Sulla after His Retirement
But, such as he was, this Don Juan of politics was a man of one mould. His whole life attests the internal equilibrium of his nature; in the most diverse situations Sulla remained unchangeably the same. It was the same temper, which after the brilliant successes in Africa made him seek once more the idleness of the capital, and after the full possession of absolute power made him find rest and refreshment in his Cuman villa. In his mouth the saying, that public affairs were a burden which he threw off so soon as he might and could, was no mere phrase. After his resignation he remained entirely like himself, without peevishness and without affectation, glad to be rid of public affairs and yet interfering now and then when opportunity offered.
Hunting and fishing and the composition of his memoirs occupied his leisure hours; by way of interlude he arranged, at the request of the discordant citizens, the internal affairs of the neighbouring colony of Puteoli as confidently and speedily as he had formerly arranged those of the capital. His last action on his sickbed had reference to the collection of a contribution for the rebuilding of the Capitoline temple, of which he was not allowed to witness the completion.
