successful he could make his own terms, and, among his spoil, if he
cared, should be the sister of the emperor.

At first it was Gaul that was to be plundered; but there, as we know,
the wild beast was met by Aetius who defeated him at the battle of
Chalons and thus saved the western provinces. But that victory was not
followed up. Attila and his vast army were allowed to retreat; and

Altinum became nothing. Nor have these cities ever lived again; out of
their ruin Venice sprang in the midst of the lagoons. All the
Cisalpine plain north of the Po was in Attila's hands; Vicenza,
Verona, Brescia, Bergamo, Pavia, even Milan opened their gates. No
defence was offered, they saved themselves alive. And southward, over
the Po, between the mountains and the sea, the gate which Ravenna held

moment, one of the greatest crises in the history of Europe, suddenly,
and without warning, the reality of that age, which had changed so
imperceptibly, was revealed. The material civilisation and defence of
