This one is a treat for the ears, as Jenn and Philip chat about astrological history, book collections, and more, including: why transit data from decades ago was all the same length; an auspicious voyage time as an unexpected popular topic; and astrological “modernizers.” Plus: watershed moments, when astrology went underground, and learning to cast charts!
