Genethlialogy

Genethlialogy is the application of astrology to the birth of individuals, in order to determine information about the nature and course of a person’s life.

The term is derived from the Greek word genethlialogia (γενεθλιαλογία), which means “the study that pertains to nativities” or “the study that pertains to births”.

Genethlialogy is more commonly known in modern times as “natal astrology.”  Please see the entry on natal astrology for more information.
