stopped his horse outside the cave, and Simon, lurking in the shadows
within, had a fair view of him in the moonlight. He slipped from his
saddle, fastened the bridle to a root, and then stood peering through
the opening of the cell. He was a very short, thick man, with a dark
face, which was gashed with three cuts upon either side. His small eyes
were sunk deep in his head, showing like black holes in the heavy, flat,
hairless face. His legs were short and very bandy, so that he waddled
uncouthly as he walked.

Simon crouched in the darkest angle, and he gripped in his hand that
same knotted cudgel which the dead theologian had once raised against
him. As that hideous stooping head advanced into the darkness of the
cell, he brought the staff down upon it with all the strength of his
right arm, and then, as the stricken savage fell forward upon his face,
he struck madly again and again, until the shapeless figure lay limp and
still. One roof covered the first slain of Europe and of Asia.

Simon's veins were throbbing and quivering with the unwonted joy of
action. All the energy stored up in those years of repose came in a
flood at this moment of need. Standing in the darkness of the cell, he
saw, as in a map of fire, the outlines of the great Barbaric host, the
line of the river, the position of the settlements, the means by which
they might be warned. Silently he waited in the shadow until the moon
had sunk. Then he flung himself upon the dead man's horse, guided it
down the gorge, and set forth at a gallop across the plain.

There were fires on every side of him, but he kept clear of the rings
of light. Round each he could see, as he passed, the circle of sleeping
warriors, with the long lines of picketed horses. Mile after mile and
league after league stretched that huge encampment. And then, at last,
he had reached the open plain which led to the river, and the fires of
the invaders were but a dull smoulder against the black eastern
sky. Ever faster and faster he sped across the steppe, like a single
fluttered leaf which whirls before the storm. Even as the dawn whitened
the sky behind him, it gleamed also upon the broad river in front, and
he flogged his weary horse through the shallows, until he plunged into
its full yellow tide.

So it was that, as the young Roman centurion--Caius Crassus--made his
morning round in the fort of Tyras he saw a single horseman, who rode
towards him from the river. Weary and sp
