Fixed Stars

Places 76 fixed stars in the tropical zodiac for any date from their catalogue positions and proper motions, within 1″ of the Swiss Ephemeris, and finds those on a chart's planets and angles. Ptolemy gives the bright stars planetary natures in Tetrabiblos I.9; Agrippa, after Hermes and Thebit, gives fifteen of them a stone and plants (De occulta philosophia, 1533, I.32).
