☉ Sun ⚼ Sesquiquadrate ♂ Mars
135° · minor aspect · tense · default orb ±2°
The sesquiquadrate joining Sun and Mars runs the classical significations of vitality and command against those of heat, iron, and severance at 135 degrees, a minor hard angle unknown to Ptolemy and formalized in the Kepler era. Where the square between these bodies was read as open contention, the eighth-harmonic version is described as lower-grade abrasion: impatience of authority, energy discharged in flares, quarrels over precedence. Sources that use the aspect assign the pair domains of soldiery, athletics, fevers and inflammations in the medical correspondences, and the recurring friction of ambition with temper.
Traditional reading
The Sun, quicker than Mars, is the applying body in this contact. Sect doctrine, older than the aspect itself, gives the pair an uneasy footing: Mars is the malefic of the nocturnal sect, and traditional authors held him most troublesome in day charts, a nuance some modern traditionalists carry over to minor hard angles. Cosmobiologists in the Ebertin line treated Sun-Mars eighth-harmonic contacts as significant markers of strained effort, ranking the 45 and 135 degree family nearly with the square, while horary practice largely ignores them altogether.
Classical reading
One and a half squares (135°). Classified as inharmonious. Adds friction similar to the semisquare.
Modern reading
Modern reading: agitating tension late in a developmental cycle. Pressure to express or resolve.
