachings hold that meaningful sounds and, in particular, names, have magical efficacy and can be used to create, construct or destroy phenomena, events and things. This was originally part of the ancient pantheistic or animist worldview that has become more systematised in esoteric philosophies as civilisation has developed. Alphabets such as Hebrew, Ancient Greek, and Sanskrit have in addition to their simple linguistic uses numerical and sonic values that can be harnessed and employed by adepts. Qabbala includes several systems of manipulating language and sound in this way, as do various esoteric schools in other disciplines.

Shani

Name for Saturn in Jyotish (Vedic) Astrology.

Sidereal Day

When the Earth has made one complete revolution on its axis; i.e. when the meridien has returned to its exact position after a twenty four hour period of rotation of the Earth. This is not the same as a tropical day, which is the sidereal day plus the distance travelled by the Sun in that same period, i.e. when the MC catches up with the Sun: about one degree further, or four minutes longer.

Sidereal Time

Right ascension of the meridien at mean noon (or midnight in modern ephemerides). The angular distance of the first point of Aries, or the true vernal equinox quoted in hours, minutes and seconds. Birth time is converted into sidereal time for the latitude of the birth place in order to calculate the house cusps.

Sidereal Zodiac

Zodiac based on actual positions of constellations in the heavens, as opposed to the Tropical Zodiac, which is a moveable format based on the seasons. The Tropical Zodiac defines the Vernal Point as the first degree of Aries, but the Sidereal Zodiac allows it to precess.

Significator

In Natal Astrology, the planet which rules the Ascendant. In Horary, the planet ruling the house governing the matter or person in question. In Directions, the Significator can only be Sun, Moon, Ascendant or Mid-Heaven (according to Sephariel).

Sign

A symbolic display or image that points to something not immediately evident. A sign can carry more than one, or even a range of meanings. In astrology and mythology, signs have been mapped onto constellations in the heavens, but the zodiacal signs are themselves mathematical in nature and are not directly linked to the constellations, except historically.

Signs

Twelve equal 30° divisions of the zodiac: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Signs in the Tropical Zodiac should not be confused with constellations, even though for historical reasons, they have the same names. There is no "13th Sign" of the Zodiac, as occasionally touted by skeptical astronomers, as Ophiuchus is a constellation, not a Sign. See Constellations.

Sinister Aspect

An aspect read from the left by diurnal movement, i.e. clockwise. It is thus in accordance with the natural succession of the Signs. Considered less powerful because hidden, or not in the line of sight. See Dexter.

Sirius

The Dog Star, the brightest star in the night sky. An extremely potent, binary (possibly ternary) star, Sirius is the focal point of several religions (notably the ancient Egyptian). See Fixed Stars.

Sixth House

The sixth area of an astrological chart. It is an area ruling work, health, service, helping others, subordinates, the military, professionals, daily activities and the continuous harvesting or planting of positive and negative experiences.

Slow in Course (Slow in Motion)

A planet moving slower than its Mean Motion. An accidental debility. The Moon when slow in course is considered by Bonatus in Anima Astrologicæ to be as debilitated as if she were retrograde.

Slow Signs

Signs which have the nature of Saturn and Jupiter, such as Capricorn and Aquarius, Sagittarius and Pisces.

Smoky (degrees)

Certain degrees that, according to tradition, have a moderate, or middling quality, particularly regarding appearance and character. Compare Light and Dark degrees.

Soft Aspects

A modern name for benefic aspects, sextile, trine and quintile. Soft as opposed to Hard.

Sol

The Sun, central power source of our solar system. The Sun stands for the individuality in the nativity. It rules Leo and is exalted in Aries. More about the Sun.

Solar Arc

System of progression where the distance travelled by the Sun in the progressed horoscope (calculated at a rate of 1 degree = 1 year) from its natal position is also assigned to the other planets. Hard aspects only are considered in Solar Arc theory. The advantage of this system over secondary progression is that it gives significant movement to the outer planets, thus broadening the scope for predicting major life-events.

Solar Chart

Chart based on position of Sun, either at sunrise, or noon. Useful when time of birth is unknown.

Solar Eclipse

Eclipse of the Sun. More about Eclipses

Solar Return

A chart constructed for the moment when the Sun returns to the degree and minute of its longitude at nativity (because of the Sun's irregular apparent motion, it seldom returns at the same time as birth). A solar return chart using the latitude of the present residence for construction of House Cusps indicates the course of events during the ensuing year. The transits of planets over these chart factors is used to time and date the events indicated. The solar return should be compared with the nativity and the progressed chart to make the most informed judgement.

Solar Revolution

Solar Return.

Solar System

The Sun and the family of celestial bodies which revolve around it as it journeys through space and time. It includes the known planets and their satellites, the numerous asteroids orbiting between Mars and Jupiter, plus the comets, meteoroids, the Kuiper Belt containing the icy Centaurs, the solar wind, dust, gases and radiant energies of the interplanetary medium, along with the various hypothetical planets such as Trans-Pluto (Bacchus). It is bounded at its outer extremities by the limit of the Sun's gravitational and magnetic influence (heliosphere) at a distance of approx 100 AU from the centre of the Sun. Here the solar wind meets the interstellar medium.

Solar Wind

A stream of tiny particles of gas and plasma emitted by the Sun. The speed of the solar wind is about 400 kilometres (250 miles) per second in the vicinity of Earth's orbit.

Solid Signs

Fixed Signs.

Solstice

Sol+systere, Latin for Sun and standing still. The place in the ecliptic where the Sun appears to stand still at its furthest point north or south of the equator, the first degree of Cancer or Capricorn. The northernmost point is the summer solstice and the southernmost is the winter solstice, when viewed from the northern hemisphere. The Sun at maximum declination appears to stand still at these points for about three days. The seasons are reversed in the southern hemisphere. See Tropic.

