Almuten

The planet of chief influence in a Nativity by virtue of essential and accidental dignities. Its strength is estimated from: its intrinsic character; its Sign position where posited, its own Sign, or the Sign in which it is in exaltation; its harmonious aspects from favoring planets; and its elevated position in a geoarc Figure. A term of Arabian origin, seldom employed by present day astrologers.
