What to read after On the Art of War?

As I believe that it is possible for one to praise, without concern, any man after he is dead since every reason and supervision for adulation is lacking, I am not apprehensive in praising our own Cosimo Ruccelai, whose name is never remembered by me without tears, as I have recognized in him those parts which can be desired in a good friend among friends and in a citizen of his country. For I do not know what pertained to him more than to spend himself willingly, not excepting that courage of his, for his friends, and I do not know of any enterprise that dismayed him when he knew it was for the good of his country. And I confess freely not to have met among so many men whom I have known and worked with, a man in whom there was a mind more fired with great and magnificent things. Nor does one grieve with the friends of another of his death, except for his having been born to die young unhonored within his own home, without having been able to benefit anyone with that mind of his, for one would know that no one could speak of him, except (to say) that a good friend had died. It does not remain for us, however, or for anyone else who, like us, knew him, to be able because of this to keep the faith (since deeds do not seem to) to his laudable qualities. It is true however, that fortune was not so unfriendly to him that it did not leave some brief memory of the dexterity of his genius, as was demonstrated by some of his writings and compositions of amorous verses, in which (as he was not in love) he (employed as an) exercise in order not to use his time uselessly in his juvenile years, in order that fortune might lead him to higher thoughts. Here, it can be clearly comprehended, that if his objective was exercise, how very happily he described his ideas, and how much he was honored in his poetry. Fortune, however, having deprived us of the use of so great a friend, it appears to me it is not possible to find any other better remedy than for us to seek to benefit from his memory, and recover from it any matter that was either keenly observed or wisely discussed. And as there is nothing of his more recent than the discussions which the Lord Fabrizio Colonna had with him in his gardens, where matters pertaining to war were discussed at length by that Lord, with (questions) keenly and prudently asked by Cosimo, it seemed proper to me having been present with other friends of ours, to recall him to memory, so that reading it, the friends of Cosimo who met there will renew in their minds the memory of his virtue, and another part grieving for not having been there, will learn in part of many things discussed wisely by a most sagacious man useful not only to the military way of life, but to the civilian as well. I will relate, therefore, how Fabrizio Colonna, when he returned from Lombardy where he had fought a long time gloriously for the Catholic King, decided to pass through Florence to rest several days in that City in order to visit His Excellency the Duke, and see again several gentlemen with whom he had been familiar in the past. Whence it appeared proper to Cosimo to invite him to a banquet in his gardens, not so much to show his generosity as to have reason to talk to him at length, and to learn and understand several things from him, according as one can hope to from such a man, for it appeared to him to give him an opportunity to spend a day discussing such matters as would satisfy his mind.
