"You shall do it," said Validus, "and you shall have the time."

"But I had not planned remaining in your country," dissented von Harben.

"You shall remain," said Validus. "You shall also write a history of the reign of Validus Augustus, Emperor of the East."

"But—" interjected von Harben.

"Enough!" snapped Validus. "I am Caesar. It is a command."

Von Harben shrugged and smiled. Rome and the Caesars, he realized, had never seemed other than musty parchment and weather-worn inscriptions cut in crumbling stone, until now.

Here, indeed was a real Caesar. What matter it that his empire was naught but a few square miles of marsh, an island and swampy shore-land in the bottom of an unknown canyon, or that his subjects numbered less than fifty thousand souls—the first Augustus himself was no more a Caesar than was his namesake, Validus.

"Come," said Validus, "I shall take you to the library myself, for that will be the scene of your labors."

In the library, which was a vault-like room at the end of a long corridor, Validus displayed with pride several hundred parchment rolls neatly arranged upon shelves.

"Here," said Validus, selecting one of the rolls, "is the story of Sanguinarius and the history of our country up to the founding of Castrum Mare. Take it with you and read it at your leisure, for while you shall remain with Septimus Favonius, whom with Mallius Lepus I shall hold responsible for you, every day you shall come to the palace and I shall dictate to you the history of my reign. Go, now, with Septimus Favonius and at this hour tomorrow attend again upon Caesar."
