“It is the convent-horn,” said Matheline.

“And it sounds the wolf-alarm!” added Pol.

“What harm can the wolf do,” asked Josserande, “to a well-mounted troop like the cavalry of Gildas the Wise? And, besides, cannot the holy abbot with a single word put to flight a hundred wolves?”

They had arrived at the heath of Carnac, where are the two thousand seven hundred and twenty-nine Druid stones, and the monks had already passed the round point where nothing grows, neither grass nor heath, and which resembles an enormous caldron—a caldron wherein to make oaten porridge—or rather a race-course, to exercise horses.

On one side might be seen the town, dark and gloomy; on the other, as far as the eye could reach, rows of rugged obelisks, half-black, half-white, owing to the snow, which threw into bold relief each jagged outline. Josserande, Matheline, and Pol Bihan had just turned from the sunken road which branches toward Plouharnel; and the moon played hide-and-go-seek behind a flock of little clouds that flitted over the sky like lambs.

Then a strange thing happened. The cavalcade of monks was seen to retreat from the entrance of the avenues to the middle of the circle, while the horn sounded the signal of distress, and loud cries were heard of “Wolf! wolf! wolf!”

At the same time could be distinguished the clashing of arms, the stamping of horses, and all the noise of a ferocious struggle, above which rose the majestic tones of Gildas the Wise, as he said with calmness:

“Wolf, wicked wolf, I forbid you to touch God’s servants!”

But it seemed that the wicked wolf was in no hurry to obey, for the cavalcade plunged hither and thither, as though shaken by convulsion; and the moon having come forth from the clouds, there was seen an enormous beast struggling with the staffs of the monks, the halberds of the armed guard, the pitch-forks and spears of the peasants, who had hastened from all directions at the trumpet-call from Ruiz.

The animal received many wounds, but it was fated not to die. Again and again it charged upon the crowd, rushed up and down, round and round, biting, tearing with its great teeth so fearfully that a large circle was made around the grand abbot, who was finally left alone in face of the wolf.
