In astrology, Antiscia are pairs of zodiac positions that mirror one another across the Cancer–Capricorn solstitial axis. Two positions in antiscia are located at equal distances from the solstitial points and were traditionally understood as sharing a hidden or reflected relationship. Astrologers may examine antiscia between planets, angles, or other chart factors as an additional form of structural connection within a natal chart. The technique has historical roots in traditional astrology and is generally used as a supplementary interpretive method alongside more familiar relationships such as aspects.
