The Beast-Jewel of Mars is a science fiction novella by Leigh Brackett.
Bark Winters was a painting, shambling ape, fleeting through dark and echoing pits of horror. Behind him hissed the lashes of the jeering mob, savagely exultant at having debauched still another proud Terran into something that crawled. All the dark secrets of Terran evolution were laid bare in this garden of evil, under that prism of hell!
The wise men of Caer Dhu were not so wise. They found the secret of Shanga, and they escaped their wars and their troubles by fleeing backward along the path of evolution.
The Beast-Jewel of Mars was first published in Planet Stories magazine in 1948. E-book: ePUB, 15,000 words, average reading time 1 hour and 15 min.
