“Master,” said Oran, “it is the will of the brethren that you break your fast. You are old, and God has your glory. Give us peace.”

“Father,” urged Keir, seeing that Colum kneeled unnoticingly, his lips still moving above his black beard, with the white hair of him falling about his head like a snowdrift slipping from a boulder. “Father, be pitiful! We hunger and thirst for your presence. We can fast no longer, yet have we no heart to break our fast if you are not with us. Come, holy one, and be of our company, and eat of the good broiled fish that awaiteth us. We perish for the benediction of thine eyes.”

Then it was that Colum rose, and walked slowly towards the wall.

“Little black beast,” he said to the fly that droned its drowsy hum and moved not at all; “little black beast, sure it is well I am knowing what you are. You are thinking you are going to get my blessing, you that have come out of hell for the soul of me!”

At that the fly flew heavily from the wall, and slowly circled round and round the head of Colum the White.

“What think you of that, brother Oran, brother Keir?” he asked in a low voice, hoarse because of his long fast and the weariness that was upon him.

“It is a fiend,” said Oran.

“It is an angel,” said Keir.

Thereupon the fly settled upon the wall again, and again droned his drowsy hot hum.

“Little black beast,” said Colum, with the frown coming down into his eyes, “is it for peace you are here, or for sin? Answer, I conjure you in the name of the Father, the Son, and the Holy Ghost!”
