So they journeyed on together. The emperor was delighted with his new servant. All his soldiers were poor and weak compared to Offero.
In the evening when the soldiers rested, the emperor loved to listen to music. He had with him a harper who would play upon his harp and sing sweetly.
Once the harper sang a song in which the name of Satan was heard. At this name the emperor trembled and made the sign of the cross.
"Why do you tremble, Lord Emperor?" asked the giant.
"Hush!" said the emperor.
"Tell me, or I will leave you," said Offero.
"I tremble because I fear Satan," answered the emperor. "I made the sign of the cross so that he cannot harm me. He is as wicked as he is strong."
"Farewell," said the giant. "I seek Satan now. If he is stronger than you, I must serve him."
So he journeyed through the land and soon found Satan at the head of a large army.
"Where do you go? Whom do you seek?" asked Satan.
