He began his reign with an ostentation of dutiful regard to the memory of Claudius, whom he buried with the utmost pomp and magnificence, pronouncing the funeral oration himself, and then had him enrolled amongst the gods. He paid likewise the highest honours to the memory of his father Domitius. He left the management of affairs, both public and private, to his mother. The word which he gave the first day of his reign to the tribune on guard, was, "The Best of Mothers," and afterwards he frequently appeared with her in the streets of Rome in her litter. He settled a colony at Antium, in which he placed the veteran soldiers belonging to the guards; and obliged several of the richest centurions of the first rank to transfer their residence to that place; where he likewise made a noble harbour at a prodigious expense.Antium, the birth-place of Nero, an ancient city of the Volscians, stood on a rocky promontory of the coast, now called Capo d' Anzo, about thirty-eight miles from Rome. Though always a place of some naval importance, it was indebted to Nero for its noble harbour. The ruins of the moles yet remain; and there are vestiges of the temples and villas of the town, which was the resort of the wealthy Romans, it being a most delightful winter residence. The Apollo Belvidere was discovered among these ruins.

To establish still further his character, he declared, "that he designed to govern according to the model of Augustus;" and omitted no opportunity of showing his generosity, clemency, and complaisance. The more burthensome taxes he either entirely took off, or diminished. The rewards appointed for informers by the Papian law, he reduced to a fourth part, and distributed to the people four hundred sesterces a man. To the noblest of the senators who were much reduced in their circumstances, he granted annual allowances, in some cases as much as five hundred thousand sesterces; and to the pretorian cohorts a monthly allowance of corn gratis. When called upon to subscribe the sentence, according to custom, of a criminal condemned to die, "I wish," said he, "I had never learnt to read and write." He continually saluted people of the several orders by name, without a prompter. When the senate returned him their thanks for his good government, he replied to them, " It will be time enough to do so when I shall have deserved it." He admitted the common people to see him perform his exercises in the Campus Martius. He frequently declaimed in public, and recited verses of his own composing, not only at home, but in the theatre; so much to the joy of all the people,'that public prayers were appointed to be put to the gods upon that account; and the verses which had been publicly read, were, after being written in gold letters, consecrated to Jupiter Capitolinus.
