Lucullus' daily entertainments were ostentatiously extravagant, not only in purple coverlets, and plate adorned with precious stones, and dancings, and interludes, but with the greatest diversity of dishes and the most elaborate cookery, for the vulgar to admire and envy. It was a happy thought of Pompey in his sickness, when his physician prescribed a thrush for his dinner, and his servants told him that in summer time thrushes were not to be found anywhere but in Lucullus' fattening coops, that he would not suffer them to fetch one thence, but observed to his physician, "So if Lucullus had not been an epicure, Pompey had not lived," and ordered something else that could easily be got to be prepared for him. Cato was his friend and connection, but, nevertheless, so hated his life and habits, that when a young man in the senate made a long and tedious speech in praise of frugality and temperance, Cato got up and said, "How long do you mean to go making money like Crassus, living like Lucullus, and talking like Cato?"It is plain from the anecdotes on record of him, that Lucullus was not only pleased with, but even gloried in his way of living. For he is said to have feasted several Greeks upon their coming to Rome day after day, who, out of a true Grecian principle, being ashamed, and declining the invitation, where so great an expense was every day incurred for them, he with a smile said to them, "Some of this, indeed, my Grecian friends, is for your sakes, but more for that of Lucullus." Once when he supped alone, there being only one course, and that but moderately furnished, he called his steward and reproved him, who, professing to have supposed that there would be no need of any great entertainment, when nobody was invited, was answered, "What, did you not know, then, that today Lucullus was to dine with Lucullus?" This being much spoken of about the city, Cicero and Pompey one day met him loitering in the forum, the former his intimate friend and familiar, and, though there had been some ill-will between Pompey and him about the command in the war, still they used to see each other and converse on easy terms together. Cicero accordingly saluted him, and asked him whether today was a good time for asking a favor of him, and on his answering, "Very much so," and begging to hear what it was, Cicero said, "then we should like to dine with you today, just on the dinner that is prepared for yourself." Lucullus being surprised, and requesting a day's time, they refused to grant it, and would not allow him to talk with his servants, for fear he should give orders for more than was appointed before. But this they consented to, that before their faces he might tell his servant, that today he would sup in "the Apollo" (for so one of his best dining-rooms was called), and by this evasion he outwitted his guests. For every room, as it seems, had its own assessment of expenditure, dinner at such a price, and all else in accordance; so that the servants, on knowing where he would dine, knew also how much was to be expended, and in what style and form dinner was to be served. The expense for the Apollo was fifty thousand drachmas, and such a sum being that day laid out, the greatness of the cost did not so much amaze Pompey and Cicero, as the rapidity of the outlay. One might believe that Lucullus thought his money really captive and barbarian, so wantonly and contumeliously did he treat it.
His furnishing of a library, however, deserves praise and record, for he collected very many choice manuscripts; and the use they were put to was even more magnificent than the purchase, the library being always open, and the walks and reading rooms about it free to all Greeks, whose delight it was to leave their other occupations and hasten thither as to the habitation of the Muses, there walking about, and diverting one another. He himself often passed his hours there, disputing with the learned in the walks, and giving his advice to statesmen who required it, insomuch that his house was altogether a home, and in a manner, a Greek prytaneum for those that visited Rome.
