Bicorporeal

July 17, 2026Astrology Encyclopediaadmin

Definition

Bicorporeal means “double-bodied.” In traditional astrology, the term generally describes the common or mutable signs: Gemini, Virgo, Sagittarius, and Pisces. These signs occupy the transition between seasons and are associated with adjustment, variation, and movement between conditions. Some traditional authorities apply the term more narrowly according to a sign’s symbolic figure, so its precise use can depend on the astrological text or method being followed.

Astrological Meaning

A bicorporeal sign can suggest multiplicity, flexibility, divided attention, or the ability to respond to changing circumstances. In a natal chart, a strong emphasis on these signs may indicate adaptability and an interest in connecting different ideas, roles, or environments. It does not automatically imply indecision; the condition of the sign’s ruling planet and the relevant house provide essential context. In horary and electional astrology, bicorporeal signs may describe situations involving more than one person, option, stage, or outcome, but the full chart must support that interpretation.

Why It Matters

Recognizing bicorporeal signs helps clarify traditional chart language and adds nuance to questions about stability, change, and complexity. The classification is especially useful when comparing cardinal, fixed, and mutable modes or assessing whether a matter is likely to remain singular or develop multiple parts. Because historical definitions vary, astrologers benefit from applying the term consistently within their chosen tradition.

Civil Day

July 17, 2026Astrology Encyclopediaadmin

Definition

A civil day is the standard 24-hour calendar period used for public timekeeping, beginning at midnight and ending at the following midnight. It is based on local civil time rather than the exact visible motion of the Sun. Time zones, daylight-saving rules, and calendar conventions determine how a civil day is recorded in a particular place.

Astrological Meaning

In astrology, the civil day provides the practical framework for recording a birth or event date and time. Astrologers convert this information as needed—often into Universal Time—before calculating planetary positions, house cusps, and angles. The term is especially relevant when working with historical records, traditional texts, or software settings because older astronomical conventions sometimes began the day at noon, while some cultural calendars used sunset or sunrise. A civil date must therefore be interpreted together with its location and local time standard.

Why It Matters

Correctly identifying the civil day helps prevent calculation errors near midnight, during daylight-saving transitions, or when converting between time zones. A mistaken date can alter the Moon’s position and may substantially change the Ascendant, Midheaven, and house placements. Understanding the distinction between civil, solar, and astronomical time also makes older chart data easier to evaluate. The civil day does not carry an independent symbolic interpretation; its importance lies in establishing an accurate temporal foundation for a natal chart or event chart.

Bi-Quintile v

July 17, 2026Astrology Encyclopediaadmin

Definition

Bi-Quintile v refers to the bi-quintile, an astrological aspect formed when two planets or chart points are approximately 144 degrees apart. It belongs to the fifth-harmonic family, along with the 72-degree quintile. Astrologers generally use a narrow orb for this minor aspect because its influence is considered more precise than that of major aspects.

Astrological Meaning

The bi-quintile is commonly associated with creativity, specialized ability, pattern recognition, and the deliberate shaping of ideas or materials. Its two planets describe the functions being combined. For example, a Mercury–Saturn bi-quintile may suggest skill in organizing thought, while a Venus–Uranus bi-quintile may indicate an inventive aesthetic sense. Sign, house, dignity, and the rest of the chart determine how readily the potential is expressed.

Why It Matters

This aspect can reveal an understated capacity that may not be obvious when only conjunctions, squares, trines, sextiles, and oppositions are considered. It does not guarantee talent or achievement; rather, it may point to an unusual way of integrating two planetary principles. Repetition of quintile-family aspects can make fifth-harmonic themes more prominent. In interpretation, the bi-quintile is most useful as supporting evidence within the natal chart, not as a stand-alone judgment.

Decreasing or Increasing in Light

July 17, 2026Astrology Encyclopediaadmin

Definition

Decreasing or Increasing in Light is a traditional astrological condition describing whether a celestial body’s visible illumination is diminishing or growing. It is most clearly applied to the Moon: the Moon increases in light while waxing from the New Moon toward the Full Moon and decreases in light while waning from the Full Moon toward the next New Moon. Classical authors also assessed planetary light through solar phase and visibility, although exact rules can vary by planet and tradition.

Astrological Meaning

Increasing light is commonly associated with development, accumulation, emergence, and matters moving toward fuller expression. Decreasing light may suggest release, consolidation, withdrawal, completion, or a turn toward inward activity. These qualities do not automatically make a planet fortunate or unfortunate. They describe a phase within a cycle and must be considered alongside sign, house, aspects, speed, sect, dignity, and proximity to the Sun.

Why It Matters

This distinction adds timing and context to chart interpretation. A waxing Moon may emphasize building momentum or making something more visible, while a waning Moon may support reflection, refinement, or bringing an existing process to a close. In natal astrology, the condition can describe a person’s characteristic way of engaging with growth and completion. In electional and horary astrology, it may help assess whether a matter is increasing, peaking, or diminishing, but it should never be treated as a stand-alone verdict.

Birth Stones v

July 17, 2026Astrology Encyclopediaadmin

Definition

Birth stones are gemstones associated with a person’s birth month, zodiac sign, planetary ruler, or, in some traditions, day of the week. The associations vary across cultures and historical periods, so there is no single universal list. The final “v” in this title is not a standard astrological symbol and may simply distinguish this entry from another version or classification.

Astrological Meaning

In astrological practice, a birth stone may serve as a symbolic link to a sign or planet. Ruby, for example, is often connected with the Sun, while emerald is commonly associated with Mercury or Venus, depending on the system being used. Some astrologers select stones through the natal chart rather than the birth month alone, considering factors such as the Ascendant, planetary dignities, or an emphasized element. These correspondences are interpretive traditions, not fixed rules or guaranteed sources of influence.

Why It Matters

Birth stones offer a tangible way to engage with astrological symbolism through jewelry, meditation, ritual, or personal reflection. They can help someone explore the qualities traditionally assigned to a planet or sign, but they should be interpreted within a clearly identified correspondence system. Comparing the stone’s symbolism with the full natal chart usually provides more context than relying on a commercial month-by-month list. Personal preference, cultural meaning, and ethical sourcing may also guide the choice.

Decumbiture

July 17, 2026Astrology Encyclopediaadmin

Definition

Decumbiture is a traditional astrological chart cast for the time and place when an illness begins, becomes clearly recognizable, or causes a person to take to bed. The term comes from a Latin root associated with lying down. Unlike a natal chart, it describes a particular episode rather than the pattern of an entire life.

Astrological Meaning

In classical medical astrology, the decumbiture chart was interpreted to explore the character and possible course of an illness. Practitioners commonly considered the Ascendant and its ruler as significators of the patient, while the sixth house and its ruler represented illness. The Moon’s condition, planetary aspects, house rulerships, and the relative strength of benefic and malefic planets added context. Different traditions used varying rules, especially when choosing between the first symptoms, a formal diagnosis, or the moment the patient became bedridden as the chart’s starting time.

Why It Matters

Decumbiture illustrates how traditional astrology applied event-chart techniques to health-related questions. Today, it is primarily valuable for studying historical practice and classical chart interpretation. Because its symbolism cannot establish a diagnosis or replace evidence-based care, any modern use should remain reflective and supplementary, with health concerns directed to qualified medical professionals.
