Thom Mayne 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.
Thom Mayne's chart rests first on the stable factors: Sun in Capricorn and Moon in Scorpio. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mars conjunct Uranus (orb 0.3°) gives a central dynamic in this reading. The orb is extremely tight; this aspect is one of the chart's strongest signals.
In plain terms, this aspect combines action, speed, risk, rupture, and refusal to be controlled.
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 Sun in Capricorn · Mars in Gemini
Aspects Venus opposite Saturn (orb 1.1°) · Sun trine Mars (orb 7.1°)
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 Capricorn · Moon in Scorpio
First hook: this is where the chart often becomes recognizable in real life. Sun in Capricorn: identity and direction move through structure, ambition, responsibility, and long construction; Moon in Scorpio: emotional safety looks for intensity, desire, crisis, secrecy, and invisible power. 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: Mars, Neptune, Pluto, and Sun
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 Mars (action, anger, desire, and courage), Neptune (dreams, ideals, imagination, and confusion), Pluto (power, crisis, intensity, and deep transformation), and Sun (identity, confidence, and direction).
This is the clearest cooperation pattern in the chart: Mars trine Neptune (orb 1.2°), Mars sextile Pluto (orb 2.4°), and Sun trine Neptune (orb 5.9°). 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 link: Venus and Saturn
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 Venus (attraction, pleasure, taste, and relationships) and Saturn (responsibility, limits, effort, and patience).
This is the clearest friction pattern in the chart: Venus opposite Saturn (orb 1.1°). It shows where pressure, contradiction, or repeated effort concentrates. No wider group outranks this link, so read it as a strong but isolated signal.
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 Capricorn remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Capricorn style: structure, ambition, responsibility, and long construction.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Capricorn style (structure, ambition, responsibility, and long construction). Exact aspects and repeated patterns indicate whether this theme becomes central.
Sun trine Neptune (orb 5.9°) shows positive structural ease between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Concrete support: this aspect gives positive ease embodying an inspiring or popular image. Father-image layer: ego, personal direction, and the father imprint are supported by Neptune.
Moon in Scorpio 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 Scorpio style: intensity, desire, crisis, secrecy, and invisible power.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Scorpio style (intensity, desire, crisis, secrecy, and invisible power). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon square Pluto (orb 0.4°). 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 0.4°). 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 Scorpio brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Pluto in Leo brings crisis, power, survival, and regeneration with Leo style (presence, pride, creation, and the wish to be seen).
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 Mercury (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 Scorpio brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Scorpio style (intensity, desire, crisis, secrecy, and invisible power); Mercury in Capricorn brings intellect, language, thought, and technique with Capricorn style (structure, ambition, responsibility, and long construction).
Concrete cooperation: personal dream and intellect can cooperate when words give a living form to the inner image. Mother-image layer: childhood, mother image, and inner child can cooperate with Mercury.
The Rising sign cannot be determined if the time is not known.
Mercury in Capricorn remains a reliable combination even without a birth time. Mercury describes intellect, language, thought, and technique, with Capricorn style: structure, ambition, responsibility, and long construction.
Concretely, the person expresses thinking, speech, learning, technique, and mental strategy through the Capricorn style (structure, ambition, responsibility, and long construction). Exact aspects and repeated patterns indicate whether this theme becomes central.
Same aspect, other side: the full reading is under the other planet, and it also applies to Mercury.
Mercury square Neptune (orb 4.5°) creates concrete friction between the two planets. The orb is moderate; it stays secondary beside tighter signatures.
Concrete friction: this aspect creates tension between analysis, language, confusion, ideal, and collective perception.
Venus in Sagittarius remains a reliable combination even without a birth time. Venus describes desire, taste, relationship, and attraction, with Sagittarius style: expansion, travel, belief, and the search for meaning.
Concretely, the person expresses desire, taste, attraction, pleasure, and love style through the Sagittarius style (expansion, travel, belief, and the search for meaning). Exact aspects and repeated patterns indicate whether this theme becomes central.
