Solar Biology

Hiram A. Butler’s "Solar Biology" presents a system of character, health, and destiny interpretation based on sun-sign astrology and related esoteric correspondences. It is historically important as an American popular astrological text that helped organize zodiacal ideas for a broad audience; readers will find sign descriptions, natal interpretation, and practical applications of solar symbolism.

Hiram A. Butler (1827–1916) was an American writer and lecturer associated with spiritualist and Theosophical currents. He wrote on metaphysical and esoteric topics, helping to disseminate late nineteenth-century occult and reformist religious ideas in the United States.
