that are written by such as commanded or were imploied themselves in weighty affaires or that were partners in the conduct of them, or that at least have had the fortune to manage others of like qualitie. Such in a manner are all the Graecians and Romans. For many eye-witnesses having written of one same subject (as it hapned in those times when Greatnesse and Knowledge did commonly meet) if any fault or over-sight have past them, it must be deemed exceeding light and upon some doubtful accident. What may a man expect at a Phisitians hand that discourseth of warre, or of a bare Scholler treating of Princes secret designes? If we shall but note the religion which the Romans had in that, wee need no other example: Asinius Pollio found some mistaking or oversight in Caesars Commentaries, whereinto he was falne, only because he could not possiblie oversee all things with his owne eyes that hapned in his Armie, but was faine to rely on the reports of particular men, who often related untruths unto him: or else because he had not been curiously advertized [Footnote: Minutely informed.] and distinctly enformed by his Lieutenants and Captaines of such matters as they in his absence had managed or effected. Whereby may be seen that nothing is so hard or so uncertaine to be found out as the certaintie of the truth, sithence [Footnote: Since.] no man can put any assured confidence concerning the truth of a battel, neither in the knowledge of him that was Generall or commanded over it, nor in the soldiers that fought, of anything that hath hapned amongst them; except after the manner of a strict point of law, the severall witnesses are brought and examined face to face, and that all matters be nicely and thorowly sifted by the objects and trials of the successe of every accident. Verily the knowledge we have of our owne affaires is much more barren and feeble. But this hath sufficiently been handled by Bodin, and agreeing with my conception. Somewhat to aid the weaknesse of my memorie and to assist her great defects; for it hath often been my chance to light upon bookes which I supposed to be new and never to have read, which I had not understanding diligently read and run over many years before, and all bescribled with my notes; I have a while since accustomed my selfe to note at the end of my booke (I meane such as I purpose to read but once) the time I made an end to read it, and to set downe what censure or judgement I gave of it; that so it may at least at another time represent unto my mind the aire and generall idea I had conceived of the Author in reading him. I will here set downe the Copie of some of my annotations, and especially what I noted upon my Guicciardine about ten yeares since: (For what language soever my books speake unto me I speake unto them in mine owne.) He is a diligent Historiographer and from whom in my conceit a man may as exactly learne the truth of such affaires as passed in his time, as
