Zodiac and Swastika: How Astrology Guided Hitler's Germany (German: Tierkreis und Hakenkreuz: Als Astrologe an Himmlers Hof) is a 1968 book by Wilhelm Theodor H. Wulff (27 March 1892 - 9 June 1979).

The historian Nicholas Goodrick-Clarke takes the book as evidence that Wulff was consulted by Heinrich Himmler in the last weeks of the war.

[1] However, Goodrick-Clarke does not deal with Wulff's claim that as early as 1943 he got the assignment to locate Benito Mussolini, who had disappeared after being ousted from power.

Wulff claims that Arthur Nebe and Walter Schellenberg had assigned him various astrological tasks.

He also mentions that they had used pendulum dowsers like Ludwig Straniak for similar purposes.
