Thomas B. Costain birth chart is shown with zodiac signs and aspects. Because the birth time is unknown, Arcadia does not use houses, Rising sign, or angular dominants as the main basis of interpretation.
Thomas B. Costain's chart rests first on the stable factors: Sun in Taurus and Moon in Pisces. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mercury conjunct Mars (orb 3°) gives a central dynamic in this reading. The orb is tight enough to count in the main reading.
In plain terms, this aspect makes thought move fast into speech, action, or argument.
The birth time is not known with certainty, so the Rising sign and houses are less reliable. Signs and exact aspects give the safer reading base.

Signs Mars in Aries · Venus in Taurus
Aspects Venus conjunct Neptune (orb 3.8°) · Jupiter square Pluto (orb 5.1°)
This section gives a concrete reading thread. It highlights the most visible signatures, then the tabs keep each placement separate instead of mixing everything together.
Important: Unknown birth time: the Rising sign, houses, and angular dominants are too time-sensitive to anchor the interpretation. The Moon remains useful, but its exact aspects can shift during the day: tight non-Moon aspects are more reliable when they exist.
Start here: a short reading that shows what hooks, what helps, what pushes back, and where it becomes concrete.
Sun in Taurus · Moon in Pisces
First hook: this is where the chart often becomes recognizable in real life. Sun in Taurus: identity and direction move through nature, good food, physical sensuality, roots, resources, and perseverance; Moon in Pisces: emotional safety looks for imagination, faith, compassion, dream, and permeability. Because the birth time is missing, reliable aspects should carry the next step before houses or angles.
Dominants unavailable without reliable birth time
Angular dominants depend on birth time. Without a reliable hour, do not use them as primary evidence.
Harmonious circuit: Moon, Mars, Jupiter, Mercury, and Saturn
This is the easiest door into the chart: it shows what tends to cooperate naturally.
This pattern describes what comes more easily. Houses are not used here: unknown time. It connects Moon (emotional needs, instinct, and inner safety), Mars (action, anger, desire, and courage), Jupiter (growth, faith, luck, and confidence in the future), and Mercury (thinking, speech, and decisions).
This is the clearest cooperation pattern in the chart: Moon sextile Mars (orb 1°), Moon sextile Mercury (orb 1.9°), and Mars trine Jupiter (orb 3.5°). It shows where functions support each other, recover, or come naturally when used together. Because several planets are connected, the full pattern matters more than one isolated aspect.
Tension circuit: Moon, Jupiter, Pluto, and Neptune
This is the pressure line to read first: it shows where tension repeats in concrete situations.
This pattern shows where pressure builds fastest. Houses are not used here: unknown time. It connects Moon (emotional needs, instinct, and inner safety), Jupiter (growth, faith, luck, and confidence in the future), Pluto (power, crisis, intensity, and deep transformation), and Neptune (dreams, ideals, imagination, and confusion).
This is the clearest friction pattern in the chart: Moon square Pluto (orb 0.5°), Jupiter square Neptune (orb 3.4°), and Moon opposite Jupiter (orb 4.6°). It shows where pressure, contradiction, or repeated effort concentrates. Because several planets are connected, the full pattern matters more than one isolated aspect.
Houses unavailable without reliable birth time
Houses describe domains of existence, but they depend on birth time. Without a reliable hour, signs and aspects should carry the reading.

Without a reliable birth time, the Sun, Moon, and exact aspects become the reliable base. The Rising sign, houses, and angular dominants need a reliable birth time.
The Moon can change signs during a day. Near a lunar sign change, the Moon sign remains a hypothesis.
Without a reliable hour, exact aspects and reliable repetitions can strongly nuance the starting reading.
Sun in Taurus remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Taurus style: nature, good food, physical sensuality, roots, resources, and perseverance.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Sun conjunct Venus (orb 1°). Aspect effect: brings identity, ego, father image, desire, taste, and attraction together: the person wants to be seen through what they love or embody.
Sun conjunct Venus (orb 1°) brings the two planets out together. The orb is extremely tight; this aspect is one of the chart's strongest signals.
Here, both planets use the same Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance). Sun in Taurus brings identity, ego, father figure, visibility, and direction; Venus in Taurus brings desire, taste, relationship, and attraction.
Concrete effect: this aspect brings identity, ego, father image, desire, taste, and attraction together: the person wants to be seen through what they love or embody.
Reading note: Common solar conjunction: Mercury and Venus always stay close to the Sun. It becomes genuinely meaningful when the orb is very tight, one factor is angular, or the same theme repeats elsewhere.
Sun conjunct Neptune (orb 4.8°) brings the two planets out together. The orb is moderate; it stays secondary beside tighter signatures.
Here, both planets use the same Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance). Sun in Taurus brings identity, ego, father figure, visibility, and direction; Neptune in Taurus brings imagination, image, popularity, collective moods, and inspiration.
Concrete effect: this aspect ties identity to image, dream, inspiration, and popularity.
Moon in Pisces remains a useful base without a birth time. The Moon sign is often usable, but near a Moon sign change it remains a hypothesis; the Moon describes personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm, with Pisces style: imagination, faith, compassion, dream, and permeability.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Pisces style (imagination, faith, compassion, dream, and permeability). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon square Pluto (orb 0.5°). Aspect effect: creates tension between personal dream, childhood, mother image, control, and fear: protection can become suspicion, grip, or overreaction.
Time-sensitive Moon aspect: Moon square Pluto (orb 0.5°). Because the birth time is unknown, the Moon's exact degree can shift during the day. This interpretation stays provisional and gains weight only if the aspect remains tight across the possible birth window or repeats another clear signature.
Here, Moon in Pisces brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Pisces style (imagination, faith, compassion, dream, and permeability); Pluto in Gemini brings crisis, power, survival, and regeneration with Gemini style (curiosity, language, movement, and mental adaptation).
Concrete friction: this aspect creates tension between personal dream, childhood, mother image, control, and fear: protection can become suspicion, grip, or overreaction.
Time-sensitive Moon aspect: Moon sextile Mars (orb 1°). Because the birth time is unknown, the Moon's exact degree can shift during the day. This interpretation stays provisional and gains weight only if the aspect remains tight across the possible birth window or repeats another clear signature.
