Cancer; Libra; Taurus. Scorpio is considered fertile by most modern astrologers, despite being ruled by Mars (probably because it is feminine and watery). Pisces and Sagittarius are described by Ptolemy as "fecund". Pisces is fertile and fruitful, but is Sagittarius? Sagittarius (hot and moist) certainly likes to scatter seed to the winds, but does not seem particularly nurturesome to me. Still "fecund" does not mean "nurturesome", merely "able to reproduce prolifically" so it must be because prolific Jupiter rules them both. Lilly too says Sagittarius is fruitful – due to the influence of Jupiter being dignified there by both domicile and joy.
