With the renewed interest in astrology, there is every reason for this sympathetic but objective treatment of the rise, history and present state of the (sic) science although it is not as easily read as it might be. Mr. Gleadow is a British astrologer and a Greek and Egyptian scholar with a number of surprising things to say. For one, it appears that there is a spirited controversy over which zodiac to use today (whether one based on the fixed stars or on the spring equinox). ""It is now evident that all horoscopes ought to be altered"" since the version in vogue for the last 2000 years was adopted more or less by mistake through the prestige of Ptolemy. The rest of the book tells how these things came to pass, working backwards (retrograde fashion, to borrow the jargon) through the ages. Compounding the difficulty is the language--""aspects,"" ""squares,"" ""conjunctions,"" etc. which Mr. Gleadow assumes the reader understands. He ends with some plausible arguments that the zodiac appeared first as a device for measuring time, and only later became involved in divination and analysis of character.... Some more serious scientific underpinnings for the Age of Aquarius.
