Saturn is the greater malefic of traditional astrology and the significator of duty, rules, land and buildings, old age, endurance and limits. Combust, its matters are read as out of sight rather than gone: obligations continue, but inspections, permits and approvals slow down, and older people and those in authority are harder to reach. The cazimi is counted as Saturn at its most constructive, a day for commitments meant to last.
The Sun and Saturn are old opposites in the dignity scheme. Saturn rules the two signs opposite the Sun's and the Moon's, and each is exalted where the other falls: the Sun in Aries, Saturn in Libra. So a conjunction in Aries, as in 2026 and 2027, pairs an exalted Sun with Saturn in its fall.
