Laurence Sterne, Tristram Shandy (Chp. IV):
“It is in pure compliance with this humour of theirs, and from a backwardness in my nature to disappoint any one soul living, that I have been so very particular already. As my life and opinions are likely to make some noise in the world, and, if I conjecture right, will take in all ranks, professions, and denominations of men whatever,—be no less read than the Pilgrim’s Progress itself—and in the end, prove the very thing which Montaigne dreaded his Essays should turn out, that is, a book for a parlour-window;—I find it necessary to consult every one a little in his turn; and therefore must beg pardon for going on a little farther in the same way: For which cause, right glad I am, that I have begun the history of myself in the way I have done; and that I am able to go on, tracing everything in it, as Horace says, ab Ovo.
Horace, I know, does not recommend this fashion altogether: But that gentleman is speaking only of an epic poem or a tragedy;—(I forget which),—besides, if it was not so, I should beg Mr. Horace’s pardon;—for in writing what I have set about, I shall confine myself neither to his rules, nor to any man’s rules that ever lived.”
