Eager for fresh victories, he transferred his delirious court to Gaul, and declared that he was proceeding against the fierce Germans. The tribes were not in revolt, and the whole expedition was a comedy; some of the Roman writers say that a few tame captives were conveyed across the river and hunted, so that the Emperor might truthfully inform the Senate that he had gained a victory and merited a triumph. Suetonius even adds that, when he did eventually return to Rome and celebrate his triumph, a few slaves were forced to learn a little German and dye their hair, to pose as conquered tribesmen before his chariot. In the meantime, events which concern us more closely were happening at Lyons. The extravagance of Caligula was rapidly emptying the treasury. In twelve months he spent 2,700 million sesterces. His baths were of the most precious ointments; his banquets were especially designed to waste money--one alone cost £80,000, in modern coinage--and, when the flow was not fast enough, he drank pearls dissolved in vinegar, and had gold fashioned in the shape of food and served to his guests. He disdainfully swept the palaces of Octavian and Tiberius, with other mansions, from the Palatine, and erected a palace of extraordinary proportions and barbaric splendour. Such habits drew about him a crowd of ignoble parasites, and one can well believe that he had discovered a conspiracy against him at Lyons. He had prostituted the honour of Rome in a manner so childish and base that few could be unmoved. Observing the wealth of the Gauls--for Lugdunum (Lyons) was then the centre of a prosperous and cultivated region--he began to sell to them the possessions of the Imperial house. He was present at the auction, and the proceeds were so satisfactory that he sent to Rome for wagon-loads of furniture, heirlooms, and curios from the Imperial palaces, and, as they were offered for sale, pointed out himself the historical value of each object. In his suite was the first husband of his sister Drusilla. This distinguished noble, Lepidus, may have exchanged views on the insanity of the Emperor with the disgusted Gauls. At all events, Caligula sent word to the Senate that he had discovered a plot against his life, and added that his sisters, Livilla and Agrippina, had been convicted of adultery with Lepidus. He put Lepidus to death, and compelled Agrippina, a proud and spirited young princess, to carry on foot to Rome the urn containing the ashes of her alleged lover. We shall see how, on his return to Rome, Caligula made atonement to vice for this drastic punishment of adultery. In fact, he already had a mistress in the Court at Lyons, and this lady now displaces Lollia Paulina, and becomes the fourth Empress of Rome.
