You should check out "Cosmos and Psyche: Intimations of a New World View" by Richard Tarnas. He's a statistician who set out to debunk astrology once and for all. But when tracking astronomical movements against historical data he found "anomalies" that tied in with what Astrology was claiming. For istance the conjunction of Uranus with certain planets every 80 coincided with major socio-political upheavals. Good read, merges the two subjects you're discussing.
