♂ Mars ⚼ Sesquiquadrate ♄ Saturn

135° · minor aspect · tense · default orb ±2°

The sesquiquadrate between Mars and Saturn joins the tradition's two malefics through the tense minor angle of 135 degrees. Classical doctrine reads their combination as heat against cold, haste against delay, the axe against the wall, and assigns their hard contacts to hardship, obstructed effort, and severity; the eighth-harmonic minor delivers the same testimony at lower volume, chronic grinding rather than open calamity. Domains the sources tie to the pair include labor under constraint, fortification and demolition, the chronic complaints of the medical lists, and discipline enforced. Even among minors, practitioners rank this pairing's friction heavy for its size.

Traditional reading

A strong reception cuts against the pair's grim reputation: Mars is exalted in Capricorn, Saturn's domicile, and traditional authors weigh that welcome when judging their contacts, force given structure rather than force denied. Mars is the applying body. Sect separates them, each malefic assigned to a different faction, Saturn to the day and Mars to the night, so one of the two stands contrary to sect in any chart, a severity older than the early modern aspect conveying it here. Ebertin's school, fond of the 45 and 135 degree family, filed Mars-Saturn under harmful or inhibited energy.
