"Thirty! The fateful number! It was an obvious summons and command from the mysterious deities. The thirty galleys were launched once more and the expedition set forth.
"It succeeded. They took the island by assault. The natives they simply exterminated. The tribe settled down; and the tombstone of the Kings of Bohemia was installed . . . in the very place which it occupies to-day and which I showed to our friend Vorski. Here I must interpolate a few historical data of the greatest significance. I will be brief."
Adopting a professorial tone, Don Luis explained:
"The island of Sarek, like all France and all the western part of Europe, had been inhabited for thousands of years by a race known as the Liguri, the direct descendants of the cave-dwellers part of whose manners and customs they had retained. They were mighty builders, those Liguri, who, in the neolithic period, perhaps under the influence of the great civilizations of the east, had erected their huge blocks of granite and built their colossal funeral chambers.
"It was here that our tribe found and made great use of a system of caves and natural crypts adapted by the patient hand of man and of a cluster of enormous monuments which struck the mystic and superstitious imagination of the Celts.
"We find therefore that, after the first or wandering phase, there begins for the God-Stone a period of rest and worship which we will call the Druidical period. It lasted for a thousand or fifteen hundred years. The tribe became mingled with the neighbouring tribes and probably lived under the protection of some Breton king. But, little by little, the ascendancy had passed from the chiefs to the priests; and these priests, that is to say, the Druids, assumed an authority which increased in the course of the generations that followed.
"They owed this authority, beyond all doubt, to the miraculous stone. True, they were the priests of a religion accepted by all and also the instructors of Gallic childhood (it seems certain, incidentally, that the cells under the Black Heath were those of a Druid convent, or rather a sort of university); true, in obedience to the practices of the time, they presided over human sacrifices and ordained the gathering of the mistletoe, the vervain and all the magic herbs; but, before all, in the island of Sarek, they were the guardians and the possessors of the stone which gave life or death. Placed above the hall of the underground sacrifices, it was at that time undoubtedly visible in the open air; and I have every reason to believe that the Fairies' Dolmen, which we now see here, then stood in the place known as the Calvary of the Flowers and sheltered the God-Stone. It was there that ailing and crippled persons and sickly children were laid to recover their health and strength. It was on the sacred slab that barren women became fruitful, on the sacred slab that old men felt their energies revive.
