"Taurus is the first sign of the second Mesopotamian trigon, which included Taurus, Virgo and Capricorn. These trigons were always connected to the stars (sidereal) prior to the Tropical zodiac being adopted in western countries. These signs are primarily signs of communication and linking with other people. This is most clearly shown by the lords of two of the three signs of this trigon: Sociable Moon and Venus, the planet of relationships are linked to Taurus; and Mercury, planet of communication finds both its domicile (home) and exaltation in Virgo. Taurus is therefore connected to the arts (Venus) that involve communication."
"Ten years before Valerie Vaughan authored Persephone is Transpluto I had come to the conclusion that if a planet was discovered beyond Pluto, it would be named either Kore or Persephone, both names of Demeter’s (Ceres) daughter, and this planet would eventually come to be associated with Taurus. Because Kore spent part of her life above ground during the growing season and a third of the year underground during winter as the wife of Pluto, god of the underworld, this myth is well related to Taurus as a dual sign (Number 2) connected to spring and fertility (symbolism of the bull). Taurus also follows Aries in the zodiac, and Aries has been suggested as Pluto’s primary sign."
