The Sun in Leo is in domicile, the planet's own home, and the tradition lists no other planet's rulership here. Leo is a masculine, fixed fire sign; the Sun is a masculine, day-team planet, so sect, gender and sign agree.
Leo is the fifth sign of the zodiac, a fixed fire sign with positive polarity, and the only sign the Sun governs in traditional astrology.

The Moon in Leo is in the Sun's home sign, a masculine, fixed fire sign. The tradition lists no domicile, exaltation, detriment or fall for the Moon there.
Leo is a fixed fire sign with positive polarity, the sign the Sun governs, and a Moon there sits in the Sun's home. Modern psychological astrology reads the emotional need here as warmth returned: to be noticed, appreciated and welcomed.

Your Ascendant is in Aries when Aries is the sign crossing the eastern horizon at birth. The Ascendant changes sign about every two hours, so birth time decides it. In whole-sign houses, the system Hellenistic astrologers used, each sign is one house, so Aries is your first house. Its domicile lord, the planet that rules the sign, is Mars. Mars becomes the lord of the Ascendant, one of the planets the tradition weighs for the chart as a whole. Mars also rules Scorpio, which would fall in your eighth house, and is exalted in Capricorn, your tenth. Aries is a masculine, cardinal fire sign and the Sun's exaltation, so a chart with Aries rising has the Sun's honored sign on its horizon. The tradition asks where Mars is, by sign and house, and what dignity it holds there.

Reviewer's notes
Dignities, houses counts, genders and modalities matched the project's own dignity tables and Ptolemy/Valens. Lord-of-the-Ascendant importance confirmed only in secondary sources (Astrology Podcast); softened 'first/main' to 'among the first/key'.

1 Oct 2026
With Aries rising, Aries was crossing the eastern horizon at the moment of birth. The Ascendant, or rising sign, changes about every two hours, so it depends on birth time and place. Modern psychological astrology reads it as a manner of entering situations, not as the core self. For Aries, a cardinal fire sign, authors describe a direct, quick and forward approach, with a first impression of decisiveness. The tension they name is acting before reading the room. Hellenistic astrologers treat the Ascendant as the starting point of the chart. They read it through the condition of its lord, Mars for Aries, with less attention to a style of manner. The modern reading describes behavior; the Hellenistic one describes technique.

Reviewer's notes
Element, modality, ruler and Ascendant-concept claims confirmed in secondary references; the per-sign manner descriptions attributed to modern authors are tradition-level and not checked against Arroyo or Sasportas text. Softened "not through a style of manner" to "less attention", since Hellenistic authors also described temperament and appearance by sign.
