"Barbarossa aspires to universal dominion. He seeks to hold in his own grasp all control of rights and liberties; he wishes to make paltry villages out of our independent cities. Everything must give way before his Imperial supremacy; all must bow at the footstool of the conqueror. Religion, the Church, all that which we look upon as holy, are in his eyes mere machines of government. Such is Frederic's gigantic dream of power; can we, I ask, negotiate with such a man? No! we must conquer, or perish in the attempt!"

The archdeacon had spoken calmly, but with energy, and all felt that he had by no means exaggerated the position. For a moment there was a profound silence, which neither Nigri nor Oberto dared to break, and then the street without seemed suddenly animated, there was a noise of hurried feet and shouts and cries of alarm. Nigri rushed to a window and anxiously inquired the cause.

"To arms! to the walls!" answered a citizen, who in full armor was hastening towards the ramparts; "the tower of Henry the Lion is moving on the city!"

"The tower! the tower!" cried Cino, pale with fear; "take my word for it, before nightfall there will be many mouths less to feed among our fellow-citizens!"

All the consuls seemed equally alarmed, the object of the council was forgotten, and they hastily withdrew. Nigri detained the archdeacon, and taking him on one side, said,--

"One moment, I beg you, my lord Galdini. The words spoken here might, if known, discourage the people. I trust that I may count upon your discretion."

"Your recommendation is needless," replied Sala; "not a word shall pass my lips. Let us hasten, with God's aid, to repel the assault." He pressed Nigri's hand, and the consul hurriedly buckling on his armor, they repaired to the ramparts.

CHAPTER XX.

THE ASSAULT.

Milan was in mortal fear. The colossal form of the monstrous machine approached still nearer to the doomed city. The streets were filled with an anxious crowd of women, children, and men-at-arms, all pressing with hurried steps to the scene of danger. From every door rushed the alarmed citizens, buckling their armor as they ran. Wagons filled with caldrons of pitch and boiling oil, creeked as they labored slowly forward, and the shouts of the leaders, the orders of the consuls, and the continued challenge of the sentinels, completed the wild and confused tumult. And still the tower moved slowly on.
