"I know the Prefect of Rome," said the silent guest.

"Well, Cethegus," said Kallistratos, "this is my Vulcanic friend, Furius Ahalla, from Corsica, the richest ship-owner of the West; deep as night and hot as fire. He possesses fifty houses, villas and palaces on all the coasts of Europe, Asia, and Africa; twenty galleys; a few thousand slaves and sailors, and----"

"And a very talkative friend," concluded the Corsican. "Prefect, I am sorry for you, but the amphora is mine. I know the wine." And he took a Kibitz-egg and broke the shell with a silver spoon.

"Hardly," said Cethegus with a sarcastic smile.

"Nevertheless I do know it. It is Isis-wine. From Memphis." And the Corsican quietly sipped the golden yolk of his egg.

Cethegus looked at him in surprise.

"Well guessed!" he then said. "Where have you tasted it?"

"Necessarily in the same place as you. It flows only from one source," said the Corsican, smiling.

"Enough of your secrets! No riddles under the rose!" cried Piso.

"Where have you two weasels found the same nest?" asked Kallistratos.
