The Seven Crystal Balls
Hergé continued at the point where he had left "The Seven Crystal Balls", prior to embarking on "Prisoners of the Sun", although both were published under the title of "" ("The Temple of the Sun"). Rather than re-serialising the story from its beginning, he began the new magazine with a summary of the story so far, presented as a press clipping. The magazine was an instant success, soon gaining a weekly circulation of 100,000 in Belgium and the Netherlands. "The Seven Crystal Balls" serialisation finally concluded on 22 April 1948, four and a half years after it had begun.
