☉ Sun □ Square ♂ Mars
90° · major aspect · tense · default orb ±7°
A square between Sun and Mars sets the source of vitality and honor at friction with the planet of heat, force, and aggression, both in signs of one modality, an angle Ptolemy called inharmonious. The tradition reads the Sun's dignity and life-force provoked by Martial fire, producing a temperament of great energy under tension, courage that risks rashness, and force pressed against authority. Older sources tie the pairing to conflict, contention, and the danger of fevers and wounds, Mars afflicting the Sun's significations of the heart and the vital spirit. The combination is associated in classical texts with combative drive and the friction between will and impulse.
Traditional reading
The Sun belongs to the diurnal sect and Mars to the nocturnal, so authors read the square as harshest when Mars operates out of sect by day, where his malefic heat is least restrained near the Sun's light. Mars, the faster of the two, applies to the Sun and forms the figure, though a body within about fifteen degrees of the Sun was also read as combust, a separate affliction the tradition tracked. Reception softens the friction where the Sun sits in Aries or Scorpio, Mars's houses, or Mars in Leo. Older writers counted Sun-Mars squares among the significators of strife.
Classical reading
Ptolemy classifies the square (quartile) as inharmonious, formed by signs of the same modality. Described as friction or productive tension.
Modern reading
Modern reading: creative tension. The two bodies push against each other, generating energy that demands resolution.
