Totila saw that they were completely without defence against these terrible projectiles.

The Goths sprang horrified from the walls, and sought shelter in the streets, houses, and churches. In vain! Thousands and thousands of arrows, spears, heavy beams, and stones hurtled and hissed in infallible curves upon their heads; whole blocks of rock came flying through the air, and fell crashing through the woodwork and slabs of the strongest roofs; while in the north the rams thundered unceasingly against the castle with ponderous strokes.

While the thick hail of projectiles literally darkened the air, the noise of breaking beams, the rattling fall of stones, the shattering of the ramparts, and the cries of the wounded deafened the ear.

The trembling inhabitants fled terrified into the cellars and vaults of their houses, cursing both Belisarius and the Goths.

But the horrified city had not yet experienced the worst.

In the market-place, the Forum of Trajan, near the harbour, stood an uncovered building, a sort of ship's arsenal, heaped up with old, well-dried timber, tow, flax, tar, and other combustible materials. Into this building came, hissing and steaming, a strange projectile, and immediately a flame shot high into the air, and, fed by the inflammable materials, spread with the speed of the wind.

The besiegers outside greeted the pillars of smoke which now arose with cries of exultation, and directed arrows and darts upon the place, to prevent the inhabitants from extinguishing the fire.

Belisarius rode up to Martinus.

"Capital, man of the circle!" he cried. "Capital! Who aimed the shot?"

"I," said Jochem. "Oh! you will be satisfied with me, general. Now, pay attention. Do you see that large house with the statues upon the flat roof, to the right of the fire? That is the house of the Valerians, the greatest enemies of the people of Edom. Attention! It shall burn."
