There have been a number of magic related periodicals called "The Zodiac".
ZODIAC, Zodiac Magical Society magazine
The ZODIAC is official monthly Magic Periodical of the Zodiac Magical Society in the United Kingdom. It started publishing in the 1960s under the direction of Freddie Firth, who performed the duties for over forty years until he retired in 2006.
ZODIAC, The Organ of British Magic
The ZODIAC, The Organ of British Magic, was a Magic Periodical published by an Arthur Ivey in London, that ran from 1928-29 for a total of 6 issues. This publisher should be distinguished from Arthur Ivey, the long-term curator of The Magic Circle museum, who published a disclaimer in The Magic Circular, 28 October 1928, vol. 23, no. 257, p. 13, making it known to members that "he is not the publisher of a new magical paper called The Zodiac, and is in no way connected therewith, though it is apparently sponsored by someone who bears the same name."
