Mark Blyth 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.
Mark Blyth's chart rests first on the stable factors: Sun in Libra and Moon in Leo. Without a reliable time, signs and aspects are stronger than the Rising sign or houses.
Chart detail:
Mercury opposite Lilith (orb 1.5°) gives a central dynamic in this reading. The orb is very tight; this describes a stable character pattern more than a passing reaction.
In plain terms, this aspect opposes intellect to ideal demand, obsession, or speech that refuses approximation.
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.

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 Libra · Moon in Leo
First hook: this is where the chart often becomes recognizable in real life. Sun in Libra: identity and direction move through relationship, balance, negotiation, and sense of form; Moon in Leo: emotional safety looks for presence, pride, creation, and the wish to be seen. 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, Saturn, Sun, and Mars
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), Saturn (responsibility, limits, effort, and patience), Sun (identity, confidence, and direction), and Mars (action, anger, desire, and courage).
This is the clearest cooperation pattern in the chart: Sun sextile Moon (orb 1.3°), Moon trine Saturn (orb 2.4°), and Mars trine Saturn (orb 3.8°). 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: Sun 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 Sun (identity, confidence, and direction) and Saturn (responsibility, limits, effort, and patience).
This is the clearest friction pattern in the chart: Sun opposite Saturn (orb 3.6°). 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 Libra remains a reliable combination even without a birth time. The Sun describes identity, ego, father figure, visibility, and direction, with Libra style: relationship, balance, negotiation, and sense of form.
Concretely, the person expresses identity, ego, father figure, recognition, and personal direction through the Libra style (relationship, balance, negotiation, and sense of form). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Sun sextile Moon (orb 1.3°). Aspect effect: lets identity, inner play, and personal dream cooperate when the person uses both sides together. Family-image layer: the sextile shows active cooperation between father image and mother image.
Time-sensitive Moon aspect: Sun sextile Moon (orb 1.3°). 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, Sun in Libra brings identity, ego, father figure, visibility, and direction with Libra style (relationship, balance, negotiation, and sense of form); Moon in Leo brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Leo style (presence, pride, creation, and the wish to be seen).
Concrete cooperation: identity, inner play, and personal dream can cooperate when the person uses both sides together. Family-image layer: the sextile shows active cooperation between father image and mother image.
Sun opposite Saturn (orb 3.6°) puts the two planets face to face, with visible back-and-forth or tension. The orb is moderate; it stays secondary beside tighter signatures.
Concrete conflict: this aspect sets personal direction, ego, or father image against Saturn pressure: duty, limits, fear, authority, or a demanding father image.
Moon in Leo 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 Leo style: presence, pride, creation, and the wish to be seen.
Concretely, the person expresses personal dream, play instinct, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm through the Leo style (presence, pride, creation, and the wish to be seen). Exact aspects and repeated patterns indicate whether this theme becomes central.
Aspect connected to this placement: Moon trine Saturn (orb 2.4°). Aspect effect: gives positive steadiness when personal dream, inner child, and mother image accept structure. Mother-image layer: childhood, mother image, and inner child are supported by Saturn.
Same aspect, other side: the full reading is under the other planet, and it also applies to Moon.
Time-sensitive Moon aspect: Moon trine Saturn (orb 2.4°). 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 Leo brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm with Leo style (presence, pride, creation, and the wish to be seen); Saturn in Aries brings discipline, constraint, endurance, and mastery with Aries style (initiative, speed, confrontation, and direct action).
