Asteroid 571 Dulcinea was discovered on September 4, 1905, at Heidelberg, Germany, by Paul Götz, who named it for the idealized lady-love of Don Quixote de la Mancha in Miguel de Cervantes' novel Don Quixote.
Dulcinea has a period of 3 years, 271 days.
Astrologically, Dulcinea indicates searching for some ideal or idealized state or person, which (or who) may never be found.
Ronald Reagan has Dulcinea in the tenth house, conjunct the Midheaven (career, reputation, authority), square Mercury (communication) and Neptune (ideals, deception, delusion), and opposite Ceres (nurturance, emotional attachment). He has communicated very eloquently his idealized conservative political vision of America, which probably never existed in reality as is, and his followers generally overlook the fact that while talking the talk very well, he has never walked the walk as well.
Adolf Hitler expressed his mad dream of hate and power in part through his first-house Dulcinea, which conjoins Vesta (commitment), trines the North Node (developing gifts), sesquiquadrates Pallas (politics) and opposes Venus (values) and Mars (aggression).
Ayn Rand (born February 2, 1905, in St. Petersburg, Russia) had Dulcinea conjunct Mercury and Pallas, square Vesta and quincunx Pluto (transformation, power). She articulated a vision of a rational, capitalistic society, which is generally embraced by the political right, although it firmly excludes faith and the supernatural.
Archetypal sex symbol Marilyn Monroe had Dulcinea semisquare Saturn (career), trine Mercury, and quincunx the Midheaven. Journalist and writer Tommy Thompson, in his 1981 novel Celebrity, called her "the most desired woman on the planet."
The glyph for Dulcinea is mine.
