- The classical seven include both luminaries.
Definition and identification
Classical astrology uses the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn as its seven principal actors. Astronomically the Sun is a star and the Moon a satellite; the astrological grouping reflects an older observational vocabulary. Glyphs make charts readable, but their usefulness does not validate the associated personality descriptions.
Structure and reading rules
A planet entry can separate longitude, sign, house and angular relationships before considering symbolism. Classical dignity systems include domicile and exaltation; modern psychological readings often use motivations or developmental themes. Uranus, Neptune and Pluto entered astrological interpretation much later and should not be silently inserted into an ancient seven-body table.
Concrete example
Ptolemy discusses the seven bodies through qualities such as heat and moisture. A modern guide may associate Mars with action or Venus with relationships. Comparing one body across an ancient description, a modern keyword list and its astronomical classification demonstrates changing vocabulary. It is not an experiment attributing an individual’s actions to a celestial body.
Historical context and limits
Benefic and malefic are historical technical labels modified by context, including day or night and position. They should not become moral judgments about people. Pluto’s astronomical classification and continued astrological use are separate questions. Sources show how writers interpreted the sky; predictive effects require separately specified and testable evidence.
