In its centre an inspired-looking creature whirled about on his axis, the black ringlets standing out in snaky spirals from his haggard head, his cheek-muscles convulsively twitching.  Around him, but a long way off, the dancers rocked and circled with long raucous cries dominated by the sobbing booming music, and in the sunlit space between dancers and holy man, two or three impish children bobbed about with fixed eyes and a grimace of comic frenzy, solemnly parodying his contortions.

Meanwhile a tall grave personage in a doge-like cap, the only calm figure in the tumult, moved gravely here and there, regulating the dance, stimulating the frenzy, or calming some devotee who had broken the ranks and lay tossing and foaming on the stones.  There was something far more sinister in this passionless figure, holding his hand on the key that let loose such crazy forces, than in the poor central whirligig who merely set the rhythm of the convulsions.

The dancers were all dressed in white caftans or in the blue shirts of the lowest classes.  In the sunlight something that looked like fresh red paint glistened on their shaved black or yellow skulls and made dark blotches on their garments.  At first these stripes and stains suggested only a gaudy ritual ornament like the pattern on the drums; then one saw that the paint, or whatever it was, kept dripping down from the whirling caftans and forming fresh pools among the stones, that as one of the pools dried up another formed, redder and more glistening, and that these pools were fed from great gashes which the dancers hacked in their own skulls and breasts with hatchets and sharpened stones.  The dance was a blood-rite, a great sacrificial symbol, in which blood flowed so freely that all the rocking feet were splashed with it.

Gradually, however, it became evident that many of the dancers simply rocked and howled, without hacking themselves, and that most of the bleeding skulls and breasts belonged to negroes.  Every now and then the circle widened to let in another figure, black or dark yellow, the figure of some humble blue-shirted spectator suddenly “getting religion” and rushing forward to snatch a weapon and baptize himself with his own blood; and as each new recruit joined the dancers the music shrieked louder and the devotees howled more wolfishly.  And still, in the centre, the mad marabout spun, and the children bobbed and mimicked him and rolled their diamond eyes.

Such is the dance of the Hamadchas, of the confraternity of the marabout Hamadch, a powerful saint of the seventeenth century, whose tomb is in the Zerhoun above Moulay Idriss.  Hamadch, it appears, had a faithful slave, who, when his master died, killed himself in despair, and the self-inflicted wounds of the brotherhood are supposed to symbolize the slave’s suicide; though no doubt the origin of the ceremony might be traced back to the depths of that ensanguined grove where Mr. Fraser plucked the Golden Bough.
