♂ Mars ⚺ Semisextile ♃ Jupiter
30° · minor aspect · neutral · default orb ±2°
Mars semisextile Jupiter relates the significator of force, courage, and contest to the significator of expansion, law, and fortune across adjacent signs. The tradition assigns Mars to soldiers, iron, and strife, and Jupiter to judges, faith, and increase; joined at thirty degrees, the combination is read as enterprise and appetite operating on parallel tracks that touch only at the margin. Sources point to domains such as litigation and advocacy, campaigns of expansion, competitive zeal moderated by principle, and the administrative side of martial undertakings, all expressed in the muted register the minor aspect allows.
Traditional reading
Under Hellenistic doctrine the two planets in adjacent signs would be in aversion, and a benefic and malefic that cannot behold each other were simply held apart; the semisextile as a working angle belongs to later European practice. Sect adds texture: Jupiter belongs to the diurnal team and Mars to the nocturnal, so the pair never share a sect allegiance. Mars, the swifter of the two, is the applying body, and modern practitioners describe the figure as initiative making small recurring adjustments toward opportunity.
Classical reading
Adjacent-sign aspect (30°). Classical sources treat it as minor and somewhat dissonant due to lack of shared element or modality.
Modern reading
Modern reading: subtle adjustment. Two principles in adjacent signs requiring small course corrections to integrate.