Solsticial Signs

Cancer and Capricorn. These signs hold the summer and winter solstices (shortest and longest nights). cf Equinoctial Signs.

South Node

See Dragon's Tail.

Southern Signs

Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. The Sun in these signs has a southern declination.

Spagyric

Plant alchemy, mainly for medicinal purposes.

Spagyrist

Alchemist, particularly one who sought chemical and herbal remedies for the healing of diseases.

Spear-Bearer

A term in ancient Hellenistic astrology for when one planet was seen as protecting, or acting as bodyguard for another. Not used in modern astrology.

Specialis Cycle

The 20 year cycle between conjunctions of transiting Jupiter and transiting Saturn in the heavens.

Speculum

A table of the data concerning the planets in a horoscope. Useful in calculating directions.

Speculum of Aspects

A table of every degree in a horoscope that may be in aspect with the planets. Useful for noting transiting aspects at a glance.

Spheres

Ancient astronomers, notably Aristotle, held that the Earth was the centre of the universe and that the planets and stars occupied positions in a series of concentric, crystal spheres surrounding the Earth, or in the case of the Pythagoreans, a Central Fire. See Music of the Spheres.

Spiritus Mundi

Spirit (subtle underlying power) of the World. See Quintessence.

Square

Major malefic (unfavourable) aspect of 90 degrees.

Standard Time

Time adopted in modern time zones. This is not true local or Mean Time and must be corrected according to longitude for the accurate calculation of horoscopes.

Stars

Visible as tiny points of light in the night sky, stars have been important to mankind since the dawn of consciousness. Modern physics declares that each star is an enormous nuclear fireball like our Sun – some, such as Antares, being vastly more massive than the Sun – but esoterically each star is considered to be the body of a conscious cosmic being (such as an angel, or a deva). Some visible stars of sufficient magnitude have a powerful effect on life on Earth. These "Fixed Stars" appear to be stationary, relative to the Earth, whilst "Wandering Stars" (or Planets) appear to move across the zodiac. To distinguish, Fixed Stars appear to twinkle in the sky, but Planets shine with an unwavering gleam. More on Fixed Stars.

Stationary (Station)

A planet in its station appears to be standing still between periods of Retrograde or Direct motion. Sun and Moon are never stationary. See Retrograde.

Stationary Direct

A planet stationary at the position of returning to Direct Motion through the zodiac after a period of Retrograde Motion. It is the ideal time to make or implement relevant decisions. This is considered to be among the most powerful positions for planetary influence, especially in Jyotish, or Indian (Vedic) astrology.

Stationary Retrograde

A planet stationary at the point of turning retrograde. This is an important position, as it indicates the need for rethinking the issues related to condition of the planet, its sign and house, as they will be raised in one form or another during the retrograde period.

Strictures (Against Judgement)

Certain conditions in a chart restricting its interpretation. Used mainly in Horary, strictures warn the astrologer not to proceed, as the chart is likely give faulty information. Lilly presents a number of what he calls "Considerations Before Judgement".

Stellium

See satellitium.

Succedent

Second, fifth, eighth and eleventh houses in a chart. Corresponding to the fixed signs, they lie between the cardinal angles and the cadent houses. Planets in these houses function at around 50% of their power, based on the strength of an angular placement, which is the most potent.

Sun

The Sun, central power source of our solar system, is our very own star. Known as "Sol" in Latin and "Helios" in Greek, the masculine Sun stands for the individuality in the nativity. He rules Leo and is exalted in Aries. More about the Sun.

Sun Ruler

Planetary ruler of the Sun Sign.

Sun Signs

The twelve traditional signs of the zodiac. The Sun Sign is the sign through which the Sun is passing at a given moment, such as the moment of birth.

Sunrise Chart

Chart based on the position of the Sun at sunrise on the day of birth. Useful technique in the absence of a known birthtime.

Superior Planets (Superiors)

Saturn, Jupiter and Mars are the traditional Superiors, as in the geocentric system they are above the Sun. Modern astrologers include Pluto, Neptune, Uranus, Chiron and the asteroids, also the trans-plutonian "planets" such as Trans-Pluto (Bacchus, or Persephone). Their orbits in our modern heliocentric system lie beyond that of the Earth when viewed from the Sun. The orbits of the Inferior planets lie between the Earth and the Sun (Vulcan, Moon, Mercury and Venus). See Inferior Planets.

Swift in Course (Swift in Motion)

A planet moving faster than its mean motion. An accidental dignity.

Synastry

Art of chart comparison, for analysis of relationships.

Synchronicity

The concept popularised by the analytical psychologist C. G. Jung that celestials do not have a direct causal effect on phenomena, but rather present a timed map, whereby events and characteristics that occur on Earth (marked in the horoscope) can be tracked and interpreted. Stars and planets are thought to be "in sync" or "synchronous" with these events and phenomena, even though they have no causal relationship. This idea of an "a-causal relationship" or "meaningful coincidence" is not the traditional view, but is popular among modern Western psychological astrologers, as it does not seem to require any demonstration of causal force involving action at a distance as yet unknown to physics.

Synod

Conjunction of two or more of the heavenly bodies. More of an astronomical term than an astrological one, it suggests when used by astrologers the gathering of the relevant celestials for a meeting (as in a convention of church elders).

Synodical Lunation

The time taken by the Moon from one conjunction with the Sun until the next: 29 days, 12 hours, 44 minutes and 3 seconds...

Syzygies

Refer conjunctions and oppositions.
