Justinian's envoy remained in Italy and observed the disturbing effect on King Theudahad of the news of Belisarius's landing at Catania, and of the news that simultaneously came from Dalmatia to the effect that Mundus had stormed Spalato. Theudahad saw himself threatened with the fate of King Geilimer the Vandal, his kinsman-for Geilimer and he had an aunt in common. Without consulting with his Council, he made a secret offer to the envoy to cede Sicily to Justinian and send him beside a yearly tribute of a crown of gold weighing 300 pounds; and a permanent detachment of 3,000 Gothic cavalrymen and their horses to serve cither in North Africa or on the Persian frontier, as Justinian pleased, and to be kept up to strength with yearly drafts of men and remounts. He also renounced his right to sentence Italian priests and patricians to death, or to confer patrician rank on any person without the consent of Justinian or his successors. He even agreed that the responses of the factions in the Hippodrome at Rome, whenever he took his place as President, should couple in loyal salutation Justinian's name with his own, and that a statue of Justinian should flank every statue raised to himself, standing on the right side, which is the more honourable one. This was to acknowledge the suzerainty of the East over the West. Theudahad put these undertakings in writing. He was in great terror, and wished to lay up a treasure of gratitude for himself in Constantinople, if ever it should be necessary for him to escape there from Italy.
But when further news came of the fall of Palermo and of the bloodless occupation of Sicily, Theudahad's heart failed him. He wondered whether the terms he had offered Justinian to prevent him from pressing the invasion of Italy were not perhaps insufficient; to promise Sicily to Justinian when he had already taken it might be regarded as an impudence – and of what worth was an offer of 3,000 soldiers and a yearly tribute amounting to a mere 20,000 in gold, and an abandonment of the right to create or punish patricians? He recalled the envoy, who was already on his way back, and took him into his intimate confidence, first binding him with the most dreadful oaths to keep the secret. The secret was that if Justinian rejected these terms Theudahad was prepared to better them. He would resign his title of kingship and hand over to Justinian the whole government of Italy. All that he asked in return was a comfortable private life, preferably near some centre of learning in Asia Minor, on a freehold estate with a secure annual rent-roll of at least 80,000 gold pieces a year. A messenger of his own accompanied the envoy with this offer in writing, but it was only to be produced if Justinian did not accept the other one.
Ambassadors are chosen for their loyalty and self-sacrifice to the cause of their royal master; thus Justinian's envoy did not hesitate to risk spiritual disaster by breaking his oath to Theudahad. He advised Justinian to refuse the first offer, for Theudahad's messenger had a better one in readiness for him. This offer was then produced, and Justinian accepted it with alacrity. None the less, he was for haggling about the rent-roll of the estate, until Theodora laughed at his notion of business – to risk losing all Italy for the sake of a few sacks of coin.
So far, everything was going so well for Justinian that he can hardly have been blamed for believing that God regarded him with especial favour – a belief of which the servility of his courtiers did nothing to disabuse him. But, before the envoy had time to return to Italy and ratify the treaty with Theudahad, the whole political situation suddenly changed again. Two pieces of news persuaded Theudahad that he had been a fool after all and had over-estimated Justinian's power to hurt him.
The first piece of news concerned Mundus. After his capture of Spalato, he had conic in contact with a large Gothic army and, after a stubborn battle in which both sides lost heavily, defeated it- but had himself been killed in pursuing the beaten enemy. It was reported that the Imperial forces were so reduced in numbers and spirit by this unlucky victory that they had returned to Illyria without even leaving a garrison behind at Spalato. The other piece of news was that a serious mutiny had broken out in North Africa, and that Belisarius was about to withdraw his forces from Sicily in order to restore order there. How true this African news was I shall presently tell. But its effect on Theudahad was so great that he spoke most insultingly to Justinian's envoy when he arrived, and even threatened to kill him on a baseless charge of adultery with a lady of the Court; he greatly repented of having written as he had to Justinian, and now declared that the envoy lied and that the two offers signed by himself were forgeries.
